Vampire Wario

Vampire Wario is one of Wario's many reactions in the Wario Land series of games, appearing in Wario Land 3. In Wario Land 4, it is replaced by the similar Bat Wario.

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 which can be used to get foes blocking Wario's path such as Prince Froggy. By pressing on the ground, he will switch between forms; the bat form, also called Bat-Wario, is slower and cannot walk, but is able to fly rather than jump. To turn back to 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), meaning that if Vampire Wario is required in another part of the level, the aforementioned objects are basically obstacles. Vampire Wario cannot cross waterfalls, unlike normal Wario.

In Dr. Mario 64, if the player is playing as Dr. Mario and has not lost or rematch at any point in normal mode or greater, Wario will eat the Megavitamins and transform into a vampire and a match will ensue. Defeating him in one battle will unlock Vampire Wario as a playable character. In multiplayer modes, Vampire Wario has the highest-level AI along with Rudy and Metal Mario. Vampire Wario's losing animation has him transform into a bat, while his winning animation has him cackling.

Trivia

 * Wario's vampire form is somewhat ironic because he eats garlic, a plant that is said to repel vampires. However, in the actual novel , garlic flowers are used to repel Dracula, not garlic heads, potentially lessening the irony.
 * The music heard while Wario sports his vampire form shares similar percussion and overall tone with the music that plays when inside Snide's HQ from Donkey Kong 64, although it is 8-bit because of the Game Boy Color hardware limitations.
 * While the form itself does not directly appear, Wario turns into a vampire when using a Vampire Candy in Mario Party 8, and upon successfully completing the microgame Wet Your Whistle on the highest difficulty in WarioWare Gold.
 * Vampire Wario is the only reaction to have a unique Action Help demonstration, but not the only one with a unique demo (Wario holding a zipline handle and Wario holding an Owl also have different Action Help demos).
