Despite his enhanced durability, there is a limit to how much Vilgax can take. His size makes him unable to move in tight spaces.


Vilgax was born in 1618 on Vilgaxia. He joined Vilgaxia's military in his youth before taking a path of power. He decided to seek out the Omnitrix which he believed would grant him ultimate power. He followed it to earth, where Xylene was taking it to be safe from him, but he destroyed her ship and the Omnitrix went to earth in an escape pod. He discovered Owen Johnson found the Omnitrix and sent drones to retrieve it, but Owen defeated them. Vilgax sent various drones and villains to retrieve it, but after the failure of his second-in-command Psyphon, he decided to face Owen himself. He defeated Owen and took him to his ship, the Chimerian Hammer, where Owen defeated him.
