Pokémon Natures Table

In the later generations, a system of Pokémon Natures was implemented into the games. Natures decide a small variation in the stats of Pokémon. For instance, a Pokémon with an Adamant nature will have slightly more attack and slightly less Special Attack than a Pokémon with a neutral nature, such as Hardy. Natures will also determine what kind of Pokéblock your Pokémon will like or dislike.
