Flash Fire in Pokémon Black & White

It powers up Fire-type moves if it’s hit by one.

Protects against Fire moves. Once one has been blocked, the Pokémon's own Fire moves inflict 1.5× damage until it leaves battle.

This Pokémon is immune to Fire-type moves. A Fire-type move activates a 1.5× boost to its own Fire-type attacks; further hits do not stack the boost. In Black and White, Flash Fire also works while frozen and does not thaw the Pokémon. Will-O-Wisp can activate it. Switching out clears the boost.
