Eon (villain)
From Ben10versepedia
Eon is the alien set to appear in Ben 10: Race Against Time, played by Christien Anholt. Not much is known about him except that he is the main villain, and well-known among The Plumbers. He possess some sort of energy-emitting powers, able to project beams of destructive force from his hands, and can disrupt the Omnitrix through some unknown means. He wants Ben to rule the galaxy at his side and claims he can turn Ben from a "helpless child" into a "god".
Christien Anholt, in a behind-the-scenes video hosted on Cartoon Network's video service, says that parts of the character are inspired by Darth Vader, whom Anholt is a fan of.
