Zombie Wario

Zombie Wario is another of Wario's famous transformations in the Wario Land series of games. This creepy alter-ego is triggered by being touched by a ghost, spat at by a skeleton, or touched by a zombie enemy in Wario Land 2-4. When a zombie, Wario is imprevious to all enemy damage, can defeat almost all enemies on touch, and fall through thin floors, making it quite useful at times. Unfortunately, he moves at a very slow speed, and can barely jump (in his first appearance in Wario Land II, he couldn't jump at all). To return to his living form, Wario must walk into light or fall into a body of water. He also sometimes falls apart and then might come alive again.

Trivia

 * The artwork of Wario Land II shows Zombie Wario's skin still fresh, aparently; however, Zombie Wario's in-game sprites shows his skin with a black greenish-tone, possibly because descomposition, which contradicts the picture of the artwork.
 * Also, in Wario Land 4, although the artwork shows Zombie Wario's skin with a purple tone, however, the in-game sprites show his skin with a green tone.
