Vilgax is an intergalactic alien warlord and conqueror that seeks to obtain the Omnitrix.
He looks exactly the same as he did before he was mortally injured in the main timeline.
This Vilgax first appeared in Gwen 10, the episode where Gwen got the Omnitrix instead of Ben. Unlike the main universe version, he managed to survive Xylene's counter-attack without injury by taking shelter behind his robots.
He attacked Ben and Gwen at a bowling alley and kidnapped Gwen. He put her in the same device he put Ben in (in Secrets), however, Gwen did not rapidly change between aliens. Vilgax was defeated by Ben using Max's laser gun. Max later threw Vilgax into the Chimerian Hammer as Upgrade, seemingly killing Vilgax.
