The Pokemon Company introduced, the natures of Pokémon in Generation 3 (Sapphire/Ruby). Nature increases the stats of your Pokemon, A Pokémon can have only one nature from the total of 25 different natures. Natures make the Pokémon unique from each other. It applies to pokemons when you receive or catch them. It can be one from different 25 natures, with the exception of 5, that will increase 1 base stat by 10 percent while decreasing another base stat by 10 percent. When you see the summary of your pokemon’s stats, the red would be the boosted stat and blue would be the decreased stat.
Trainers use this feature to upgrade the stats of their Pokemons. They increase the stats of their desired pokemon while reducing the other stat of that pokemon.
For example Alakazam, It is modes/timid in nature. Alakazam excels in speed & special attacks but you don’t need special attacks so you will skip that nature.
As we all know, Pokemons get the nature randomly. So, Trainers would need a large no. of same pokemon to gain the desired nature. The Pokemon has the synchronize ability the most, it will have 50% more chances of encountering with the pokemon with the same nature in the wild.
The below table is showing the list of all 25 different natures with the increase and decrease in the Base State:-
|Bashful||Sp. Atk||Sp. Atk|
|Careful||Sp. Def||Sp. Atk|
|Quirky||Sp. Def||Sp. Def|
|Rash||Sp. Atk||Sp. Def|
