In his true form, Vilgax more closely resembles an octopus, having the shape of one with many tentacles. He has three spikes on his head. He has gills on his cheeks. Vilgax was originally stated to be 15 feet tall. [AC 1] However, this was retconned in Alien Force, in which he is as tall as Humungousaur (12 feet). [23]

Welcome

You hold the key to a power struggle so ancient, so vast, it is beyond your feeble comprehension. Picture an entire army, each in command of an Omnitrix and all at my command. I will be invincible. I will rule the Universe! And the only thing standing between me and my destiny... is you! Albert Torres to Draft Live Action Ben 10 - ComingSoon.net". 31 January 2012.

Gwen defeated some of Vilgax's Bioids by setting the simulator on the Resolute to recreate a solar storm - the highest level there is. [pop-up 15] Vilgax is the second and penultimate villain in The Alien Device, that capture Max and Gwen to an military base in the desert. But then Ben go to foil his plan and when he transform into Heatblast, he fails to beat him but sends to the Null Void along with Kevin.

Vilgax is fireproof, being able to withstand Swampfire's fire blasts, [16] safely pass through Earth's atmosphere, [7] and even survive Heatblast's most powerful heatwave with no visible damage. [2] Even Ultimate Swampfire's Azur fire didn't seem to do any visible damage to Vilgax. The Battle of Xenon will be recorded in the history of the Plumbers as an important turning point for Ben and Gwen. [pop-up 20] After fusing with Malware's remains, Vilgax gained access to Malware's ability to absorb technology, and access to all the technology Malware absorbed. His already mighty physical strength was increased to where he could punch anything off Galvan Prime and Galvan B with no difficulty, including Atomix, one of Ben's strongest aliens.

As such, he would get revenge on anyone who defeated him before. This shows that Vilgax can hold a grudge, most notably against Max and his family for the great number of losses he has suffered at their hands. Between this and his imprisonment in the Null Void, he has developed such a pathological hatred towards Ben that he wants to kill him as much as getting the Omnitrix. Of course, Vilgax's quest for the Omnitrix slowly became his secondary goal as his desire for Ben's defeat and/or death became even greater.
