Zombie Wario

Zombie Wario is one of Wario's transformations in Wario Land II, Wario Land 3 and Wario Land 4. This undead alter-ego is triggered by being touched by a Zombie (Wario Land II and Wario Land 3) or spat at by a Skeleton Bird (Wario Land 4). When a zombie, Wario is impervious 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, can barely jump (in his first appearance in Wario Land II, he couldn't jump at all), and often his ability to fall through thin platforms is used to hinder him. To return to his normal 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, apparently; however, Zombie Wario's in-game sprites shows his skin with a black greenish-tone, possibly because of decomposition, which contradicts the picture of the artwork.
 * In Wario Land 4, although the artwork shows Zombie Wario's skin with a purple tone, the in-game sprites show his skin with a green tone.
