An Ability is a passive trait that can affect battle, exploration, or both. Examples include abilities that reduce damage, change weather, prevent sleep, boost a move type, or activate when the Pokémon enters battle. A species may have more than one regular Ability, so two Pokémon of the same species can work differently. Some species also have a Hidden Ability, which is obtained through game-specific methods rather than ordinary wild encounters. Read the exact Ability description in the game because its behavior can differ by generation. When building a team, choose an Ability that supports the Pokémon’s role rather than selecting only by name.
