the user converts its rage into energy to attack the more times the user has been hit by attacks, the greater the move's power

Every other Pokémon on the field.

Rage Fist inflicts damage. Its power increases by 50 each time the user was hit during a battle, by a move that causes direct damage (including times the user hit itself in confusion but excluding times the substitute was hit), up to a maximum of 350 (after 6 hits), with each strike from a multi-strike move counting as one hit. Recall|Switching out or fainting does not reset the hit counter
