There are 25 different Natures in the game, each with its own positive and negative effects on specific stats. For instance, a Pokémon with a Hardy Nature has no stat adjustments, while one with a Jolly Nature has a boost to its Speed and a decrease to its Special Attack.
Understanding and managing Natures is crucial in building an effective Pokémon team, as they can impact the Pokémon's overall strengths and weaknesses. Players can encounter and recruit Pokémon with specific Natures while exploring dungeons or by using the Wonder Mail feature to connect with other players.
