Natures are a Pokémon individuality that constitutively impacts the outgrowth of a Pokémon's stats.
A Pokémon's Nature and its affected stats are highlighted on the hover-over Pokémon card; see the pictorial illustration to the right.
Natures affect the statistical outgrowth of two non-HP stats: one additive stat that it increases and one subtractive stat that it decreases, thereby affecting the Pokémon's stats bilaterally. The differential produced by Natures is 10% of the raw stats.
There are also five neutral Natures that are completely impactless on the Pokémon's stats and are considered fodder for Pokémon that are to be unaffected by Natures; read the tabular index below.
Natures are randomly generated when a Pokémon is captured and they cannot be changed. Legendary Pokémon are the sole exception to this rule.
Nature Reroll Ticket
Legendary Pokémon can change their nature by using a Nature Reroll Ticket. By using one, you will be able to select your desired nature for your Pokémon.
Nature Reroll Tickets are purchasable from the PvE Shop and the PvP Shop; they will cost 150 and 75 coins, respectively. The Suspicious Bot can also reward a Nature Reroll Ticket on the 40th consecutive victory.
- Have it in the first slot, both fainted and healthy will work
- Healthy in the second slot, while the Pokémon in the first slot is fainted (this method is used for repel tricking)

Determining your Pokémon's optimal Nature
Akin enough to determining the optimal EV apportionment for Pokémon and what acceptable permutations of IVs that there may be, the crux of the conundrum is knowing what stats are the most vital to your Pokémon.
A tapestry of factors must be considered to determine the optimal Nature of a Pokémon, which include: the Pokémon's Base Stats (higher base stats greaten the differential of the Natures itself), the most viable moveset of the Pokémon for the offensive statistics, extrapolated PvP match-ups, the Pokémon's archetypal role in battle, and so forth. For example, Steelix's putatively optimal Nature is Impish, which increases a Pokémon's Defense and decreases its Special Attack; this is attributable to the Pokémon's tremendous Defense Base Stats and the predominance of Physical-powered moves in its move pools.
Due to various complicators, such as the unpredictability of PvP match-ups and considering whether or not the Nature is compensating for IV deficiencies in the stats, for examples, there is not any categorical guideline for determining what is the optimal Nature for a Pokémon; there are only a set of factors that you must consider to determine it at your own discretion, as noted above.
