Aggregax is a villain in Ben 10: Omniverse Traveler.


Aggregax appears very similar to a hybrid of Aggregor and Vilgax.


He acts similarly to Aggregor, but also seems to have gone a bit power-mad.


Aggregax first appeared in The Omniwar, when Vilgax got the Omnitrix and attempted to absorb Aggregor. However, Aggregor planned on this, and reveals that he sabotaged Vilgax's assimilation device. Thus Aggregor absorbed Vilgax and the Omnitrix, taking this form. In Vengeance of Aggregax: Part 1, he defeated Kevin, Rook, and Gwen easily, forcing the heroes to flee to Galvan Prime. In Vengeance of Aggregax: Part 2, he chases the heroes to Galvan Prime, where Rook, Kevin, Gwen, and the Galvan military try to hold him back while Ben goes to Azmuth for help. Gwen, Kevin, and Rook are heavily injured, and several Galvan die, but they successfully hold off Aggregax long enough for Azmuth to give Ben the Ultimatrix. After a battle, he is defeated by Ultimate Four Arms, and gets launched outside. However, once outside, he activates Way Big and Atomix powers, turning to the size of a skyscraper. He is then defeated and stripped of his power by fighting Ultimate Chromastone, turning him back to Aggregor.

Powers and Abilities

He has all the abilities of all of Ben's aliens, plus those of Vilgax and Aggregor.


He is vulnerable to Ultimate Chromastone's energy draining abilities. He is also unaware of a lot of the powers he has acquired, like the celestialsapien and Crystalsapien DNA.
