Vampire Wario

Vampire Wario is one of Wario's many transformations in the Wario Land series of games. It is also probably 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 defeat 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. The patches of light become obstacles for Vampire Wario, as he must avoid them when he does not wish to resume his adventure in his normal state. In Wario Land 4, Wario goes straight to bat form. In Dr. Mario 64, if the player is playing as Dr. Mario, and has not lost at any point prior to Wario's second match in hard mode or greater, Wario will eat the Megavitamins and transform into him. Defeating him in one battle will unlock Vampire Wario as selectable character.

Trivia

 * In WarioWare, Inc.: Mega Party Game$, Vampire Wario's bat form cameos in a beginning video, where he chases a pigeon across the screen, and gets chased by a few pigeons back across the screen.
 * Wario's vampire form is somewhat ironic because he eats garlic, a food that repels vampires.
