Eon is Ben from another timeline. He used the Race Against Time Ben to activate the Hand of Arrmegedon (Or however that is spelled), but failed, so he went to other dimensions to absorb every Ben 10 he can find. He was destroyed in the Ben 10: Ultimate Alien episode Ben 10,000 Returns, and the absorbed Bens went to their normal timelines
