The lightsabers are indeed trophies taken from Jedi.

Grievous provided a not-so-subtle hint that the lightsabers he carried with him were trophies when he encountered Obi-Wan and Anakin on the bridge of the Invisible Hand near the beginning of Episode III: OBI-WAN, ANAKIN, PALPATINE, and ARTOO are captured by GENERAL GRIEVOUS.

They stand before the ALIEN DROID GENERAL. ...

GENERAL GRIEVOUS:

Your lightsabers will make a fine addition to my collection.

Star Wars :

Episode III Revenge of the Sith script Since he carries around a collection of lightsabers from Jedi

, it's no surprise that the lightsabers he uses have the Jedi blue and green colors.

Grievous isn't able to craft his own lightsabers and has to settle for taking them from the corpses of his Jedi opponents as trophies.

This explains their colours.

We have confirmation from the Lightsabers: A Guide to Weapons of the Force factbook that the four lightsabers belonged to various Jedi masters that Grievous had defeated; Shaak Ti (which he took from her in in a deleted scene ), Eeth Koth , Pablo-Jill and Roron Corobb .

Pablo-Jill Grievous claimed Pablo-Jill's lightsaber from floating debris, after Grievous injured him during an intense duel in a collapsing satellite city over Duro.

Roron Corobb

When General Grievous stormed the Republic capital, he cut through layers of security forces and Jedi protectors, including Corobb.

He was killed by Grievous while defending Chancellor Palpatine.

Eeth Koth Koth lost his lightsaber to General Grievous when the Separatist warlord captured him in the Saleucami system.

Shaak Ti As the last line of defense for Chancellor Palpatine, during the final battle of the Clone Wars, Grievous ensnared Shaak Ti with electrified cables, which knocked her unconscious and allowed Grievous to steal het lightsaber.

Out of universe, the swords used in his fight were a selection of generic blades that were used elsewhere in the films, including the "stunt" blade used by Obi-Wan in The Phantom Menace , the "hero" hilt and "stunt" blade used by Anakin and Obi-Wan in Attack of the Clones and the "stunt" blade used by Adi Gallia in the Arena fight.

Two reasons: First, as commonly discussed, the lightsabers are taken from the Jedi he captures or kills.

In the deleted scene in RoTS, before Anakin and Obi-Wan find Palpatine on the ship above Coruscant, they run into a bunch of Federation droids with Grievous and another Jedi named Shaak Ti.

Shaak Ti says, "Forgive me, Master Obi-Wan.

I have failed," and then she's killed with her own lightsaber by Grievous.

And Obi-Wan and Anakin say "You've just made a big mistake."

Later, when the two Jedi are captured along with Palpatine.

Grievous says "Your lightsabers will make a fine addition to my collection," and we see a couple of other lightsabers in his cloak, one of which we know is

Shaak Ti's.

So since the lightsabers he has are trophies from defeated Jedi, they would obviously be in the colours the Jedi commonly use: blue and green.

The other reason is more in-depth.

Why does he need to take lightsabers in the first place?

Because he can't make one of his own.

Why can't he make his own red lightsaber?

Because he was never a Jedi or a Sith.

He did say, before he fought Obi-Wan on Utapau that he had been trained in the Jedi arts by Count Dooku.

However he says " Your Jedi arts", which means he isn't one of them , meaning Obi-Wan and Dooku, who are Jedi and Sith respectively.

It is noted that only Sith or Jedi can make their own lightsabers, and it is considered the final test of a Jedi to be able to construct one of their own, as implied by Vader's statement to Luke on Endor in RoTJ:

"So I see you have constructed a new lightsaber.

You're skills are now complete."

However, Grievous could never make a lightsaber of his own, because he could not become a Jedi or a Sith, because he had no midichlorians.

They live in people's blood and allow them to control the Force.

However, since Grievous was mainly droid, with what looked like a heart that Obi-Wan shot in the end, he could not use the midichlorians (if he had any), so he could not control the Force.

Thus he could not make a lightsaber.

Thus, he had to use lightsabers taken from defeated Jedi.

Yes, they were trophies acquired from the Jedi.

In fact, the first blue lightsaber was taken from Master Sifo-Dyas by Count Dooku himself, and later handed over to Grievous as a gift.

Wookieepedia states : Once Grievous' transformation into a cyborg had been successfully completed, Dooku gave him the very special gift of Master Sifo-Dyas' own lightsaber.

The green lightsaber was stolen from Master K'Kruhk on Hypori.

Wookieepedia says : However, Grievous did steal K'Kruhk's green lightsaber.

The weapon became one of Grievous' favorites, the cyborg keeping it handy and using it up until and including his final battle with Obi-Wan Kenobi on Utapau.

Grievous took the second blue lightsaber from Adi Gallia when he struck her down on Boz Pity.

The second green-bladed weapon was collected from Master Ur-Sema Du , as explained in Wookieepedia : Wielding her lightsaber against Grievous' electrostaff, Du fought valiantly but was overpowered and killed by the General.

Collecting her lightsaber as a trophy, Grievous left her body where it laid, his existence remaining a secret from the Republic until he was ready to unleash his full might on the Grand Army of the Republic.

Grievous took them from Jedi he defeated in the Clone Wars.

The deleted scene from Episode III in the other question is related to this scene from the 2003 Clone Wars cartoon series .

This is how Shaak Ti gets captured and how he gets at least two other lightsabers.

You'll note that Grievous starts with at least one and then kills the other Jedi and takes theirs.

Sadly the cartoon is no longer considered canon, despite it explaining a good amount of backstory between episodes 2 and 3

Question: In  Revenge of the Sith , General Grievous has four lightsabers. Later on in the film, we see him use those lightsabers when he fights Obi-Wan and there's not a single red lightsaber - just 2 blues and 2 greens. Are they trophies?

Why does General Grievous have blue and green lightsabers instead of a red lightsaber?

The blue and green lightsabers used by General Grievous are indeed trophies taken from Jedi. This is because Grievous isn't able to craft his own lightsabers, therefore, he steals them from defeated Jedi.

The lightsabers have been taken from Jedi that Grievous has defeated and killed. He takes them because he is unable to make his own lightsaber as he is neither a Jedi nor a Sith


"Turning to face a wall" isn't going to do jack squiddly against a facehugger.

They're literally built to hug your face and plant eggs in your chest, and nothing you can do as a lone human is going to prevent that once they've jumped at you.

Their little ovipositor (Egg Injector) secretes a kind of acidic substance that allows them to pierce pretty much any material.

It got through Kane's helmet, after all.

So if they wanted, they could probably just make a new hole at the back of your head after you've turned around.

Best defence against a facehugger if you're by yourself is to have a shotgun or a flamethrower in your hands and blast every last one that thinks you're a good place to start a hatchery.

It's hard to say for sure, but in Aliens at least, it takes the combined effort of 4 adults (3 of which are marines, 1 of which is Vasquez .

Although arguably, Ripley might not be giving it her all), to pry a facehugger off Ripley.

We'd have to assume they are very strong creatures and so facing a wall or covering your face with your arms

probably wouldn't be adequate protection.

And like Mikey Mouse points out in the comment below, their first job is really to choke you unconscious.

After you pass out, it doesn't really matter what direction your facing.

That's like saying that I can't punch you in the face if you're looking the other way.

Technically true, but unlikely to be of any practical help.

However, to answer the original question, in the Aliens: Berserker comic, a team of alien removal specialists use special anti-facehugger masks, which allows someone to get taken alive for impregnation, and thus reveal the location of the hive.

Facehuggers have a variety of ways of giving you a face full of alien wing-wong.

As we see in most movies, the prefer to attack by surprise, are extremely fast and are capable of very long jumps, leaving you with no time to turn away.

They also seem to strike the neck of their victim (as seen in Aliens and AVP ), throttling them into near unconsciousness before settling onto the face of their victim.

As we see in

Alien

they are also capable of secreting acid capable of melting through a very thick looking space helmet, so covering your face with your arms might not be a good idea.

In some of the expanded universe material, such as Earth War , one character remarks that he's even seen facehuggers take down adult lions.

It wouldn't work.

Their design (strength, agility and process) is to subdue first on contact and use as an incubator when successful.

Short of killing them, what would work is figuring out how they aim, and either give them a false target (a clay head?

ballistic gel?

mirror?

hologram?)

or be somewhere

they can't get to.

(so, be an unreachable/invisible target)

For example, live on a planet while they are stuck in a star's gravitational pull.

They won't get near you.

Bishop said in Aliens, that as soon as the alien had planted the embryo, the blood of the facehugger quickly oxidizes and the creature dies.

Since many types of glass won't melt with acid, and seeing that it's very difficult to remove one of those organisms, once attached, why not use a syringe with a glass needle (glass that is tempered to their acidity) and inject an oxidizing agent?

Even a strong base to neutralize the acid blood and thereby killing the creature before it finishes the gestation period.

Then you pull it off and see if you can extract the embryo before it matures.

I also wonder what localized liquid nitrogen would do to their tissue?

Well, how about using an ape suit?

They're canon: http://avp.wikia.com/wiki/Apesuit

The Apesuit is a specialized armored suit, used by both the United States Colonial Marine Corps and Weyland-Yutani combat personnel.

The suit effectively protects the wearer from the hazardous effects of Xenomorph acidic blood.

[...] it additionally protects the wearer from Facehugger attacks as long as they are not comatose, as the Facehugger will then have time to pry the suit's mask off and gain access to the victim within.

The Apesuits in this game are considerably bulkier than those seen previously.

You could, but the tail would choke you out until you lost consciousness, and then the fingers, which are apparently very strong, would clamp onto your head and not let go.

That nasty tube would be down your throat before you knew it.

Question: I think I found a flaw to the alien franchise. As the other day I was wondering if you can just cover your face against a wall or your arms? I mean if you've been cocooned then you can't move your head so your doomed there but if you just hide your face the facehugger can't get you.

Can you hide your face from a facehugger?

It is generally agreed that you cannot simply hide your face from a facehugger.

Turning to face a wall would not help you, as the facehugger could simply throttle you from behind and turn you round once you had lost consciousness, or otherwise use its strength to overcome you.

Turning to face a wall would not be an effective defence as the facehuggers ovipostor can get through pretty much anything.

Facehuggeres are so strong it took 4 adults to get one off Ripley's face.

Turning away would be like turning away from someone threatening to punch you in the face - but you could survive with an anti-facehugger mask.

Facehuggers often go for the neck to throttle their victims so turning away won't help. They can kill adult lions.

They are too strong, agile and cunning to be foiled by someone just turning away.

You might be able to fight back using a syringe full of an oxidising agent or a strong base - or even liquid nitorgen.

If you turned away they would just strangle you until you lost consciousness and then clamp onto your head and plant the eggs.


Best example I can think of is in Star Wars Rebels, Season 1 Episode 1 (Droids in Distress), a barely trained (virtually untrained?)

Ezra does a Force push on Agent Kallus to save Zeb at the very end of the episode.

The first thing Kanan said to Ezra following that incident: Kanan: Your formal Jedi training starts tomorrow

This leads you to believe that Ezra has not had much, if any, Jedi training prior to this incident.

This is reinforced by some discussions earlier in the episode between Hera and Ezra in which he confides in her that he has not really received any training so far.

I don't have the exact quote handy, but I believe Ezra's response to her question about how his training is going is "What Jedi training".

In The Phantom Menace, Qui-Gon indicates the only reason young Human Anakin can compete with alien pod racers who have better senses or more than two grasping limbs, is because of his innate Force use.

QUI-GON : He can see things before they happen.

That's why he appears to have such quick reflexes.

It is a Jedi trait.

And who says Rey has no Force training.

We don't know much about her past, but given the age she was left behind, the old Jedi Order would have already started her training.

And she could have picked some things up from all of the time Kylo used his own Telepathy on her.

In the legends X-Wing series of books Corran Horn (without training in the force) uses non-vocal force persuasion to discourage a stormtrooper from finding him while he is hiding. http://starwars.wikia.com/wiki/X-Wing:_The_Krytos_Trap

In The Clone Wars episode Children of the Force , there are newborns and small children that were already being found by the Jedi but not yet taken.

They could already levitate their toys.

Mind trick was not used there, but still though if one looks at Luke Skywalker even levitating things doesn't seem to be too easy (and I wouldn't count mind trick as advanced...

stopping blaster shots mid-air or deflecting them with the hand I would count as advanced).

Entire population of planet

Haruun Kal 's population was described as force sensitive in Republic comics.

They are considered as "Legends" now I guess.

An example would be Kar Vastor .

Indigenous to Haruun Kal, learned about ways of the force by himself in a jungle, at least according to Legends.

He even managed to beat Mace Windu into unconsciousness once.

If every Force-sensitive user needs a Force-sensitive master... ...who taught the first ever Force-sensitive master how to use the Force?

Logically speaking, at least one Force-sensitive individual has to have had the ability to use the Force without training or else no one would have been able to use the Force in the first place.

The Force is intuitive first; technical later.

Think back to Luke's initial training with Obi-Wan and the Marksman-H combat remote droid .

Kenobi didn't physically lead Luke through the "motions" of using the Force in order to blindly deflect the blaster bullets.

He didn't hold Luke's hands and say, "Swing like this ".

He provided simple verbal commands to guide Luke into connecting with his abilities-

it was up to Luke to discover what the Force actually felt like when tapped into and thus how to manipulate it.

As far as I'm concerned, Luke is an untrained Force user who does end up deflecting shots from the remote droid through use of the Force- just with a little encouragement from Obi-Wan.

Rey had more "training" in the art of the Force Mind Trick than Luke did when it came to Force Precognition .

Rey at least had the misfortune (but advantage) of seeing and experiencing Kylo Ren's Mind Probe which she intuitively was able to block by tapping into that specific area of the Force.

From there, she need only apply her newfound power at getting into the mind of someone else.

On the other hand, Luke was told to strap on a helmet, become blind, pick up a very complicated weapon, and then deflect small blaster bullets with the "edge" of said

complicated weapon- all without having the luxury of watching someone else do it or feel the ripple in the Force as another person performs the feat.

But then again, that's part of what makes Luke truly such a naturally powerful Force user.

Before Luke met Yoda, he could do some basic telekinesis with no real force training.

Another Legends Example:

In The Force Unleashed (Video Game)

Star Killer can already grab a lightsaber using telekinesis as a toddler.

Although it is not impossible he may have received training shortly after birth, it is very improbable.

Young Asajj Ventress instinctively Force-pushes a Weequay raider away from herself in Clone Wars, "Nightsisters" (Episode 12).

Kajin Savaros uses Force Push to actually disintegrate an Inquisitor on Coruscant.

If I recall correctly, Han Solo's intuition, "I've got a bad feeling about this", was attributed to his being a force sensitive.

So completely untrained, he didn't even really believe in it at the time.

I believe the source for that was either the formerly cannon novels or one of the RPGs.

Question: In Star Wars The Force Awakens,     We see Rey, a seemingly untrained Force sensitive, use a Jedi mind trick with seemingly no training.   I have a friend who claims it would be impossible for any untrained Force-sensitive to use an "advanced maneuver"     like the mind trick.   Have we ever seen an untrained Force-sensitive individual use such a Force Power prior to The Force Awakens?  Canon is preferable, but Legends will work in addition to a canon answer.  Note:  Precognition or flying skills do not count as Force powers.

Have we ever seen an untrained Force-sensitive using Force powers?

It would be only an assumption to say that Rey has not received any force training. Very little is stated about her backstory. However, there are in any case various examples of force-sensitives seemingly using the force having received little or no training. These examples include Corran Horn, Kar Vastor and even Luke Skywalker, depending on your definition of "training".

There are many examples of innate use of the Force prior to awakening - such as the Clone Wars  episode  Children of the Force , where newborns and small children not yet taken by the Jedi can levitate toys.

Anakin is described as using innate Force power when out-competing alien pod racers in the Phantom Menace. It is also possible that Rey did have some training.

Corran Horn in the X-Wing books uses non-vocal force persuasion to fool a stormtrooper when in hinding.

In  The Clone Wars  episode  Children of the Force , newborns and small children not yet taken by the Jedi can levitate toys.

Kar Vastor taught himself about the ways of the Force when living in a jungle, after which he even managed to beat Mace Windu.

If all Force users needed a Master who could have trained the first Master? Various incidents from the training of Luke provide evidence of his innate ability to use the Force.

Star Killer was able to grab a lightsaber even as a toddler.

In Clone Wars Episode 12 Asajj Ventress instinctively Force-pushes a Weequay raider away.

Kajin Savaros uses Force Push to actually disintegrate an Inquisitor on Coruscant.

When Han Solo says "I've got a bad feeling about this", his intuition was attributed to his being a force sensitive even tho completely untrained.


Seat belts feature in a number of Star Trek properties that significantly pre-date

Star Trek Beyond .

They were seen in a deleted scene from Star Trek:

Nemesis In Star Trek Into Darkness

Shuttlecraft also have them in various episodes of TNG

The Animated Series (TAS: "Once Upon a Planet")

during a gravity loss scenario .

You can also see that Archer's chair (which looks very suspiciously like Picard's unused prop from Nemesis) has been retro-fitted with slots for shoulder straps in Enterprise, albeit we don't see their use.

That all depends on your definition of " Seatbelts ".

The first bridge seat restraint system was seen in Star Trek: The Motion Picture .

On the Captain's chair, the seat arms folded down over the lap during emergencies.

In addition to the other fine answers, seat belts were used the first time humans achieved warp

( Star Trek:

First Contact ):

In ST3: The Search for Spock , the crew of the Excelsior use some kind of seat restraint just before they go to trans-warp.

#No

There were seat belts used in the TNG era as well as in the new, alternate timeline.

The alternate timeline version of the Enterprise has seat belts that sort of craw or unroll onto your body.

There is a scene where someone is knocked out, put into a chair, and then a button is pushed to activate seat belts/safety restraints to avoid injury.

One of the TNG feature films included a scene in which Cpt.

Picard (and others) are strapped in use some sort of heavy duty seat belts.

Question: At one point in  Star Trek Beyond , everyone fastened their seat belts. At last! Is this the first time in  Star Trek  (TV, movies) that seat belts have been used?  If not, what was the first time?

Were seat belts used in Star Trek for the first time in Star Trek Beyond?

The answer to this question depends on the definition of "seatbelts". The first restraint system might have been used in Star Trek: The Motion Picture. Furthermore, there were seatbelts or at least seatbelt-like restraints used in TNG and Enterprise

Views vary - it may be that Star Trek: The Motion Picture was the first time seat belts were used but they may also have been used ever since humans developed warp and both in the TNG era and the new timeline.

Depending on your definition, the first time was the bridge restraint system in Star Trek: The Motion Picture.

Seat belts were first used when humans first achieved warp.

The Excelsior crew use some kind of seat restraint just before going trans-warp.

Seat belts were used both in the TNG era and in the new timeline.


The jet is not just a generic plane, but the X-Men's own custom and private jet, the Blackbird (inspired by the real-life Lockheed SR-71).

As the school is actually a training ground for mutants, and as over the years we have seen many X-Men piloting it, it seems reasonable to think that part of their training involves at least being able to fly it under normal circumstances.

Apart from that the plane contains a copy of Cerebro (and Cerebra, later), so it can probably fly even on its own.

Way back when, in Uncanny X-Men #143 , (cover-dated March 1981, which I think means it first became available in comic book speciality shops around December of 1980), Kitty Pryde had her first solo adventure.

She was still very much the "new recruit" at that point, having only been residing in the X-Mansion, and getting trained by Professor X, for the last few issues before that.

She was a mere thirteen years old.

But when a creature called a "N'Garai Demon" (shamelessly modeled on the monster from the original Alien movie with Sigourney Weaver) invaded the mansion in search of revenge on the X-Men (because of a previous fight -- long story!), Kitty tried various ways of coping with it, and finally ended up luring the demon into approaching the Blackbird from the rear, where she could fire up all the engines at once and incinerate it in the sudden blast.

I found a a scan of part of that sequence from the original story.

(Not showing the incineration, but what leads up to it as Kitty begins working out a new plan and moves into position.)

Please note that in the last panel on the bottom right, Kitty is thinking:

I don't see it yet, in the tail camera.

Now to run through the ignition check list.

Please, Lord, don't let me forget anything.

So her thoughts and actions in that scene made it crystal-clear that, even at this early stage in her career, when she was still a thirteen-year-old recruit, her training had already included memorizing the full checklist of things to do in the cockpit of the Blackbird before takeoff.

And how to actually fire up the engines, etc., after you'd done everything else!

This demonstrates that, by that time, Professor X had evidently decided that part of the curriculum for new mutant students went this way:

"Start teaching them how to fly the Blackbird as soon as possible , since you never know when a worst-case scenario may come along which makes it a matter of life and death for any available X-Man to know what to do in the cockpit!"

(And let's face it: the superhero lifestyle being what it is, "worst-case scenarios" do tend to keep happening!)

Since Colossus had already been an X-Man for a while at that point (he joined at the same time that Storm, Wolverine, Nightcrawler, and some others did in the comic books of the mid-1970s), it's a safe bet that by this point he was already an experienced pilot of the X-Men's regular Blackbird, even if he didn't get to show it very much.

(As I recall: Scott Summers, aka Cyclops, seemed to be the most frequent choice for pilot when the entire team was traveling long distances.)

By now, I suspect that the comic book version of Colossus could practically fly the thing in his sleep, if necessary.

So I see no reason to assume things are much different for a movie version of the character.

He may not be a great pilot, but he's probably been "cross-trained" so that he can function at the helm of the Blackbird if the more gifted pilots among the X-Men are unavailable at the time.

All senior students of the school (X-men and New Mutants) are taught how to fly a plane, specially the Blackbird.

This is issued several times across the comic

Since only Colossus and Negasonic were there, and since they flew the Blackbird, clearly at least one of them was capable.

This should not be surprising since in X2, Rogue and Iceman, both rather junior members of the team also flew the Blackbird.

Either the Blackbird is really easy to fly (unlike its real life counterpart), or Professor Xavier really packs the skills training in, or both.

The Negasonic Teenage Warhead shown in the movie is a new character, with different powers than the one in the comics.

Therefore, all we know about her capabilities is what's shown in the movie.

So, even if we had reason to think Colossus couldn't fly the plane (which we don't), we could safely conclude that she could.

Question: In  Deadpool,  we are shown Colossus and Negasonic Teenage Warhead walking to the X-Men plane and then in the next scene we see the plane take off.      I have never seen anything in the comics or in the Marvel Cinematic Universe that either of them can fly a plane.   Was it Colossus or Negasonic Teenage Warhead flying the plane? Or did they have a pilot fly it for them?

Can either Colossus or Negasonic Teenage Warhead actually fly a plane?

Since Colossus and Negasonic Teenage Warhead were on the plane, it's safe to assume that at least one of them could indeed fly it. Since Colossus was an X-man, it's also safe to assume that he may have received training to be able to fly the X-Men plane. As for Negasonic, although there is no reason to believe that she could fly, there is also no information to suggest that she could not.

There are numerous instances of junior students at the X-Men school flying the Blackbird so it is reasonable to assume that either Negasonic or Colossus can fly it.

The plane is a customised Blackbird and as the school is a training ground for mutants it is reasonable to assume that they have been trained to pilot a plane.

Even a 13-year old recruit has been depicted as knowing how to operate the controls of the Blackbird - back in a 1980 comic book story called Uncanny X-Men #143.

It is actually mentioned several times in the comic that all senior X-Men school students are taught how to fly a place and the Blackbird in particular.

Either Colossus or Negasonic must have flown the plane, but this is no surprise as other junior team members have also flown it.

We are not told specifically that Negasonic has been taught to fly a place, but based on her capabilities it is reasonable to assume that she could.


Imagine you grew up a farm boy in some podunk town in Backwater, Nebraska, where nothing ever happens.

All your life you have never been further than 20 miles from the place you were born, and in that 20 miles there is nothing but corn.

You are still in high school, and you realize your instructor used to be a Navy SEAL.

And a secret agent.

And walked on the moon.

And advised the president.

That is the level of excitement that Luke experiences when he learns who Ben is.

Things like Jedi and the Clone Wars, even though they are relatively recent events, they are distant enough from Luke's tiny existence to be legendary to him.

Luke entering that larger world is a major part of the story of Star Wars.

I don't think that audiences really appreciate that any more now that the prequels have been made.

When Obi-Wan mentions Luke's father, Luke asks, "You fought in the Clone Wars?" to which Obi-Wan replies, "Yes, I was once a Jedi Knight, the same as your father.

" They then proceed to talk about what happened to Luke's father.

Luke never mentions how long ago the Clone Wars were, nor even expresses much surprise that Obi-Wan was involved.

Over-all, he takes the news quite well.

Here's a link to the clip.

It wouldn't really be surprising if Luke did think the Clone Wars were "so long ago."

After all, when you've only been alive for 20 years, 20 years is a very long time.

Most 20 year-olds today would say the '90s were "so long ago," too.

It seems my memory played a [Jedi mind] trick on me:

The quote

"But that was so long ago" is actually from the novelization of the movie that was authored by George Lucas before the movie came out (which is weird - the movie opened at the end of May 1977, but the book was published in November 1976!).

As @Rogue Jedi pointed out in his comment, it was really ghostwritten by Alan Dean Foster.

While most of the book is in line with the movie, and material from the book later became canon ('Senator Palpatine' is mentioned for the very first time here!)

, there are changes.

This appears to be one of them - movie Luke seems only mildly surprised to learn of Obi-Wan's involvement in the C.W., and doesn't mention the time aspect at all.

For more on the book, including some of the ways it differs from the movies, see this link: Star Wars: From the Adventures of Luke Skywalker

Beyond the fact that clone wars was quite a while before, and Luke is a young man, it is not unreasonable to expect that anyone left on the losing side of the war, would be dead.

The Jedi were supposedly killed off, and Luke did not know Obi Wan was a Jedi at that point.

The other major group of combatants - the clones - aged at double the normal rate and would be long dead, if they survived the war.

Another thing to consider is the fact that the clone wars were mainly fought on core worlds, and mention of the war on outer rim worlds would have been rare.

And wouldn't you be surprised if an old hermit under a bridge told you he was a WWII General?

Question: In  Star Wars IV: A New Hope , Luke sounds surprised to learn that Obi-Wan fought in the Clone Wars. I haven’t watched it recently, but I think he even said, “…but that was so long ago!?”  But according to the prequels, the Clone Wars lasted at least until Luke’s birth. So we’re talking about 20 years - not a lot of time at all!?

Why was Luke surprised that Obi-Wan had fought in the Clone Wars?

Luke does not really express that much surprise, but he does believe the Clone Wars to have been "long ago". In reality, this is quite acceptable, given that he is so young. When you've only been alive for 20 years, 20 years is a very long time.

The Clone Wars seem long ago to Luke because they ended around the time of his birth 20 years earlier and to any 20 year-old that will seem a long time ago.

Luke is just excited because Obi represents a distant and dramatic world far from the quiet backwater he has known all his life.

Luke says the wars was "long ago" only because he is a young man and so events dating back to his birth do seem long ago.


Doctor Strange initially discovers the ability and perhaps would have attempted to heal his hands if he was not interrupted.

After he was interrupted, he did not have another opportunity because of the fast paced action afterwards.

By the end of the movie, his focus is no longer on healing himself and he may view his hands of a reminder of how he got where he is.

Also possible is that Doctor Strange believed Wong.

Wong told him there were serious consequences for using it, and Doctor Strange apologized and only used it later in the movie for important matters such as saving the world.

Wong tells Strange about the dangers of using the Eye, including the possibility of time loops and paradoxes.

There is no evidence in the movie that the Eye can be used to reverse time for a single object, so using it to fix his hands would require reversing time all the way back to prior to the accident.

This would create a paradox, since he would no longer have a reason to end up searching for Kamar-Taj and a way to heal his hands.

Of course, he does use the Eye to reverse time later, and even intentionally create time-loops, but only when there is no other recourse, and no real danger of creating a paradox.

On several occasions during the film it is pointed out that using the Eye of Agamotto to manipulate time is, at best, risky.

It’s not hard to imagine that turning back time for just one part of his own body might cause much more damage than Strange’s original injury, to him and/or the space-time continuum at large.

He chose not to.

He got past his ego and finally realised that it was not about him, as the ancient one said.

Healing his hands would mean he is choosing to live as the old Strange and not embrace his responsibilities as a sorcerer.

It's because he doesn't care to heal his hands.

As he descovered his new calling.

He wasn't obsessed with his past profession and life anymore

Question: In the movie,     Strange finds the Eye of Agamotto and notices it can manipulate time. He can manipulate individual objects such as an apple from being fresh to completely moldy and rotten. It is later shown he can use the time warping power with one hand and that there is at least one Master who is missing a hand altogether and can still perform magic spells.    Why didn't Strange use this to heal his broken hands, one at a time?

Why didn't Dr. Strange do this to heal his hands?

There are many possible explanations for why Doctor Strange did not choose to heal his hands. One is that he was interrupted and did not have enough of a chance to focus on healing his own hands. Another possibility is that, as Wong warned him that there would be serious consequences for using the eye, he chose not too. It's also plausable that he simply chose not to and had discovered his new calling.

Doctor Strange was warned of the risks of using the time travel powers and also he had moved on and was not focused on helping himself by that point.

Doctor Strange did not use the time travel powers to heal his hands because Wong warned him of the dangers of doing this.

He chose not to use the time powers to heal his hands because he had grown beyond self-interest and was immersed in his new calling as a sorcerer.

It's referring to the T-16 skyhopper.

It's the airship Luke owns in episode four.

When they say that there is a replacement they specifically say

the T-15.

In A New Hope you also see Luke playing with a model of it.

I believe they're discussing the VT-16 .

This is the same topic the Stormtroopers in A New Hope discuss while Obi-Wan Kenobi is disabling the tractor beam.

Curiously the Wookieepedia article suggests this is a droid seen in Return of the Jedi.

Personally I'd dispute that as it seems an odd thing for Stormtroopers to discuss, and I'd assume that VT-16 and BT-16 are different things.

But the link above does quote the conversation from A New Hope.

EDIT:

After a second viewing they definitely say T-15.

I now believe the quote on Wookieepedia is misplaced, and that those Stormtroopers are actually discussing the T-16, not VT-16.

This line in Rogue One was apparently a mis-quote by the voice actors that somehow made it into the completed film.

They were trying to back-reference the line from A New Hope complaining about the famously obsolete VT-16 (an item that has no canon

existence other than to be complained about).

“Without saying a word, without being called upon, and without evenlooking at each other, Sam and I stood up from our chairs and walkedup to the array of microphones in front of the movie screen.

Matthewsaid, ‘Okay, we need some kind of stormtrooper dialogue here,guys . . .

oh, looks like you’re ready

, let’s go for it.’

“Sam spoke first, and I spoke second, delivering the line about T-15sbeing made obsolete.

He reacted in that great trooper monotone, andthen we both performed a vocal for being taken down by rebels.

Theroom laughed.

We did a second take, and that was it.

The whole thingwent down in less than two minutes.

Stormtroopers: Beyond the Armor and [The picture above shows a] frame of two stormtroopers having a conversation about the obsolete T-15.

The exchange was intended to set up the conversation overheard during A New Hope regarding the new VT-16.

However, the Rogue One conversation identifies the previous model as a T-15, incorrectly calling out the letters as that would link the two references.

Stormtroopers: Beyond the Armor We can assume that the VT-15 is also a non-object that troopers complain about periodically (although I've heard that the T-17 is going to be a vast improvement).

I thought they said "C-15"; I assumed it had something to do with a Clone army and was a passing reference to the imperial army weaning itself off of clone troopers.

It's a nod to A New Hope, "You seen that new VT-16?""Yeah, some of the other guys were telling me about it.

They say it's… it's quite a thing to see…"―KE-829

and his partner aboard the first

Death StarThe BT-16 perimeter droid, also known as the VT-16, was a bulbous, spider-like droid.

I think that this is a reference to the non canon characters, Tag and Bink!

It also could be a reference to episode 4, when Tag and Bink are talking about the BT-16.

Question: At the beginning of the beach part of Rogue One, two stormtroopers are discussing something that they say is being rendered obsolete, followed by 'It was about time'.  It sounded like AT18, which is not a thing. It cannot be an AT-TE, as in Star Wars: Rebels it is obsolete already. What was it?

What do the stormtroopers describe as obsolete in Rogue One?

There is no real agreement as to what the stormtroopers believe to be obsolete at the beginning of Rogue One. However, it could be that they say "T-16", "T-15", "C-15" or "VT-16". There is also the suggestion that the line is a mistake.

It is uncertain what the reference is - it could be the T-16 skyhopper for example or it might even be nothing more than a misquote by the voice actors.

They might be saying "C-15" in reference to the Clone army.

It's a reference to the VT-16 in A New Hope.

It could be a reference to the characters Tag and Bink who talk about the BT-16.


Saying you're a Rebel scum with stolen information: you get tortured and killed 100% sure, and fail your mission 100% sure.

Lying your zhopa off and claiming (reasonably valid, technically speaking)

Diplomatic immunity: slight chance to delay Empire or even get out of this alive, meaning there's slightly less than 100% chance you get tortured and killed and fail your mission.

Second option seems infinitely more desirable, since a very slight chance is still much better than zero chance.

Pablo Hidalgo was asked this question on Twitter ; according to him, the mere fact of being on a consular ship is enough to give the crew diplomatic immunity: @HalfshellSeacon:

Why do Leia and Antilles pretend to not be rebels, when they just launched out of a rebel command ship?

It's an odd denial.

@pablohidalgo:

They're in a consular ship.

That gives 'em diplomatic immunity.

Or would've if not for Vader's insistence.

Vader, of course, has no respect for that sort of thing, and knows that those rules are going to be meaningless soon anyway, once the Imperial Senate is dismantled.

Diplomatic immunity still meant something Remember that, at that point, the Senate still was functioning, to the point that the Death Star had to be kept secret, so it was reasonable to assume that their diplomatic status would grant protection, evidenced by how Leia reprimands Vader.

It was briefly after those events that the Emperor disbanded the Senate and the Empire stopped pretending it was in any way democratic, turning to fear as a means of control.

IN any case, as others have pointed out, it's the same as someone caught red-handed committing a crime claiming to be innocent even on the face of overwhelming evidence, in order to force the authorities to undergo due process.

Presumably, unless they were spectacularly incompetent, the Tantive IV was not broadcasting its ID and/or diplomatic status when they fled from the battle, and only turned it on when they were clean away.

One Corellian Corvette looks pretty much like every other from the outside, so unless the Imperials could match specific identifying details to the ship that ran away from them at the end of Rogue One, technically as long as they keep insisting they're a Consular ship on a diplomatic mission, Vader would be obligated to honor their diplomatic immunity or the Senate would certainly frown at the Emperor in a most disappointed fashion and tell him such things are not acceptable, and if Darth Vader persists they will certainly write a strongly worded letter about it.

It's a diplomatic fig leaf, yes, but it's all they have --

well, all they think they have, because the Senate has been dissolved and the Emperor no longer even pretends to care about what they have to say, but they don't know that yet.

This has been addressed in the canon storybook Star Wars: From a Certain Point of View .

In short, the Tantive IV had the legal protection of the Senate.

Theoretically that should have been enough to grant them free passage, even if the Empire suspected them of espionage (in much the same way that real-world diplomats often hide behind diplomatic immunity).

Unfortunately for Leia, the urgency of the situation, the upcoming dissolution of the Senate and the fact that Vader had no qualms about destroying the Tantive IV meant that her legal immunity was pretty much useless.

“Surely it will not come to that,” said Corla Metonae, Tantive IV’schief petty officer and a long-serving retainer of the Organa royalhousehold.

“We’re still flying under a diplomatic flag.

The Empirewould not dare board us.”

Raymus considered that; technically it still held true.

The Tantive IVwas officially a consular ship that Leia used in the performance ofher duties as Alderaan’s representative in the Galactic Senate.

As adiplomat, she enjoyed special legal protections that meant not eventhe Imperial military could board, search, or in any way impede thefree passage of her ship without her express permission.

It was abroad and very convenient privilege that in the past had allowed herand Raymus to conduct acts of espionage and subterfuge right under theEmpire’s nose.

But now Raymus found himself doubting, given theapparent import of what had been stolen from Scarif, that it would beenough to protect them this time.

Star Wars:

From a Certain Point of View - "Raymus" by Gary Whitta

Refuge in Audacity.

"We were working backchannel negotiations to try and come to a peaceful solution to the problem these rebels were creating when the ship we were on suddenly took off with us aboard and they told us nothing, and there was a battle and it was horrible

but fortunately we made our escape when something happened!

And of course we were shooting back!

You started shooting at us!

We were within our rights as stated in the Treaty of Albuxijanumok to shoot back when faced with such aggression!

For all we knew, a crew of rebels had seized control of a star destroyer!"

Question: Given the ending of Rogue One...    ...it is obvious that the Imperials and Vader know that the Tantive IV ship was just engaged in a rebellion battle.   Therefore why does Captain Antilles, while getting choked by Darth Vader, say:   We intercepted no transmissions. ... This is a consular ship. We're on a diplomatic mission.   Why would he say such an obviously false lie? Especially when it is his last words?

Why does Captain Antilles in a New Hope say they're on a diplomatic mission?

Captain Antilles probably says these words for a number of reasons. The first and most obvious reason is that telling the truth would have mean a certain mission failure, torture and death, whereas lying might at least provide a very slim chance of some other outcome. Additionally, at this point in time, diplomatic immunity was still a meaningful concept and there was still protection provided to consular ships. Lying and pleading diplomatic immunity would have at least forced the authorities to follow due process.

There is an argument that technically their ship did enjoy diplomatic immunity so there was a chance of saving themselves that way, but also they had nothing to lose by claiming it - the alternative was death.

If not lying means certain death you may as well lie - however small your chance of being believed.

Diplomatic immunity was at that time still a widely respected principle so there was at least a chance of succeeding with the lie.

As there was nothing to identify their ship as a rebel ship they could plausibly claim to be diplomats.

Technically speaking their ship was under the legal protection of the Senate so they did have diplomatic immunity.


Yes, in "Journey to the Centre of the TARDIS".

After the Doctor and Clara have finally made their way all the way to the heart of the TARDIS, the Doctor pushes through a glowing crack in the wall to meet his earlier self from right back at the start of the episode.

From the transcript (emphasis mine): DOCTOR:

Oh, yes.

Big friendly button.

CLARA: You're lying.

DOCTOR:

Yep.

CLARA: To stop me freaking out? DOCTOR: Is it working?

CLARA:

Not so much.

(The future Doctor pushes through the crack.)

FUTURE DOCTOR:

Doctor, Doctor.

I'm from your future.

We haven't got long to reset time.

(He vanishes.

The grenade rolls across the floor to Clara.

She picks it up.)

As a bonus, there are also at least two more occasions in the show where Matt Smith has interacted with himself on-screen, although in-universe only one of these selves is the Doctor, the other being: in one case ("The Rebel Flesh"/"The Almost People"), a Ganger in the form of the Eleventh Doctor: in the other ("Nightmare in Silver"), a Cyber Planner taking over the Doctor's body and appearing inside his head as a Borgified version of him:

In the BBC Children in Need

special Space / Time , the 11 th Doctor speaks to a version of himself from mere moments into his future.

DOCTOR:

I'm setting up a controlled temporal implosion.

It's the only way to reset the TARDIS but unless I find exactly the right lever to control the implosion we're all gonna die.

AMY

: You don't know which lever?

DOCTOR:

No, but I'm about to find out.

(A second Doctor steps into the TARDIS through the main doors)

DOCTOR 2:

The wibbley lever!

DOCTOR:

The wibbley lever.

Thank you!

(The original Doctor throws the wibbley lever and steps into the TARDIS parked in the control room which then dematerialises)

You can watch both parts legally on YouTube, at least here in the UK.

The 11th Doctor meets himself in the episode

The Big Bang

From the plot synopsis The injured body of a future version of the Doctor appears and whispers something to his earlier self.

The whole plot of this episode can be seen in this awesome music video by Chameleon Circuit The Big Bang 2

The 3rd Doctor and Jo Grant interact with future versions of themselves in Episode 1 of Day of the Daleks.

Starts at about 3:25

(The Doctor goes underneath the console.

A moment later the doors to the lab open and a second Doctor and Jo are standing there.)

DOCTOR 2:

Yes, of course, I remember now.

Look, don't worry, my dear.

I know you're alarmed

but you needn't be.

DOCTOR:

Yes, well I think that should do it.

Why on Earth I never realised that.

(Then the Doctor sees himself standing there.)

DOCTOR:

Oh, no.

What are you doing here?

DOCTOR 2

Well, I'm not here.

Don't worry.

Well, that is, in a sense I am here, but you are not there.

Yes, well, it's a bit difficult to explain really.

DOCTOR:

This won't do at all.

We can't have two of us running about.

DOCTOR 2

: Yes, well don't worry.

It will all sort itself - (Flash, bang from the console and the duplicates vanish.)

JO: Doctor?

What happened?

DOCTOR:

Well, it's a very complicated thing, time, Jo.

Once you've begun tampering with it, the oddest things start happening.

JO:

But there was another you and another me.

Well, where've they gone?

DOCTOR:

Back into their own time stream, of course.

Or do I mean forward? -- transcript

Yes, this has happened a few times..

most notably in the Mini-Series Night and The Doctor

In episode 4 (Last Night), Doctor Who interacts with a second version of himself, and 3 different versions of River.

They dont solve a problem exactly, but it's the longest interaction between multiple Doctor Who's of the same incarnation I can remember.

And yes, Calling him "Doctor Who" is a joke.

And yes, calling it a joke makes it less funn..

never mind.

Night and The Doctor - Wiki

Not a direct interaction, but in Smith and Jones , the Doctor of the near relative-future sets up Martha's interactions with the Doctor of the relative-present.

Arguably, Blink is along those lines as well, as it's the Doctor's discovery of the future transcript that causes him to record the video that eventually gets transcribed in the first place.

If you were to stretch a point, it could be argued that in Logopolis, The Watcher (or Doctor 4.5) helped both his current self (4) and his future self (5).

As Nyssa says: "

The Watcher.

He was the Doctor all the time."

But like I said, it's probably stretching a point.

Question: Similar to  Has the Doctor ever observed himself, without revealing who he was?  but with a slight difference.  Has the Doctor ever worked with himself to solve a problem where both incarnations are the same?  There are numerous examples ("The Three Doctors", "The Five Doctors", etc) of different incarnations working together - but has he ever worked with himself?

Has the Doctor ever knowingly interacted with his current incarnation

Yes, it appears that in "Journey to the Centre of the TARDIS", the Doctor did indeed work with himself in his present carnation. There are also other instances of this during the Matt Smith series of Doctor Who.

Yes, there are number of times when the current Doctor interacts with himself, for example in "Journey to the Centre of the Tardis".

Yes, in "Journey to the Centre of the Tardis" and there are at least two occasions where Matt Smith interacts with himself.

Yes - the 3rd Doctor and Jo Grant interact with future versions of themselves in Episode 1 of Day of the Daleks.

Yes, in episode 4 (Last Night), Doctor Who interacts with a second version of himself.

Not a direct interaction, but in  Smith and Jones , the Doctor of the near relative-future sets up Martha's interactions with the Doctor of the relative-present.


Vader built his lightsaber within five years of his fall to the dark side Cross-referencing Wookieepedia's timeline of canon media and article on Anakin Skywalker , I believe the canon source which first depicts Vader after his fall to the dark side in Episode III is the novel Lords of the Sith .

The events of that novel occurred five years after Episode III, and the novel does mention that his lightsaber is red: The red line of Vader’s lightsaber flashed, deflecting the shots back at the Twi’lek, putting a dark hole in his chest and another in his face.

p. 108

No canon source appears to describe how he built it (or if it was given to him), but presumably he built it just as he built his lightsaber as a Jedi.

In Episode III, Revenge of the Sith , Anakin had a blue lightsaber.

In Episode IV, A New Hope , he has a red lightsaber.

Therefore, he acquired it in the 19 years between those two.

As Wookieepedia says here : Darth Vader's lightsaber was the personal lightsaber of Darth Vader, a Sith Lord.

He built the weapon some time after his fall to the Dark side of the Force at the end of the Clone Wars.

It replaced the one he lost during his duel with Obi-Wan Kenobi on Mustafar.

It is common for Force Users to build their own lightsabers; for example, Luke's new one in Episode VI.

In Legends , we have something more concrete.

In Dark Lord: The Rise of Darth Vader , which takes place directly after episode three, Vader creates his lightsaber.

he is seen here with the new lightsaber in Chapter 9:

In his quarters aboard the capital ship now under his personal command, Darth Vader, gloved and artificial right hand clamped on the hilt of his new lightsaber, knelt before a larger-than-life hologram of Emperor Palpatine.

And in Chapter 13: Sidious had provided the synthcrystal responsible for the crimson blade, along with his own lightsaber to serve as a model.

Vader, though, had no fondness for antiques, and while he could appreciate the handiwork that had gone into fashioning the inlaid, gently curved hilt of Sidious's lightsaber, he preferred a weapon with more ballast

So yes, he made the lightsaber in 19 BBY, directly after Episode III, in Legends.

In Legends, less than a month.

Bol Chatak was one of the few Jedi that managed to escape Order 66.

She was killed on Murkhana in a lightsaber duel with Vader, by which point he had his red saber.

This took place less than one month after the events of Episode III.

In Disney Canon, definitely within 5 years, possibly within a month As Null says, the earliest canon reference to Vader's saber is Lords of the Sith , which takes place 5 years after Episode III ends, though it is apparently mentioned in the novel Tarkin that Vader performed an execution for the Emperor on the planet Murkhana, so the event that occurred in Legends may still be true.

This cannot be proven definitively, however, because we aren't given any details.

I think it would be safe to assume that Vader had a red lightsaber before going on any missions, though.

Short answer: he probably built it very early on.

Perhaps as early as just prior to his final scene in RotS. (The one with Tarkin & the Death Star under construction in the background.)

Due to the way the scene is shot and edited it's not possible for it to be visible on screen if it is there, but the prop was certainly made for the movie and it's shown up in promotional photos of Hayden in the armor , so it seems reasonably likely it was part of his costume for that last scene.

As to when that scene takes place: it's tough to say exactly.

That final montage seems to cover at least a few days, if not weeks.

Assuming one is to take the order the scenes are presented as the literal chronological order of events (which may not actually be the case) then this scene falls right between Padme's funeral and Bail returning home to Alderaan with baby Leia.

The scene is somewhat revisited in the Rogue One tie-in novel Catalyst , albeit from Krennic's perspective

and though it doesn't give any more clues than the movie, the context of what's being said certainly gives the impression

this is still a matter of days--a week at the outside--after Order 66.

Indeed the Emperor is said to still be recovering from his encounter with Windu.

Mind you, even if they didn't end up using it in that scene, it still seems likely Vader would have built a new one ASAP.

At this point he would have built at least three others as Anakin

so he certainly knows what he's doing.

Resources shouldn't be a problem as Catalyst depicts the Empire is suddenly flush with spare kyber crystals in the wake of the Temple massacre.

(See the Ahsoka novel for how a reclaimed Jedi kyber can be turned into a red blade.)

First ever explanation (but ambiguously canon in Legends)

The other answers explain the Legends and Disney canon explanations, but I'd also like to throw out the first ever explanation (even if it was ambiguously canon even at the time), which was in the Star Wars Episode III: Revenge of the Sith video game .

This came out on May 4, 2005 which was released 11 days before the movie.

In an alternate ending, Anakin kills Obi-Wan Kenobi in their duel.

Emperor Palpatine arrives on Mustafar and hands him a new red lightsaber, then Anakin kills him with it.

As we can see, the Emperor already had the red lightsaber ready to give to Vader.

It stands to reason that Palpatine gave it to Vader as soon as he had recovered enough to use it.

Granted, this relies on whether Palpatine having the lightsaber is still C-canon (according to the Legends classifications system) despite the ending itself being non-canon.

Question: Between Episodes III and IV, when and how did Darth Vader obtain/construct his red lightsaber?

When did Darth Vader get his red lightsaber?

There is not enough detail available to say with confidence when Darth Vader acquired his red lightsaber, although some estimates suggest that he acquired it less than a month after Episode III and at least within five yeras of falling to the Dark Side. However, it is generally considered that he probably built it or received it from the Emperor Palpatine.

There is no definite explanation provided in the canon of how Vader made the lightsaber but he clearly made or acquired it between Episode III and IV.

Vader built his lightsaber within 5 years of his fall to the Dark Side. There is no canon explanation of how he did it.

Vader acquired the lightsaber in the 19 years between Episode III (when Anikin had a blue one) and Episode IV (when Vader had the red one).

Legends says Vader built it in less than a month, after the events in Episode III.

He built it early on, possibly prior to his final scene in RotS.

The first explanation is in the Episode III video game where Anakin kills Kenobi in an alternative ending.


As the question is not limited to humans, Leaf is the oldest.

According to the books she's at least two hundred years old.

“Tell us what you saw.”

From far away Leaf looked almost a girl, no older than Bran or one of his sisters, but close at hand she seemed far older.

She claimed to have seen two hundred years.

unless you've read as far as A Dance With Dragons : Brynden Rivers aka

aka the three-eyed crow is older than Maester Aemon when Bran finds him still alive but embedded in a weirwood tree's roots.

He was born in 175AC, 23 years before Maester Aemon, so he is about 125 years old during the events of the books.

The three-eyed crow is confirmed as Brynden Rivers in A Dance With Dragons when he says: “I wore many names when I was quick, but even I once had a mother, and the name she gave me at her breast was Brynden.”

In A Feast For Crows at the end of the book when Samwell reaches the Citadel Maester Aemon is described as the oldest man in Westeros at 102 years old.

He had been the thirteenth man to lead the Night's Watch, she said; a warrior who knew no fear. '

And that was the fault in him,' she would add, 'for all men must know fear.

- A Storm of Swords, Chapter 56, Bran IV

The Night's Watch was founded over 8,000 years ago after the Long Night.

If we add a bit of reasonable bit speculation and historically it seems the longest a Lord Commander served was 60 years ... means that he served ~780 years after the founding of the Watch, which would make him over 7,000 years old Although GRRM himself doesn't really buy that...

As for the Night's King (the form I prefer), in the books he is a legendary figure, akin to Lann the Clever and Brandon the Builder, and no more likely to have survived to the present day than they have.

Probably Melisandre.

According to David Benioff, one of the showrunners of Game of Thrones , Melisandre is "several centuries old".

In HBO's feature Game of Thrones Season 6: Inside the Episode #1 , he says this information comes from conversations with George R. R. Martin, so presumably this is the case in the books as well.

Several centuries" is vague, but clearly makes her older than characters like Master Aemon and Bloodraven, and probably also Leaf, who claims to be 200 years old (and "two" is not "several" in my book).

Although it's not canon information, Melisandre's actor Carice van Houten has claimed in interviews that Melisandre is 200–300 years old and 400 years old .

Oh my sweet summer children...

The Cannibal img src Was the oldest and one of the largest of dragons at the time of the Dance of the Dragons ( 129 - 131 AC ).

[It was]

A wild dragon, a scavenger and killer of hatchlings, never tamed and vanished at war’s end .

The Cannibal is most likely still alive and roaming freely in or around the Shadow Lands .

Having roots likely around 114BC [1] , If The Cannibal is still alive, then it would be a minimum of 414 years old , making it the oldest living character of this world [2] .

Honourable Mentions Old Nan Age: unknown, likely over 100 as she is

Hodor's great-grand-mother Maggy

The Frog

Age: Unknown, likely a nonagenarian or older The Weirnet

The "Weirnet" is a network of Weirwood trees which are all somehow connected.

This allows the likes of Bran and Bloodraven to "connect" to it and witness events from the past, present and future.

Being that the weirwoods are alive and growing, I would put this one down as a technicality.

Age

: Timeless; weirwoods are said to grow forever if left undisturbed [1]

The World of Ice and Fire [2]

I don't count the undead (which includes Others and Wights) in this calculation

Depending on how you measure age and life, the answer to both could be Daenerys' 3 dragons, which were laid as eggs 'eons ago', and were since turned to stone.

From what we know of Dragon's physiology , hatching a dragon egg requires both the physical development in the egg that normal lizards require, as well as some variation of magic, ritual etc.

Whether the Dragon is 'alive' from the moment that it has physically grown enough in the egg that it has the potential to hatch, or if it only becomes alive when it does hatch is unknown, and mayby unknowable.

In the T.V. Show Game of Thrones in season 6 episode 5

we see a scene where Leaf plunges a shard of Dragonglass into a man's heart.

When Bran awakes from this vision he says, "It was you.

You made the white walkers."

Leaf then says, "We were at war.

We were being slaughtered.

Our sacred trees cut down.

We needed to defend ourselves," "From whom?"

"From you, from men." So the war against the first men happened thousands of years ago.

Now if this white walker they created was the first white walker that means that this happened before the Long Night making Leaf at least 8000 years old.

Besides Leaf there is another character 100+ years old.

That would be Brynden Rivers.

If he was born around 175 AC that would make him 125 years old though he stopped aging at the age of 77.

Question: I know that a long life is not usual in the world in which  A Song of Ice and Fire  is set. That brings to me some questions:  Who is the oldest character that lives during (a part of) the books?  Who is the oldest character in Westeros' history?

Who are the oldest characters in A Song of Ice and Fire?

There is no clear correct answer to this question. However, potential contenders for the oldest character in A Song of Ice and Fire include Leaf, The Night's King, Melisandre and The Cannibal. The oldest character in Westeros is named as Maester Aemon in A Feast for Crows.

Views vary, but the main contenders are Leaf (as we are not limited to humans) at 200 years, Maester Aemon at 102, Melisandre at several centuries, Cannibal at 414, Daenerys's dragons at 'aeons' and the Nights King at possibly over 7,000 years old.

Leaf is the oldest (as we are not limited by the question to humans) at around 200 years.

The oldest man is Maester Aemon, who is 102 years old.

The Night's King Over Nine may have been over 7,000 years old, depending on the calculations.

Possibly Melisandre, as she is described as being 'several centuries old' which makes her older than Leaf.

Excluding the undead such as the Wights, the Cannibal would be the oldest living character - if still alive - with an age of at least 414 years.

Daenerys' 3 dragons can be regarded as the oldest if we take age to include time spent as an egg, since they were laid 'aeons ago'.


The assumption in the question is mistaken.

As @Mithrandir already linked above, it's a common assumption of adult readers that Hobbes couldn't possibly be real but that's just not how the actual comic works .

Watterson intentionally left the entire issue unresolvable, with strips like this where Hobbes should need to be real for Calvin to be in the situation he's in.

The shift between how Calvin and his parents see the world is very real and part of what the comic explores, but Watterson didn't feel the parents were right and Calvin was wrong .

No.

Calvin's parents mostly play along with his belief Hobbes is real.

But when Susie directly points out that Hobbes is a stuffed toy, Calvin simply ignores her: In the very last panel of the comic, we see Calvin as convinced as ever that Hobbes is a real tiger:

What makes you think that he's not real?

First, consider what you mean by "real.

" If you mean "could you put a video camera there and record Hobbes doing the things that the comic strip has him doing with Calvin?

", that's deliberately left ambiguous in the comic strips.

In fact, even in a strip where Calvin takes photographs of Hobbes, Calvin and his dad just see the pictures differently, so it resolves nothing

- it's not clear what the pictures "really" look like.

I'm not convinced that the "video-camera approach" is the best way to view this, though.

Try to view it through the characters' POV.

From Calvin's POV,

yeah, he's real.

From the other characters' POV, he's a stuffed tiger.

I don't think that it's really important (or provable from the comic strip)

which one is "correct" in the video camera sense.

scifi.stackexchange.com/users/77587/EJoshuaS - Reinstate Monica

As far as I understood when I read Calvin and Hobbes, the situations Calvin finds himself are always ambiguous.

One could choose to believe that Calvin just has a high imagination in his role play with his stuffed toy or one could believe that Hobbes is some kind of magical toy that comes to life only for Calvin and is a stuffed toy to the rest of them.

something like Perry in "Phineas and Ferb" (just the concept not the stuffed part).

And I always read these comics from the second point of view because it makes it that much more fun.

Especially since we never hear dialogues from Hobbes when there are other people around.

All his interactions are mostly done when they are alone.

I'd argue yes, in this strip (May 20, 1986):

Question: In the comic strip  Calvin and Hobbes , was there any moment where Calvin realised that Hobbes wasn't real?

Did Calvin ever realise that Hobbes was not real?

It is something of an assumption to say that Hobbes is not real, and therefore, this question may indeed be mistaken. However, there is no indication at any point in the comic series that Calvin realises that Hobbes isn't a real tiger.

The question misses the point because the stories are to some extent about what is real and how POV affects this and no final answer is provided.

The question makes an incorrect assumption that Hobbes is not real - whereas the comic itself never makes this clear, and that is the point of it.

No - his parents mostly play along with it but when Susie points out Hobbes is a stuffed toy Calvin ignores her.

It depends on what you mean by real, as this is a product of a character's POV.

The situations are always ambiguous so it is never clear what is real and what is not.


A pretty compelling one is this strip, where Calvin had no opportunity to take the cookies without Susie noticing: I also find it interesting that "real" Hobbes appears in the second pane.

Then there's this one, where Calvin would probably have some serious difficulty getting that high up a tree while holding a water balloon on his own, but more convincingly, Calvin is shown leaving the water balloon at the base of the tree before he climbs:

There's also a few where it's unlikely Calvin did something.

There's the tied up one in the OP, for example.

There's also this one, where Hobbes probably stole a piece of cake:

There's this one, too, which, assuming it happened as shown, would be very strange if Hobbes wasn't involved: There's some honorable mentions as well, although I didn't feel they were strong enough to explicitly mention above.

They hint at things done by Hobbes to Calvin but one could imagine Calvin doing them to himself:

Hobbes knocking Calvin backwards at the door Hobbes throwing a water balloon at Calvin, and dragging a full kiddie pool Hobbes makes a clay tiger at the same time that Calvin makes a clay bowl, and Hobbes' is much higher quality Hobbes carries Calvin on his shoulder and puts him in a tree, then tickles his feet Hobbes places Calvin in a large rain barrel, and Calvin appears to not be happy about it

There's a lot of other examples along these lines if you look around

( this is a good source , for example).

But Watterson left it intentionally vague, so as with all questions related to Hobbes' existence, we can never be 100% sure.

No.

In the examples provided, as well as every other strip that I can find, there'snothing inconsistent with a young child who has a very vivid imagination.

My personal opinion is that when Hobbes does many of the things that Calvin credits(or blames) him for, Calvin is actually pretending that he's Hobbes.

The issue in the comic strips is that, when we see the "living" Hobbes, we'reeither seeing the other reality that nobody else sees (in which case Hobbesreally is alive and is Calvin's active co-conspirator), or we're inside Calvin's imagination,in which case, how much of the rest of the scene is also his imagination?

Note that the fact that it's his imagination doesn't make it any less real, but it's a subjective reality, rather than an objective one.

We don't know that Calvin didn't have the opportunity to take the cookies; hecould just be very very sneaky.

I've watched children, while pretending, do things equally as elaborate to setup a simple scenario and then maintain that their imaginary friend helped them,they "flew up here," or given any of a dozen other explanations.

Again - ifHobbes is real, then he helped.

If Hobbes is pretend, then what else ispretend in the scene?

Simple deflection.

Who's to say that Calvin didn't sneak in for a piece ofcake earlier and then pretend (even to himself)

that Hobbes did it.

Somebody else commented that this could just be an elaborate explanation fora wipeout.

Makes sense.

Rationalization for falling down, or what he imagined (wished?)

would happento Suzy.

In the following cartoon strip Hobbes presses the button on the outside of Calvin's Duplicator .

Given the position of the button, there's simply no way that Calvin could have pushed it himself, from inside the machine.

Eating Tommy Chesnutt: Calvin could not have eaten his classmate.

Yes.

Hobbes unlocks the front door of the house and leaves without Calvin's mom noticing.

Notice

the last panel - Calvin sneaks home from school and does not enter the house, as evidenced that his mother has not yet noticed him.

It is strongly implied from the wording as well that Calvin has just arrived back from school and has not yet entered the house.

Yet, HOBBES IS OUTSIDE .

Question: So  this question  got me thinking that, except for pure Calvin fantasy (i.e. Spaceman Spiff, where nothing is real), is there ever a comic where Calvin claims Hobbes did something and Calvin could not have possibly performed himself? This one comes close, but Calvin could have tied himself up   Note that we don't have to see Hobbes having done it, just that it would have very difficult or impossible for Calvin to have done it.

Does Hobbes ever do anything that Calvin himself could not do?

There are few examples of instances in which Hobbes has done something which Calvin himself could not do. The OP's example of Calvin being tied up is one such example. Other examples include eating Tommy Chesnutt and Hobbes unlocking the front door without Calvin's mum noticing. Finally, there is the instance in which Hobbes presses a button on the outside of Calvin's duplicator.

There are many strips where it can appear certain that Hobbes is doing things that Calvin could not have done - but Watterson always leaves an element of uncertainty so the reader can never be 100% sure.

Here are a number of strips providing compelling  evidence that Calvin is not doing the stuff that he says Hobbes does. At the same time, Watterson is careful never to provide 100% evidence - there is always an element of uncertainty.

All of the strips can be explained as the product of a child's imagination - Watterson is simply playing with the POV.

In the cartoon presented here Hobbes is pressing a button which would be physically impossible for Calvin to press due to its position.

Calvin could not have eaten his classmate Tommy Chesnutt.

Yes - in a strip where Hobbes leaves the house by himself before Calvin entered after returning from school.


Although the character isn't named in the episode, The Star Trek Voyager Companion (billed as the "official companion to Star Trek: Voyager" ) identifies the remains as belonging to Ensign Hogan , the maquis crewman who was killed in a cave in VOY: Basics You can see the similarity in the caves in the shots below.

The remains were those of Maquis crewman Hogan , a recurring character in the second and third seasons, who died in the third season premier ( "Basics, Part 2" ).

The Kazon had stranded Voyager's crew on a primitive planet, and Hogan fell prey to a large animal while investigating a cave.

Due to the danger posed by the animal, Hogan's crewmates were unable to retrieve his remains.

Source: Hogan

(actor Simon Billig )

| Memory Alpha

That unfortunate crewman was killed by an critter while exploring the surroundings, when the Kazon left the crew of the Voyager on a deserted planet to die.

It happened in the first episode of season three.

I agree that the remains were supposed to be Hogan, but the only issue I see is that Hogan's uniform was retrieved in Basics part 2 and used by Chakotay to make a water filtration system, including his rank insignia.

In basics part 2 an unnamed character in a blue uniform was pulled off a rock and part eaten by the same creature, before they blocked the cave up so the creature would slowly starve to death.. perhaps it could have been his remains?

Question: In the first act of  Voyager  episode  "Distant Origin" , we see two Voth archaeologists recover the human skeletal remains of a Voyager crew member in a cave on an M-class planet.   Strangely, the remains were never identified in the episode. Are they any clues in prior episodes how a Voyager crew member died on this planet? And why his corpse was not retrieved?

Who was the dead Voyager crew member discovered by the two Voth archaeologists?

The character in question isn't named in the episode but is named in the Star Trek Voyager Companion as Ensign Hogan. Hogan feel prey to a large animal while investigating a cave and due to the threat posed by the animal, his crew mates were unable to retrieve his remains.

The skeleton was most probably the remains of Ensign Hogan who fell prey to a large creature when exploring the cave.

The skeleton was the remains of Ensign Hogan who fell prey to a large creature when exploring the cave.

The skeleton belonged to an unnamed character in a blue uniform who was eaten by the same creature.


Hugo Hercules was featured in a comic that ran for five months between 1902 and 1903.

While specifically described as having super strength, in one comic he was able to pull a line of train cars at the same speed as a train.

From Wikipedia

A good-natured man endowed with superhuman strength, the character of Hugo wandered about town, helping people with their problems and shocking them with his surprising displays of power.

He was so strong he could pick up an elephant, kick a house like a football, wield an artillery cannon like a handgun, and lift a locomotive engine off the tracks and pull its cargo behind him at train speeds.

I'll put forward Prof. Gibberne of H.G. Wells's 1901

The New Accelerator until I'm certain

how "heroic" you're wanting submissions.

The story addresses an elixir, invented by a Prof. Gibberne, that accelerates all of an individual's physiological and cognitive processes by some orders of magnitude, such that although the individual perceives no change in themselves, the external world appears almost frozen into immobility and only the motion of most rapidly moving objects - such as the tip of a cracked whip - can be perceived.

The exploration of the consequences of this is incomplete; for example, the inventor and his companion find that while under the influence of the elixir they can easily singe their clothing from the heat produced by friction against the air as they walk, such is the rapidity of their motion; but this same air friction would render it impossible to breathe at a correspondingly accelerated rate, and this difficulty is ignored.

For an earlier literary hero who admittedly toes the border of mythology, Hiawatha from Henry Wadsworth Longfellow's famous Song of Hiawatha published in 1855: Swift of foot was Hiawatha

He could shoot an arrow from him And run forward with such fleetness, That the arrow fell behind him!

For the first actual comics superhero, I'm going to suggest

The Whizzer who debuted in USA Comics #1 (Aug. 1941), published by Timely Comics.

Robert L. Frank was born in St. Louis, Missouri.

The origin of the Golden Age character begins while Robert Frank is on a trip to Africa with his father, Dr. Emil Frank, where Robert is bitten by a cobra.

Dr. Frank saves Robert by a transfusion of mongoose blood, and soon discovers that his son has developed super-speed.

Frank then decides to fight crime and eventually accepts the offer of Invaders member Bucky, who forms the superhero team the Liberty Legion to rescue the other Invaders, who have been brainwashed by the villain the Red Skull.

When the Liberty Legion and Invaders eventually disband after World War II, the Whizzer joins the newly formed All-Winners Squad.

The Whizzer afterward spent some years battling alcoholism and depression, and was, for some time, homeless in the Bowery section of Manhattan.

He also works as a nuclear laboratory technician.

As we are including novels, I propose the 1785 book " Baron Munchausen's Narrative of his Marvellous Travels and Campaigns in Russia ".

One of the cohorts and friends described therein is Berthold, the world's fastest runner .

https://en.wikipedia.org/wiki/Baron_Munchausen https://en.wikipedia.org/wiki/The_Adventures_of_Baron_Munchausen

Question: Who was the first super hero with super-speed powers in comics?  Plus question: Any prior hero from Pulp magazines or books with super-speed?  Mythological species not included.

Who was the first super hero with super-speed powers in comics?

Whilst it is not certain to be the first super hero with super-speed powers, it appears that the likely answer is Hugo Hercules, which was a comic that ran for five months in 1902 and 1903.

The earliers one appears to be Hugo Hercules who ran in a comic from 1902 to 1903 and who had super strength and super speed.

Hugo Hercules ran in a comic from 1902 to 1903 and had super strength and super speed.

The Whizzer debuted in 1941 and had super speed.


The two examples Tyrion cites:

The Nights Watch

- They choose by popular vote on those who wants to be the next leader.

The Ironborne - (not 100% on this)

They choose via a Moot on those who want to be a leader.

Essentially Tyrion is saying you can't have children

but you could either pick a successor or let the people decide.

As to why he thinks it's important, he explains that: Your Grace, I saw hundreds of arrows fly towards you when you fought on Blackwater Rush, and

I saw hundred of arrows miss.

But any one of them could have found your heart.

Essentially if you keep flying into danger at some point danger will come your way.

Without a successor in place this whole thing will have been for nothing.

As @MikeScott mentions in a comment: He may also be trying to suggest to Dany that it's irresponsible of her to put herself in danger, since in fact there is no potential successor who can control her dragons (as far as anyone knows at this point), regardless of how they are chosen.

And without the dragons, the whole enterprise will immediately collapse.

Tyrion never outright states it

but it is certainly implied though I don't think it is his main reason for bringing it up.

As @Kepotx says in a comment: Also, if she win, but die without successor, that mean no queen, and new war for the throne.

This fact is not in her favour if she want to bring lot of people on her side.

If she is to gain more support having an available successor will help.

However, it doesn't seem to be common knowledge that Dany can't have children, and it's even debatable if she can or not, so this might not be the main motive behind Tyrion's comment.

Tyrion is addressing both the immediate and future need for a successor.

In the short term, if she is going to expose herself by using and riding the dragons, there needs to be a clear successor to take up the reins

should she die, otherwise everything falls apart.

In the long term, it's important for the people to know that there is a stable line of succession, whether it be by birthright, or some other means.

Imagine that Dany does win the Iron Throne.

Great, right?

But what happens when Dany dies?

Presumably, she's not immortal.

When Dany shuffles off this mortal coil without a successor, we're right back to where we are now!

Various parties will be trying to scheme or force their way into power.

Look to real life history for examples of what happens when the line of succession is weak, or unclear.

Entire empires built by strong, charismatic individuals have been crippled or destroyed on their death because of this.

Look at the empires of Alexander, or Genghis.

Tyrion is advising Dany to avoid that fate.

At present, he's speaking to her about the short term ramifications, but you can bet he's thinking very hard about the long term as well.

In story, it's because she's risking everything by placing herself in danger, as others have suggested, so I won't labour the point on that.

Dramatically, however, it's to foreshadow the events that followed, lending the later events a hint of cosmic irony .

Indeed, by doing as she did, 1 she appears to have greatly increased the risks everyone faces by losing a dragon to the night king -- and the situation could have been far worse ; Drogon might easily have been hit and she could have been killed -- in hindsight lending Tyrion's words some prophetic weight.

(the spoiler is pretty major, don't say you weren't warned)

He saw Daenerys fighting.

So he believed that she might die.

Once she dies, every thing will go in vain.

And that's why he didn't want her to go beyond the wall.

Besides, Daenerys can't be a mother, her dragons are her only sons.

So Tyrion thinks that she has to choose a successor.

Even beyond the obvious facts that, herself being from a family of feudal rulers (re-)conquering a feudal realm, where succession is always massively important (which others have already touched upon), at this point it's also a simple military matter that would be just as important today.

You are fighting a war, it is absolutely paramount that there is always a quick and if possible simple answer to the question of "who is in command?

", if there isn't you can watch your forces crumble in disarray and confusion.

So far, this hasn't been a big problem, Dany has never been in a position of immediate danger during the battles that her armies have fought, but with her riding Drogon into battle, that has changed, so the question of "if something happens to you, who is in command?" becomes vital.

Especially considering that Tyrion has seen a lot of people in command die or get taken out during the last years, and he has seen the chaos that often follows, so it's only naturally for him to try and make sure things remain as stable as possible if something were to happen to Dany.

Question: In the episode Beyond the Wall, Dany and Tyrion had a lengthly conversation about successors. And Tyrion said to Dany:   You say you can't have children.  But there are other ways of choosing a successor.  The Night's Watch has one method, The Iron born folk, although many  flaws have another.   Why did he think it was so important to remind Dany of this now?What are the methods he is talking about exactly besides having children?

Why does Tyrion think a successor is so important at this point in Season 7, episode 6?

The clearest reason that Tyrion thinks that a successor is important at this point in the series is because he believes that Daenerys might die.

Daenerys can choose a successor as a way to avoid the chaos that will otherwise threaten if she dies childless
