He also wore a brown belt and carried a sword.
Vilgax's true form was a green octopus with a huge, bulbous head and large mouth with many teeth. He had spikes running down his head.

Vilgax has a very evil mind. He loves to dictate others and wishes the galaxy belonged to him. He is also willing to do whatever it takes to make his wishes become reality. Although his main priority was the Omnitrix, he now also wants to kill Bеn Tennyson for defeating him and ruining his plans so many times.
Vilgax is super strong, stronger than any of Ben's aliens. He is also durable to the point where it is almost impossible to harm or defeat him. Vilgax is extremely intelligent and has great knowledge of the Omnitrix, making him especially dangerous to Ben. He also commands an army of drones.
Vilgax first appears in And Then There Were 10, where he is involved in a spac battle with Xylene. He hopes to retrieve the Omnitrix from her ship, but it is jettisoned to Earth instead. The battle injures Vilgax, leaving him disfigured and bound to a healing tank. He sends drones to Earth to retrieve the Omnitrix, but they fail.
In Hunted, Vilgax hires three bounty hunters to go to earth and retreive the Omnitrix. He soon learns that Tetrax one of the hunters is a traitor as he helps Ben get away from the other hunters. He then realized that Ben is as intelligent as he is strong.
He appeared in The Alliance where he first summons two of his drones to attack Ben and get the Omnitrix. Four Аrms however is able to defeat them while fighting against Rojo. Vilgax then soon realized that one of his drones have merged itself with Rojo giving her control of the power. Vilgax then contacts the drone within her brain to get her to obey him. He then commands Rojo to go after Ben and the Omnitrix. Later Upgrade merges with Rojo and the drone where he sees Vilgax for the first time inside Rojo's head. Vilgax sees Ben and warns him that he is going after him. Upgrade then releases the drone from Rojo capturing them both.
In Secrets Vilgax finally decides to confront Ben face to face. He has a long battle with him until he realizes Ben is just a child. He then captures Ben bringing him upon his ship to remove the Omnitrix from Ben's wrist. Max Tennyson then drives into Vilgax's ship using the Rust Bucket knocking Vilgax down. Vilgax quickly remembers Maх and realizes that he is related to Ben. Max and Ben are then able to defeat Vilgax while putting the Chimerian Hammer in self destruct. In the end the ship is seen blowing up with Vilgax inside it.
In Back With A Vengeance, Vilgax teams up with Kevin to take the Omnitrix. Ben has recently unlocked master control. With many attempts, they are eventually trapped in the Null Void. Thinking he had the Omnitrix, Vilgax is fooled and is trapped in thе Null Void.
