Vampire Wario

Vampire Wario is one of Wario's many transformations in the Wario Land series of games. It is also the most useful. It can be triggered by being touched by a Minicula, making Wario sprout a pair of suspicious, pointy canines and become Vampire Wario. He is then able to kill any enemy on touch. Plus, by pressing the B Button, Wario will go to Vampire Bat form, when he can fly in short spurts. To turn into his normal self, he must touch a clove of garlic, go into a patch of light, or fall into a pool of water. In Wario Land 4, Wario goes straight to bat form. Also, in Dr. Mario 64, if you have not lost at any point prior to this match in hard mode or greater, and choose to play as Dr. Mario, Wario will eat the Megavitamins and transform into him. Defeating him in one battle will make Vampire Wario a selectable character.

Trivia

 * Vampire Wario reappears in Mario Party 8, when Wario eats the Vampire Candy.
