In all games it appears in, a Pokémon's Nature is displayed on the Pokémon's summary screen. From Pokémon HeartGold and SoulSilver onward, the stats affected by a Pokémon's Nature are highlighted on their summary screens: the increased stat is notated in red text and the decreased stat is notated in blue.
A Pokémon's Nature usually affects the growth rate of two of its stats, ultimately increasing one of its non-HP stats (Attack, Defense, Special Attack, Special Defense, or Speed) by 10% and decreasing another by 10%. Natures also determine the Pokémon's favorite flavor and its disliked flavor. Each stat is associated with a flavor, and the flavor associated with the stat that the Nature increases will be the Pokémon's favorite. The opposite also holds true. For example, since the Lonely Nature increases a Pokémon's Attack stat (which is associated with the Spicy flavor) and decreases its Defense stat (which is associated with the Sour flavor), the Pokémon's favorite flavor will be Spicy and it will dislike Sour flavors.
A Pokémon's Nature is determined when it is generated by the game: when it is obtained as an Egg from the Pokémon Day Care (by the player in Generation III—except in Pokémon Emerald—and Generation V, or by the Day-Care Man in Emerald and Generation IV), when it is encountered in the wild, or when it is given to the player by a non-player character. In Generations III and IV, Nature is determined by the Pokémon's personality value. In later games, it is stored in an unrelated variable.
Every Nature represents one of the 25 unique possible combinations of stat increase and decrease; thus, there are five Natures that have no effect on the Pokémon's stat growth (Bashful, Docile, Hardy, Quirky and Serious). These five neutral Natures are technically Natures that increase and decrease the same stat.
List of Natures
The following table lists each one of the 25 Natures and their effects on a Pokémon.
|Nature||Japanese||Increased stat||Decreased stat||Favorite flavor||Disliked flavor|
|Rash||うっかりや||Sp. Attack||Sp. Defense||Dry||Bitter|
|Careful||しんちょう||Sp. Defense||Sp. Attack||Bitter||Dry|
As each Nature uniquely boosts one stat and hinders another, the 25 Natures may also be arranged into a table such as the one shown below.
From Pokémon Emerald onwards, a Ditto or a female Pokémon that holds an Everstone has a 50% chance of passing its Nature to its offspring when at the Pokémon Day Care. Starting in Pokémon HeartGold and SoulSilver, male Pokémon can also pass on their Nature by holding an Everstone. Starting in Pokémon Black 2 and White 2, the Everstone's effect was increased to 100% effectiveness.
In Generation IV, parents would only be able to properly pass down their Nature when holding an Everstone if both Pokémon came from games of the same language. If they did not, the Masuda method would activate and regenerate the personality value to attempt to make the Pokémon Shiny, thereby unsetting the Nature that had previously been set. In later generations, this was not a problem since Nature was separated from the personality value.
In the wild
Since Pokémon Emerald, if a Pokémon with the Ability Synchronize is leading the party, there is a 50% chance of encountering a wild Pokémon with the same Nature. Synchronize affects any encounter, including stationary legendaries, but does not affect Pokémon that were caught during a Stroll in the Pokéwalker or Pokémon received from a non-player character such as the Eevee that Bill gives or resurrected Fossil Pokémon.

All attacks are grouped into three categories: Attack, Defense (primarily status moves targetting the user), and Support (primarily status moves targetting the opponent).
All Natures have a set ratio of Attack, Defense, and Support moves that Pokémon with that Nature will prefer to use. These ratios may change when the Pokémon's HP falls below 50%. During battle, a Pokémon will select a category in which it wants to attack and then select a random attack from its moveset that fits that category; if no such attack exists, the Pokémon will "appear incapable of using its power" and skip its turn.
In side games
In Pokémon Colosseum and Pokémon XD: Gale of Darkness, a Pokémon's Nature affects the effectiveness of different purification methods. An action that greatly lowers the Heart Gauge of one Shadow Pokémon might do very little for another one based on their respective Natures.
A few natures appear in the Pokémon Mystery Dungeon series, whenever the player finishes their personality test. These natures determine which Pokémon the player will transform into.
In Diamond, Pearl, and Platinum, a man in the house closest to the Sunyshore City Heritage Site asks to see Pokémon with different Natures (Serious, Naive, and Quirky), and will give the player three Pokétch applications in return.
Starting in Pokémon HeartGold and SoulSilver, the stats increased or decreased by a Pokémon's Nature have (respectively) a red or blue highlight on a Pokémon's summary screen.
From Generation V onwards, the player can assign a Nature to their Trainer profile. In Generation V, this is part of their Trainer Card and affects what the player will say on others' games at the Unity Tower. In Generation VI, this is part of the player's profile in the Player Search System.
