Nature

Natures are the Pokémon analogue of personalities. They were introduced by the Generation III games and remain a game mechanic in Generation IV. Each Pokémon in these games has one of 25 natures, as listed and described in the table below. A Pokémon's nature usually affects the growth rate of two of its stats, ultimately increasing one of its stats by 10% and decreasing another of its stats by 10%. Five of the possible natures, however, have no affect on the Pokémon's stat growth. (Note that despite these relationships to a Pokémon's development, natures do not affect experience or DVs.) Natures also determine the Pokémon's favorite flavor of food and which flavor it dislikes. The exception is again the five previously mentioned "neutral" natures, which cause a Pokémon to not like or dislike any flavor.

The following table lists each nature and its affect on a Pokémon; it may be rearranged by clicking the boxes next to each column's heading.
