Zombies

Zombies are unintelligent monsters that XANA creates in the image of real people. In Ghost Channel, the computer-programed people inside the Earth-disguised Guardian could turn into Zombies at XANA's will, and in Attack of the Zombies, Kiwi started an pandemic that turned actual people into zombies by biting them. The first victim was Tamiya and the last one was Jeremie, who still managed to start a return to the past. The only people who escaped zombification were Aelita, Ulrich, Yumi, Sissi, and Milly. Zombies are identifiable with their bluish skin, emaciated faces, sharp teeth, sharp nails, and pupil-less eyes.
