Yes we found another Vilgax action figure! This is Ben 10 arch enemy. This is the Battle version which goes for about $90 online!
Vilgax is an intergalactic alien planet conqueror, a Chimera Sui Generis and is the most recurring villain in the franchise. He was introduced in And Then There Were 10, and has since appeared in all the seasons of the original series (however the only season 3 episode he appeared in was Ben 10,000), as well as season three of Alien Force and Ultimate Alien.
