|Achieved By||Touching a Bull Pot or touching Garlic when in Normal form.|

|Stick to ceiling, more powerful Barges and the ability to Ground Pound|
In this form, Wario's hat is replaced by a grey helmet with yellow bull horns.
In Wario Land: Super Mario Land 3, Bull Wario was much stronger and was able to perform a Ground Pound and stick into the ceiling thanks to his horns.
In Virtual Boy Wario Land, this form was the heaviest of the game and allowed Wario to perform a ground pound.
This appeared as Wario's exclusive power-up in the game. Presumably has the powers it did in Wario Land.
