Green Devil

Origin
It is unclear if the Green Devil is a demon or a scientist, as some of his abilities seemed magical in nature, and some were clearly technological. He was a giant creature, standing about 15 feet tall, with green skin and horns. He ruled Death Island from a palacial throne room. He possessed a palanthir which allowed him to see distant events, and which nullified all magic but his own, within the immediate vicinity. He used a special gas to turn people into zombies, and his zombies served him faithfully as soldiers and workers. He was able to teleport himself and his zombies in a flash of fire. He also possessed a huricane machine which could turn the weather around Death Island extremely violent. His palace included an astronomy room, where he believed he was close to discovering all the secrets of the universe. The Green Devil was confronted by Diamond Jack.
