Powers up Bug-type moves when the Pokémon is in trouble.
Swarm (Japanese: むしのしらせ Bug Notification) is an Ability introduced in Generation III. All Pokémon that have this Ability are Bug types.
Generations III to IV
When a Pokémon with Swarm uses a
Bug-type move, the move's power will be increased by 50% if the user has less than or equal to ⅓ of its maximum HP remaining.
Generations V onwards
Instead of boosting Bug-type moves' power, Swarm now technically boosts the Pokémon's
Attack or Special Attack by 50% during damage calculation if a Bug-type move is being used, resulting in effectively the same effect.
Outside of battle
Pokémon Emerald, this Ability also increases the frequency cries of wild Pokémon that are heard in the overworld.
Pokémon Emerald onwards, if a Pokémon with Swarm is in the first place in the party (even if fainted), the wild Pokémon encounter rate of all Pokémon is doubled. It shares this trait with Illuminate and Arena Trap.
Pokémon with Swarm In other games
If a Pokémon with Swarm is below 25% of its HP, the power of
Bug-type moves increases by 2-times R B or 1.5-times T D S GtI .
Pokémon Conquest, Swarm will increase user's Attack if the Pokémon using it is below ⅓ of its HP.
