A Pokémon's nature is one of the most important aspects of battling, and in Pokémon Legends: Arceus, players can change their Pokémon's nature easily with specific items. Pokémon natures were originally added to the series in Pokémon Ruby and Pokémon Sapphire, and they offer additional boosts to a Pokémon's stats.

Natures work independently from Effort Levels in Pokémon Legends: Arceus, though stats are affected by both values. The hidden stat values provided by natures in Pokémon Legends: Arceus can only be changed, but never increased nor decreased. Conversely, players can use Grit items to increase a Pokémon's Effort Levels. Although Effort Levels are random when a new Pokémon is captured, the values can always be increased to their max value. Natures, on the other hand, will provide their maximum value once a Pokémon reaches level 100 in Legends: Arceus.
