Swarm (Ability): Difference between revisions

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, 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.

Description

Pokémon	Method
User	First Used In		Notes
	When Leavanny becomes tired or weak, its outline becomes surrounded by a light-green aura, powering up its Bug-type moves.
Ash's Leavanny	Strong Strategy Steals the Show!		Debut

• In A Connoisseur's Revenge!, Burgundy told Ash that his Leavanny, who at the time was a Sewaddle, had Swarm as his Ability. However, he was never seen using it as a Sewaddle.

In the manga

Pokémon Adventures

• In volume 23, Blue's Scizor was revealed to have Swarm as his Ability.
• Moon's Grubbin and Giovanni's Beedrill were revealed to have Swarm as their Ability in the PokéSPedia data-book.
• Winona's Beautifly, Alder's Escavalier, Emmet's Durant, a Roughneck's Mothim, and a Scolipede controlled by Colress were revealed to have Swarm as their Ability.

Trivia

• 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.
