Here's how EVs work:
* Earned through battles: Pokémon gain EVs by battling other Pokémon. Different Pokémon species give different EVs depending on their stats.
* Limited to 252 per stat: You can only gain up to 252 EVs in any single stat for a Pokémon.
* Can be reset: You can reset EV points with vitamins, EV-reducing berries, or a special item called the "Macho Brace".
The Pokéwalker serves a different purpose in the Pokémon games:
* Catching Pokémon: The Pokéwalker allows you to catch wild Pokémon in a virtual world.
* Training: The Pokémon you catch on the Pokéwalker can gain experience points (EXP) and learn new moves.
* Connecting to your game: You can transfer Pokémon back and forth between the Pokéwalker and your game, allowing you to use them in battles and contests.
In summary, the Pokéwalker lets you catch new Pokémon and train them, but it does not affect their EV points. You'll need to battle other Pokémon to gain EVs and boost your Pokémon's stats.
