Vilgax (BTR)

Vilgax is a major villain in Ben 10: Revamped, and so far seems to be Ben's arch-enemy.

Biography
Prior to the series, Vilgax had heard of Azmuth's Omnitrix project, and had tried to steal it many times.

Answers
In the beginning of the series, Vilgax confronts Azmuth in his space station, but ultimately causes the room to be launched out as an escape pod. Ultimately, Azmuth launches the pod containing the Omnitrix away from Vilgax to protect it, but he jumps after it, leaving the escape pod to crash. All three hit the ground in different places.

Later, he finds the Plumber, who had earlier taken the Omnitrix from Ben, and tries to steal the Omnitrix. However, Ben had locked the Omnitrix so that the Plumber turned into a clone of him (kinda like canon Albedo), and then he shows up to explain. Ultimately, Ben pulls the switcheroo on him, giving him a fake Omnitrix that blows up instead of transforming the wearer.

Ben, now with the Omnitrix again, turns into Copycat, and his duplicates form a giant Copycat that picks up Vilgax and hurls him into space. His fate is unknown.

Trivia

 * Evidently, Vilgax is very durable, surviving the explosion of the fake Omnitrix without being harmed.
