It can be triggered by coming in contact with a Kobatto, causing Wario to become a vampire. He is then able to defeat any enemy upon contact. By pressing on the ground, he will switch between forms; the bat form is slower, but is able to fly rather than jump. To turn into his normal self, he must touch a clove of garlic, go into a patch of light, or fall into a pool or droplet of water (similar to Zombie Wario). 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. A similar transformation known as Vampire Bat Wario appears in Wario Land 4.
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 a vampire. Defeating him in one battle will unlock Vampire Wario as a playable character.
