Meta Battle Subway PokeBase - Pokemon Q&A

Have EV values changed over the Generations of Pokemon?

6 votes

In general, a pokemon that has not evolve yeilds one ev (like charmander), a pokemon that has evolved yeilds two (like charmeleon), and a pokemon that has evolved twice yeild three (like charizard). There certainly are exeptions, but this is just a general rule of thumb. Today I was EV training a ralts on Emerald and was fighting Roselia, which according to the ev chart yeilds two sp attack evs. However, I realized that budew was added in gIV, so if Roselia followed that general rule, it originally would have only had one ev yeild. Of course, it's possible that I'm majorly overthinking this and Roselia might have been one of those pokemon that didn't evolve and gives two evs anyways like audino, but I don't want to mess up how many evs my pokemon get.

So, bottom line of this question is have ev yeilds changed over the generations? If so, what specific changes have been made? Thanks.

Generation I
The EV system was introduced in Generation I, where it was also called Stat Experience or Stat Exp.
EVs are factored into the Pokémon's stats when it levels up. Additionally, EVs are calculated into stats when a Pokémon is taken from Bill's PC; this is called the box trick. A Pokémon which reaches level 100 can continue to accrue EVs up to the maximum of 65535 in each stat, and use the box trick to have those EVs factored in.
Vitamins add 2560 to one stat's EV, but cannot raise a stat above 25600. Unlike the Exp. Share in later games, the Exp. All did not share EVs.

Generation II:
EVs behave the same in Generation II as they did in Generation I. Both Special Attack and Special Defense share the EV for Special to maintain compatibility. The box trick can still be used.
Generation II introduced the Pokérus, a rare status ailment which doubles the effort points gained in battle.

Generation III:Generation III completely overhauls the effort value structure. Effort points are now separate values from the base stats. Defeated Pokémon give out 1, 2 or 3 effort points to a particular stat, depending on species (see list of Pokémon by effort value yield). However, in battles that do not give any experience (such as in the Battle Tower or if the Pokémon is level 100), Pokémon will not gain any effort points. At level 100, a Pokémon's stats will be one stat point higher in a specific stat for every four effort points gained in that stat. For every Pokémon that has gained Effort Points in battle, stats will be recalculated upon leveling up, except for Deoxys, whose stats will be recalculated after every battle instead.
Pokémon are limited to a total of 255 effort points per stat, and 510 effort points in total. However, at level 100, since a stat increases by 1 point for every 4 effort points, only 252 effort points are required to maximize a stat.
Vitamins add 10 effort points, but cannot raise a stat above 100, or raise the total above 510. A new vitamin, Zinc, enhances Special Defense.
A new held item, the Macho Brace, doubles the effort points gained in battle. In combination with the Pokérus, a Pokémon can gain four times the normal effort points. However, the effects of the item do not transfer to a Pokémon holding an Exp. Share.
In Pokémon Emerald, certain Berries that were previously only used to make Pokéblocks can decrease certain effort values by 10 effort points, while increasing the happiness of the Pokémon they were used on.

Generation IV:
Most of the Generation IV EV system remains unchanged from Generation III, however, EV-reducing berries will reduce Effort Points to 100 if the current Effort Points for the stat were above 100.

Generation V:
In Generation V, most of the EV system remains unchanged from Generation III and IV. EV-reducing berries no longer reduce Effort Points to 100 if the points were above 100; instead, only 10 EVs are deducted. Pokémon can now gain effort values from battling even at Level 100, and stats are recalculated at the end of every battle instead of only after leveling up, much like Deoxys in the Generation III games.

As for Roselia,it always had 2 EVs in Sp.atk.

EV yields haven't changed over generations since Gen III.
Some base pokémon (like Roselia was) give 2 EVs. And from Gen IV on, Roselia is a pokemon that evolved once.
