Individual Values (IVs) are hidden stats (0-31) for each Pokémon, determining their potential. Effort Values (EVs) are gained by battling specific Pokémon, boosting particular stats. Each Pokémon can have a maximum of 510 EVs, with 252 in a single stat. Natures provide a 10% boost to one stat and a 10% reduction to another (e.g., Adamant boosts Attack, lowers Special Attack). Understanding these mechanics is crucial for competitive team building. You can check IVs post-game and use items like Mints and Feathers to optimize them.
