Eon is a villain who first appeared in Race Against Time. He was an inter-dimensional time-travelling alien who wanted to save his race and destroy Earth. However, almost all of his backstory was retconned when he appeared in Ben 10,000 Returns. He was changed to an alternate version of Ben 10,000 who wanted to capture and enslave all other Ben Tennyson and rule the multiverse.
