Beyond Natures, Individual Values (IVs) and Effort Values (EVs) are crucial for competitive Pokémon. IVs are hidden stats determined when a Pokémon is generated, ranging from 0-31 for each stat. EVs are gained by defeating specific Pokémon. Each Pokémon can gain a maximum of 510 EVs, with 255 in any single stat. Understanding these allows for highly optimized Pokémon builds.
