Monster Break (モンスターブレイク,Monsuta Bureiku) is a Rush Attack used by Zarbon in his monster form.
As he says "don't be shocked", Zarbon knees the opponent in their stomach. Then, he slaps the opponent in the face and kicks them up into the air. Finally, while saying "behold my power!", Zarbon grabs the opponent by their leg and swings them onto the ground, inflicting a high amount of damage.
Zarbon uses this attack during his battle against Vegeta after transforming into his monster form, battering the Saiyan prince.
