## IVs, EVs & Natures

Three hidden numbers turn a species' base stats into the Pokémon in your party.

**IVs (Individual Values)** are a fixed genetic roll of **0–31** in each of the six stats, set the moment the Pokémon is created and never changing. Two Pokémon of the same species, level and training can still differ by up to 31 points per stat because of IVs; they also decide a Pokémon's Hidden Power.

**EVs (Effort Values)** are earned through battle and represent training. Capped at 255 per stat and 510 in total, every 4 EVs add 1 point at level 100. Unlike IVs they're under your control — see the EV Training guide.

**Natures** are one of 25 personalities fixed at creation. Most raise one stat by **10%** and lower another by 10% (for example Adamant boosts Attack and cuts Special Attack); five natures are neutral. Nature is tied to the Pokémon's hidden personality value, so it's locked in alongside its gender and shininess. Stats are computed from base + IVs + EVs + level, then the nature multiplier is applied last.
