Beat Up is a damaging Dark-type move that hits once for every Pokémon in the user's Trainer's party that is not fainted, paralyzed, poisoned, asleep, burned, or frozen to attack the target. Depending on how many able Pokémon are in the Trainer's party, Beat Up may hit 1-6 times. The base power of each hit depends on the corresponding Pokémon's base Attack stat, calculated by the formula, Base Attack/10 + 5. Beat Up ignores any changes to the Pokémon's Attack stat except for held items.
