Vilgax is an intergalactic alien warlord and conqueror, a Chimera Sui Generis who serves as Ben's archenemy, and the most recurring villain in the ongoing franchise, having appeared multiple times in all the series. Ben considers him as one of the most dangerous villains he has faced.

Vilgax was the primary antagonist of Ben 10, Alien Force, and Ultimate Alien.


Vilgax is a humanoid creature with a face resembling that of an octopus. He has tentacles dangling in the front of his face, like a beard. His skin is pale-green with yellowish spots on his face and tentacles. He doesn't have a nose and a visible ear. He has red eyes.

In the original series he wore a black and red-brownish armored suit and gloves. His armor is spiked at the shoulder and arm pads. He has green sacs on the sides of his head. His mouth was attached to the sacs by a respirator.

As of Secrets, he had become much more burly than before. He now had a mask covering his mouth, attached to the armor, and new shoulder and leg pads. He also had metallic gloves with small fingers as well as reddish brown cylinders-like objects piercing his arms, giving him much stronger and more muscular limbs. His tentacles are now much longer. He has 6 tentacles in front and 2 behind.

In Alien Force/Ultimate Alien, he no longer has red-brownish armor, mask, and green cheek sacs. He wears a red and blue armor. He has a belt which is attached to the Raygun pocket. He wears dark blue stockings with metallic squares. He has a Ruby Ray of Rouleau on his right hand, a Shield of Seagle on his left arm. He now has just five tentacles, all on the front of his face, and his eyes were larger. He also has a metallic part replacing the green sac on his head.

In Primus and The Final Battle: Part 2, Vilgax wears the Omnitrix on his right hand.

In his true form, he 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.

In Omniverse, he looks almost identical to his original design. He no longer has the Ruby Ray of Rouleau or Shield of Seagle. He regained his original green cheek sacs. He has dirty teeth. Two of his face tentacles now end with a spiky-looking shape, resembling actual squid tentacles. His armor is similar to his original series, with the exception being the cylinders on his arm and armour now being gold in colour. He wears black clothes underneath his armour and black stockings. He now has fingerless gloves. He wears a headpiece similar to his shoulder pads.

Occasional Appearances

In The Secret of Chromastone, Vilgax was seen wearing his Alien Force armor but blue rather than red.


A cruel, galactic warlord known as "the most dangerous being in the universe". Vilgax's singular goal is to acquire the Omnitrix, and use its technology to build an army capable of transforming into aliens at his command, then use that power to conquer the entire universe.[2] Though he originally chased Ben Tennyson merely to achieve this goal and had few concerns about his fate once he had the Omnitrix, his constant defeats brought on by him, as well as his imprisonment in the Null Void by his hands, his hatred for Ben grew to the point that he seems to want to kill him as much as, if not more than, getting the Omnitrix.

Vilgax is one of the most feared beings in the universe, having conquered ten planets, destroyed five others, and created a black hole. He has such a fearful reputation, that almost no sentient being is willing to work for him (with the exception of Psyphon), forcing him to use Drones, which are obedient machines made to serve him as his ship crew and as his soldiers. However, he can find mercenaries willing to do his work for the right price.


Vilgax is ruthless, cruel, and power-hungry. In nearly all his encounters, Vilgax operates with the single-minded objective of acquiring the Omnitrix, which is the key to ultimate power. He is known to hold a grudge; most notably against Max and his family for the great number of losses he has suffered at their hands. He is also known to be very manipulative, notably so of the Galactic Code of Conduct, in order to achieve his goals. After escaping the Null Void, Vilgax seemed to have gone partially insane, as he was enraged more easily and exhibited facial ticks.[3] He appeared to have recovered by Alien Force.

While stranded on Earth following his defeat at the end of Alien Force, Vilgax skillfully manipulates a group of humans known as the Flame Keepers' Circle into serving him. Upon discovering that his squid-like form resembles the alien of knowledge worshiped by the cult, he adopts the role for his own and manipulates his new followers into helping him escape the planet.[4]

Despite his cruel and villainous tendencies, Vilgax does care about his own people (taking his role as Vilgaxia's ruler and champion very seriously), so much so that he is willing to put his own life on the line and use whatever other means necessary to ensure Vilgaxia's and its people's safety; even if it means begging his enemies for help.[5]

Vilgax is highly afraid of Ma Vreedle,[6] and there is a rumor that Ma Vreedle once made Vilgax cry.[7][8]

By the time of Omniverse, it would seem Vilgax's cruelty and ruthlessness have reached new heights, best exemplified when detonated his Chronosapien Time Bomb to wipe out all but No Watch Ben's timeline.[9]

Before his augmentation, Vilgax did not display any special powers or abilities, except for tremendous agility and hand-to-hand combat skills. He already had enhanced strength and endurance, once surviving a nuclear explosion at point-blank range, though it was made clear he was seriously injured and widely believed to be dead at that time.[10]

Due to his cybernetic enhancements, Vilgax became much taller and was granted immense strength and near invulnerability, allowing him to easily leap above skyscrapers and survive in space. His arms were equipped with boost steroids, allowing him to increase his own strength and rage even further at will. Though it causes him great pain,[pop-up 1][11] the boosters give him enough strength to smash apart mountains with his bare hands.

Vilgax possesses enhanced strength, being able to easily defeat Ultimos, Manny,[12] and even Humungousaur[13] with a single punch (the impact of which created a large crater in the ground). He could also break through Stinkfly's goo.[2]

Vilgax possesses enhanced durability, easily withstanding Chromastone's lasers,[13] Swampfire's fire blasts,[14] and even Heatblast's most powerful heatwave with no visible damage. He was also able to make Diamondhead shatter his own fists,[2] safely pass through Earth's atmosphere,[5] and recover within seconds from the Omnitrix's explosion.[14]

Vilgax possesses enhanced reflexes, as he once stopped a full-speed XLR8.[2]

In the original series, Vilgax conditioned himself to survive against the harsh conditions of space without protective gear for brief moments.[pop-up 2][3] By Alien Force, he became seemingly able to travel through space without any visible equipment.[5]

Vilgax can fly at high speeds.[5]

Vilgax can jump several times his own height.

Vilgax can project red laser beams from his eyes, capable of making drastic arcs to assist the pursuit of their target. These lasers are incredibly fast, as they were able to catch up with Helen.[12] They can also burn Ectonurites.[5]

Vilgax can hear sounds that are too faint for normal hearing to detect.[15]

Vilgax has breath so powerful that it can cause cyclone-like winds.[12]

Vilgax can turn into a giant octopus-like monster, which he referred to as his true form, in the ocean.[14] He had this ability since the very beginning, and can transform at will.

Similar to how an octopus regrows limbs, Vilgax can speak to and through his DNA,[DR 1] as shown when he talked to Upgrade when he was merged with Rojo.[16]

For most of the original series, Ben was unable to defeat him alone, always winning thanks to external help. Once Ben gained access to Way Big, he was able to defeat Vilgax with ease. After he became the "Conqueror of 10 Worlds", battling and defeating the champions of each, he drained their powers and abilities and added them to his own arsenal. One of those warriors was Ultimos.[12]

After becoming the Herald of Dagon, Vilgax was given increased power and the color scheme appearance of a Lucubra. He could project and manipulate energy blasts from his hands and eyes, and could also move between Dagon's dimension and back at his, like the Esoterica.

Vilgax used to have Dagon's powers after he absorbed his essence into himself, which amplified his absorbed and Lucubra powers greatly. He lost both his Dagon and Lucubra powers when Ben used Ascalon to take the power into itself and revert Vilgax back to normal.[17]

When he lost the powers he stole from the heroes he defeated, all Vilgax has left is his monstrous physical strength and resistance. In addition, he can also project red energy blasts from his hands.


Vilgax could use the Ruby Ray of Rouleau as a laser projector, and was able to considerably weaken Ultimos with one shot.[12] According to Vilgax, Ultimos' ability to survive the shot was unusual, suggesting that most other beings would be immediately killed.

Vilgax could use the Shield of Seagle to generate a powerful personal force field. The force field can become a knight-like shield on his arm or a dome/sphere to protect his whole body, and is able to defend him from attacks such as Ultimos' punches,[12] Jetray's neuroshock blasts,[13] or the guns of a spaceship.[5] It can even let Vilgax cut clean through that same spaceship.

Vilgax could use his gauntlet as a taser, allowing him to grab and shock Big Chill while intangible. It also gave him the ability to coat his hands in light energy and use them as boxing gloves.[13]

Vilgax's Sword can project energy beams or coat itself in flames, or crystals able to refract Chromastone's ultraviolet beams.[13] Even without the flames or crystal, the sword is incredibly sharp, able to easily cut though stone, Chromastone, and even an entire space ship with a single stroke.

Vilgax kept a raygun in a holster on his right hip. Vilgax lost all of his equipment excluding his sword when he was arrested after The Ultimate Enemy: Part 2.

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 literally punch anything off Galvan Prime and Galvan B with no difficulty, including Atomix, one of Ben's strongest aliens.[18]


Vilgax is vulnerable to the cold virus.[15]

If Vilgax is in his true form and becomes too weak, he cannot change back into his humanoid form.[4] He also needs to be in water in this form.[MW 1]

Despite his durability, Vilgax is limited to how much damage he can take.

His size makes it difficult to fit into small entrances.

Vilgax is terrified of Ma Vreedle and will leave the scene if she is present.[6] He can be also terrified of Toepick's face.[DJW 1]

  • In Omniverse, Derrick J. Wyatt had intended for Vilgax to look like his original self, but Matt Youngberg thought Vilgax's Alien Force/Ultimate Alien appearance had more personality.[DJW 2]
    • Derrick designed Vilgax with the respirator he had back in the original series, but executives discarded it because they wanted the character to emote more clearly. Derrick hoped to eventually use the respirator on the design, but it never came to pass.[DJW 3][DJW 4]
  • Dwayne McDuffie thought of Vilgax as Ben's most relentless enemy.[DM 1]
  • Vilgax is the most powerful Chimera Sui Generis.[DM 2]
