Flaming Wario

Probably Wario's most famous transformation in the Wario Land series, Flaming Wario. In Wario Land 2-4, when hit by a Torcher (a torch-holding fox enemy), Wario will comically start racing around with his pants on fire. In this state, he cannot be controlled, except for jumping. Soon, the flames will spread across his entire body, making him essentially a living Fireball. He can now be fully controlled (although slowed down a bit) and can destroy blocks with a fire symbol on them. This can be cured, obviously, by falling into water or just waiting until he burns out. Also, it is known as Hot Wario in Wario Land 2. Ball o' String Wario combines this ability with Snowman Wario.
