Bull Wario

From the Super Mario Wiki

Bull Wario is a form Wario takes after eating a Bull Pot in the game Super Mario Land 3: Wario Land. In this form, Wario can destroy his enemies and blocks much easier. Wario can also create a shock wave by crashing into the ground with his weight, and stick to the ceiling. Wario can get this power in Virtual Boy Wario Land via a bull helmet.
