Swarm (Japanese: むしのしらせ Bug Notification) is an Ability introduced in Generation III.
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 onward
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
In Pokémon Emerald, if the first Pokémon in the player's party has this Ability, the frequency of cries of wild Pokémon that are heard in the overworld is increased. Despite the fact this mechanic also exists in Pokémon Sun, Moon, Ultra Sun, and Ultra Moon, Swarm has no overworld effect there.
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-timesRBTDS or 1.5-timesGtISMD.
In Pokémon Conquest, Swarm will increase user's Attack if the Pokémon using it is below ⅓ of its HP.

In the manga
- The Japanese name for Swarm, むしのしらせ Mushi no Shirase (Bug Notification), is a Japansese expression that translates to "foreboding; premonition; gut feeling". This is reflected by the way the Ability works, as the Pokémon is preparing itself for a tough fight by making itself stronger.
