Bull Wario
Bull Wario is a form Wario takes after eating a Bull Pot or a Garlic Pot in any other forms except when he is small in the game Wario Land: Super Mario Land 3. In this form, Wario can destroy blocks with just one body slam instead of two, and is able to do a ground pound that destroys any enemy or block directly hit and creates a shock wave that stuns any nearby enemy. He is also able to stick to the ceiling with his horns.
Wario can get this power in Virtual Boy Wario Land via a Viking Helmet, or by getting another Garlic Bottle, once already in his normal form. The power works very differently compared to the Wario Land: Super Mario Land 3 version as it simply changes Wario's Body Slam to resemble a ground pound. In Virtual Boy Wario Land, this is one of the heaviest forms, making it hard to jump out of quicksand.
Artwork of Bull Wario can be seen on Wario's Galleon in Mario Kart 7.
