Swarm is an ability in the Pokémon series introduced in the third generation that is currently used by several Bug-type Pokémon.


This ability allows the Pokémon that is using it to raise its Bug-type moves by 50% if the Pokémon using it has less than one-third of its maximum HP.

Outside of battle, if the Pokémon leading the party has Swarm, the chance of encountering wild Pokémon increases from Pokémon Emerald and onwards.

If a Pokémon with Swarm is below 25% of its HP, its Bug-type move hits can have double damage.
