Pokémon/Competitive battling/Natures

First, please note that Natures only appear in the Third and Fourth Generations. Natures are like Traits; they are automatic. However, Natures raise a certain stat while lowering another stat, or they could have no stat changes at all. The change will be 10% in either direction. Also, all Pokémon can randomly have any Nature from the list below, while each Pokémon can only have one or two Traits assigned to them. Natures are like IVs in a way. If you want a Pokémon with a specific Nature, it is very hard to do so because it is random, but still possible since Natures are not hidden and there are fewer Natures than there are IVs. Natures are important because they give a boost in your Pokémon's strengths. If you are, you would love a 10% boost in Attack while would not mind a 10% decrease in Special Attack. Below is a list of Natures in the order of what it increases, what stat they increase, and what stat they decrease. Note that Natures do not alter a Pokémon's HP stat.
