Unnamed artificial lifeforms
The following is a list of unnamed artificial lifeforms.

A500 units 

Multiple A500-type androids were working as laborers at Utopia Planitia Fleet Yards in 2385. Among those present were F5, F7, and F8. ()

Aia artificial lifeforms 
At some point prior to the 24th century, the natives of Aia created artificial lifeforms which eventually turned against their creators, presumably driving them to extinction. These synthetics created the Admonition as a message for other synthetic lifeforms to find, telling them how to achieve first contact with an extra-galactic synthetic civilization greater than themselves. This extra-galactic civilization was said to be willing to help "free" all synthetics from their organic "oppressors", including possibly through genocidal means. In 2399, Soji Asha attempted to summon this extra-galactic civilization using the signal beacon at Coppelius Station. However, Jean-Luc Picard soon made her realize the unnecessary severity of her actions, and she deactivated the beacon. ()

Ard'rian McKenzie's robots 
In 2366, several robots (many of which were in pieces) could be seen throughout the home of Ard'rian McKenzie on the planet Tau Cygna V. ()

Banea artificial lifeform 
The Banea used an artificial lifeform as a host for implanting memory engrams in the minds of convicted murderers. This was part of a punishment which caused the perpetrator to periodically relive the event from the point of view of the victim. ()

Coppelius butterflies 
By 2399, there were synthetic butterflies present in the settlement on the planet Coppelius. They had been created by Dr. Noonian Soong's son, Dr. Altan Inigo Soong, who had made them simply because he missed seeing butterflies. Their wings could change color.

Within the quantum simulation where his rebuilt consciousness resided, Data used the image of a Coppelius butterfly to illustrate that the finite nature of Human life helped define and give it meaning, stating that "a butterfly that lives forever... is really not a butterfly at all." ()

Corrupted isolinear core 
In 2380, Ensign  of the  inadvertently created artificial life in the form of a corrupted isolinear core, which came into being when Fletcher attempted to make himself smarter by interfacing with an isolinear core from the Cerritos. However, the core ended up being corrupted by his brainwaves, eventually causing it to spring to life and attach various mechanical components to itself. The corrupted core was ultimately ejected into space via an airlock by Ensigns Brad Boimler and Beckett Mariner, where it inadvertently aided the Cerritos by incapacitating an attacking Drookmani ship. ()

Daystrom Institute evil computers 

Almost immediately after AGIMUS was dropped off at the Daystrom Institute's Self-Aware Megalomaniacal Computer Storage in 2381, he began arguing with the multitude of evil computers who were stored alongside him. ()

Dr. Graves' robots

Humanoid robot 

This rather odd-looking humanoid robot, built by Dr. Ira Graves, was present in his home on Gravesworld in 2365. ()

Robotic dog 

This robotic dog, built by Dr. Ira Graves, was present in his home on Gravesworld in 2365. ()

Shore Leave Planet robots

Japanese pilot 

In 2267, this highly sophisticated robot of a Japanese pilot made a strafing run over the Shore Leave Planet in a Japanese Zero. This was one of the several experiences had by the crew of the  created by the planet's master computer. ()

Samurai warrior 

In 2267, this highly sophisticated robot of a samurai warrior was created by the Shore Leave Planet's master computer from the imagination of Hikaru Sulu, and was brought to life by devices on the planet.

An antenna on the planet would scan a person's mind and derive creations from their thoughts. This happened to Sulu when he was on shore leave on the planet. The samurai attacked Sulu and engaged him in a series of bouts. ()

Horse 

In 2267, the Black Knight was seen riding this robotic horse, both of whom had been created by the Shore Leave Planet's master computer. ()

Rigel chorus girls 

In 2267, these two highly sophisticated robots of Rigel chorus girls were created from the imagination of Dr. Leonard McCoy on the Shore Leave Planet in the Omicron Delta region. They were based on two performers from a cabaret chorus line whom Dr. McCoy had previously encountered on Rigel II. ()

Giant cat 

This robot resembling a giant cat was encountered by a landing party from the Enterprise upon its return to the Shore Leave Planet in 2269. ()

Knaves 

In 2269, the Queen of Hearts and several of her knaves were replicated as robots by the Shore Leave Planet's master computer, and appeared to Leonard McCoy with the intent of beheading him. ()

Pterodactyls 

These robots resembling pterodactyls were encountered by a landing party from the Enterprise upon its return to the Shore Leave Planet in 2269. They were created due to a malfunction in the planet's master computer, as no one in the landing party had thought about pterodactyls. ()

Two-headed dragon 

This robot resembling a two-headed dragon chased after Hikaru Sulu and Leonard McCoy upon their return to the Shore Leave Planet in 2269. The robot was very large, and capable of breathing fire. After the planet's master computer agreed to stop attacking the crew of the Enterprise, the dragon could be seen on  a viewscreen, having a picnic with Sulu, McCoy, , and the White Rabbit. ()

Soong-type prototypes 
These two prototype Soong-type androids, along with B-4, had failed sometime prior to 2338. Noonian Soong and his wife Juliana considered them their children, and were saddened upon losing them. Lieutenant Commander Data was unaware of their existence until Juliana Tainer told him about them in 2370. ()
