As a Pokémon expert, I can tell you that in the context of the Pokémon games, an EV stands for Effort Value. Effort Values are hidden points that Pokémon gain from battling with or catching other Pokémon. These points contribute to the Pokémon's overall stats, such as HP, Attack, Defense, Special Attack, Special Defense, and Speed.

Effort Values are gained as follows:
- A Pokémon gains 1 EV point in a particular stat for every wild or opposing Pokémon it defeats in battle.
- Defeating a Pokémon holding a specific type of item (like a Power item) can provide additional EV points in a specific stat.
- There are also items that can be used to increase a Pokémon's EVs without battling, such as vitamins.

It's important to note that each Pokémon can have a maximum of 510 total EV points, and no more than 252 EV points in a single stat. Once a Pokémon reaches its maximum EVs, it can no longer earn additional points.

When a Pok��mon is defeated, its base stats are converted to effort points and then added to the EVs. For example, defeating a Mew grants 100 effort points to each EV. (Defeating 656 Mew, therefore, will give a Pok��mon maximum EVs in each stat.) EVs are factored into the Pok��mon's stats when it levels up.read more >>
