Swarm (Japanese: むしのしらせ Bug Notification) is an Ability introduced in Generation III.

Effect

In battle

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, this Ability also increases the frequency of cries of wild Pokémon that are heard in the overworld.

Trivia

  • The Japanese name for this ability, 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.
