NATURES
All 25 natures and how they affect stats
How to read natures
Each of the 25 natures raises one stat by 10% and lowers another by 10%, except five neutral ones that change nothing: Hardy, Docile, Serious, Bashful and Quirky. HP is never affected by nature, so every combination comes from the other five stats. The list shows each nature with its English and Spanish names, the stat it raises and the one it lowers.
The cross table turns it around: each row is the stat that goes up and each column the one that goes down. For a fast physical attacker, find where the Speed row meets the Special Attack column, and there is Jolly. The neutral natures run along the diagonal. Choosing a nature means choosing which stat to give up, and the usual pick is the attacking stat your Pokémon will not use.
