Vilgax (info)

**Vilgax** is an intergalactic alien warlord and conqueror, a Chimera Sui Generis-Great Old One Hybrid who serves as Ben 10's friend and former archenemy and the most recurring former villain and hero in the ongoing franchise. He was introduced in *And Then There Were 10* and has since appeared in all the seasons of the original series (however, the only season 3 episode he appeared in was *Ben 10,000*), as well as season 3 of **Alien Force** and **Ultimate Alien**.

Vilgax was the main antagonist of the first three series (**Ben 10**, **Alien Force**, and **Ultimate Alien**).

He is also the son of Great Old One Cthulhu and Myaxx.

## Background

A vicious, galactic warlord known as "the most dangerous being in the universe". Vilgax's singular goal is to acquire the Omnitrix device and use its technology to build an army with each troop capable of transforming into aliens. Being able to command such an unstoppable force would allow him to rule the entire universe. Though he originally chased Ben Tennyson merely because of this and had few concerns about his fate once he had the Omnitrix. The several failures the boy caused 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 is so feared, that almost no organic life form 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 his soldiers. However, he can find mercenaries willing to do his work for the right price.

## Personality

Vilgax is ruthless, cruel, and power-hungry. His primary objective seems to be obtaining the Omnitrix, so that he can use it to take over the universe. He is known to hold a grudge; most notably against Max and his family. 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. 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.

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.

## History

### Ben 10

Vilgax first appeared in *And Then There Were 10*, where he is seen shooting at Xylene's ship to recover the Omnitrix, forcing Xylene to throw it down to Earth and causing the main plot of the series. His limbs were both destroyed because of the battle thanks to one last-ditch attack that hit the main bridge of the Chimerian Hammer, causing him to be placed by his drones in a repair tank for healing.

As the series progressed, Vilgax soon discovered the Omnitrix had been taken by someone else (though ignoring exactly who it was) and made several indirect attempts to get the device back. This includes sending Drones from his ship, hiring bounty hunters (Tetrax Shard, Kraab, Sixsix and Rojo by fusing her with one of his drones). In the latter, he was able to shortly establish a telepathic link with Ben 10 when the boy was fused to Rojo as Upgrade, warning him he was going to come for him one day.

Eventually, his body was repaired and cybernetically enhanced in *Secrets*, making him far taller and stronger than before. He then went on Earth to get the Omnitrix by himself. Ben's aliens proved to be no match for him and Vilgax captured him. Though surprised to see the one who had caused him so many problems was just a human child, Vilgax revealed his plan for the Omnitrix to Ben 10 and attempted to extract the Omnitrix from him, seemingly by sectioning his arm with an alien tool. After several complications, including interruption from Gwen and Max and Ben 10 losing control of his transformations, the Chimerian Hammer exploded, seemingly with Vilgax still aboard.

At the end of the second season, Vilgax is still alive, having survived the destruction of his ship by teleporting out just before the explosion, but having been frozen as a result. He is found encased in ice by Kevin 11. Discovering Kevin 11's connection with the Omnitrix, Vilgax decides to team up with him in another attempt to retrieve the Omnitrix, however both are locked away in the Null Void dimension by the end of the episode.

A dream version of Vilgax appears in the episode *Perfect Day*, where he appears to confront Ben 10. The battle lasts for a short time and then Vilgax tries to send Ben to the Null Void. As Four Arms, Ben 10 throws him in instead, but this proves to be an error on the part of the Forever Knights, as Vilgax was about to send Ben 10 to the Null Void without first obtaining the Omnitrix. This is the reason why Ben 10 found out that the battle with "Vilgax" was just a set-up.

Vilgax reappears in ***Ben 10: Secret of the Omnitrix***, where he once again attempts to retrieve the Omnitrix, having somehow escaped the Null Void (the enhanced version of *Secret of the Omnitrix* revealed that he stumbled on a Null Void portal being opened and used it to escape). During a flashback, Tetrax reveals that Vilgax destroyed the Petrosapiens' home world and he (Tetrax) unwittingly gave Vilgax the final element needed to carry out his plan. Vilgax refers to his anger at having been trapped in the Null Void (including showing a short nervous twitch at its mention), which has deepened his grudge against Ben to the point where he refuses to acknowledge the danger threatening the universe if the Omnitrix self-destructs (but nevertheless gains enough respect for Ben 10 to the point of calling him by his first name instead of his last name). He confronts Ben 10 on Tetrax's ship and attacks him, only to be shot out into space through the airlock. He is finally defeated when Azmuth, the creator of the Omnitrix, gives Ben 10 access to a massive alien, Way Big, who hurls Vilgax into outer space.

### Alien Force

At some point, Vilgax is fending off the Highbreed's invasions on his territories.

Vilgax returns in *Vengeance of Vilgax*, having come back in a currently unknown way. His appearance has changed again; he is less cybernetically enhanced and his mouth is visible again. In addition to his traditional army of drones, he has been joined by new alien assistant, Psyphon. In order to justify his invasions, he now follows a Galactic law, fighting champions of a planet he attacks and defeating them to gain the right to legally conquer that world. In this manner, he conquered ten worlds, the last of which was Ultimos', and absorbed the champions' powers with the help of Psyphon, giving him powerful, new abilities. Despite all of his new-found power, Vilgax retains his obsession with the Omnitrix.

After his victory against Ultimos, Vilgax returns to Earth, where he quickly defeats Max and the Plumbers' kids. He does not however, choose to absorb their powers and instead uses them as messengers to Ben, challenging him in the rules of the Galactic Code, as he did with his other conquered planets, and leaving him 24 hours to answer, after which Vilgax will enforce his legal right to destroy Earth. After accidentally overloading the Omnitrix which mutates Kevin and recollects his escaped aliens, Ben 10 comes and fights him. After a long and feral battle, Vilgax eventually smashesChromastone to pieces, seemingly killing him. However, as Vilgax is about to take the Omnitrix, it reformats Chromastone's remnants into Diamondhead, bringing Ben 10 back to life. Due to both his age and the practice he had with this form during summers, Diamondhead proves to be strong enough to defeat Vilgax and the Galactic Conqueror, according to the laws, is forced to leave Earth with his army and never come back. He begrudgingly accepts his defeat, but vows to get revenge on Ben 10 one way or another.

Although Vilgax is manipulating the rules of the Galactic Code (which were established by the Galvans to prevent the massive loss of live) for an evil purpose, he does follow through on his adherence to them, despite his plan back firing.

In *Ghost Town*, Vilgax breaks Zs'Skayr out of his prison in exchange for the secrets of the Omnitrix. However, Zs'Skayr betrays him and invades his homeworld, Vilgaxia, by possessing the majority of its inhabitants and turning them in Ectonurite slaves. After vainly fighting the invasion, Vilgax escapes and reluctantly asks help from Ben and his team. After an uneasy alliance between them, they eventually reached Zs'Skayr and Ben 10 let himself be possessed in order to absorb him back into the Omnitrix. Though it was successful, Zs'Skayr took over Ben's personality, resulting in a battle between Ben's team, Vilgax, and himself (the former two parties now in contention over whether or not Zs'Skayr should be harmed while in Ben 10's body). Vilgax was eventually able to produce enough light to weaken Zs'Skayr, allowing Ben 10 to take over again and turn back to human form. Vilgax then allows Ben 10, Gwen Tennyson-Levin and Kevin 11 to leave, having earned their freedom for their help. Vilgax later gloats to himself about having acquired the secrets of the Omnitrix.

In *Primus*, Vilgax attacks the planet, Primus, causing the Omnitrix to teleport Ben, Gwen and Kevin to the world as well. The Omnitrix leaves Ben's wrist to find Azmuth. Azmuth uses the Omnitrix himself to fight Vilgax and protect Primus. Vilgax defeats Azmuth and takes the Omnitrix from him. As the device has recalibrated since he last operated it, Vilgax no longer knows how to use it, forcing him to ask Ben for the information in exchange for his friends' lives (after taking them captive).

Ben 10 activates the Omnitrix, turning Vilgax into Goop, but Ben 10 steals the artificial gravity disk and turns it off; leaving Vilgax as an immobile puddle. Ben takes the Omnitrix out of the puddle of Vilgax as Goop, changing Vilgax back to normal and then re-attaches the device to himself. Cannonbolt throws Vilgax into the Codon stream (which is full of the DNA the Omnitrix accesses to transform its wearer) where he grows considerably larger. Ironically, at the end of this episode Ben 10 throws Vilgax into space after changing into Way Big similar to Vilgax's defeat at Ben 10's hands 5 years prior. It has been revealed by Dwayne McDuffie that this was intentional. Some time after, Vilgax returns to his usual size.

Vilgax returns in *The Secret of Chromastone* searching for Tetrax Shard, who had stolen back the crystal Vilgax used to destroy Petropia (which Tetrax had originally sold to Vilgax). Tetrax had discovered (unknown to neither him, nor Vilgax, at the time of the destruction of Petropia) that the crystal serves as a back-up for Petropia and its people. Vilgax tracks Tetrax to Earth and demands he turn over the crystal he stole, only to discover that Tetrax had given it to a freedChromastone in order to restore Petropia (mistakenly revealed by Kevin 11). Vilgax leaves Earth and travels to Sugilite's location only to discover the newly restored Petropia. Outraged that "*his crystal*" was stolen to revive a "*dead world"*(one he destroyed), Vilgax beats Sugilite (who he compares to little more than a common thief). Sugilite begs Vilgax to let him revive the Petrosapiens and pleads for mercy, but Vilgax reveals he has no mercy to give. Vilgax mercilessly beats the helpless Sugilite, until he is confronted by Ben's Team and an angry Tetrax. Vilgax uses his shield to stop Tetrax's projectiles and then removes the "*Petropian backup crystal*" from Sugilite's head only to discover its energy had been used up. Seeing that the crystal was no longer useful, Vilgax throws it away and leaves Petropia (seeing it as nothing more than a lifeless planet and no threat to him) in disappointment. However unknown to Vilgax, Sugilite created a second backup crystal which is used by Ben to restore the planet's population. Tetrax later tells Ben 10 he plans to settle the score with Vilgax, but Ben wonders how, given Vilgax's current invulnerability, he'll be able to do so. Vilgax returns to his home on Vilgaxia and is outraged to find out he had caught Ben 10's cold. The episode ends with Psyphon handing Vilgax a tissue.

Vilgax reappears in the series finale *The Final Battle*, wherein he teams up with Albedo, claiming he just wants to kill Ben Tennyson and will let the Omnitrix go to Albedo so he can regain his Galvan form. Though the plan is successful, Ben 10 escapes thanks to Max's help and Vilgax ultimately betrays Albedo, taking him prisoner and keeping the Omnitrix for himself in order to give its powers to his army of Bioids (robots synchronized with the Omnitrix for the purpose of assuming the alien form selected from the device).
Ben 10 confronts Vilgax again and activates a lessened form of the Omnitrix's self-destruct mode (one that will destroy the device itself, without destroying the Universe along with it), hoping Vilgax will give it over before it detonates. Vilgax doesn't take his threat seriously however, allowing the Omnitrix to detonate. Enraged, Vilgax programs his ship to crash into Bellwood and attacks Ben 10 and the others. Ben 10 then frees Albedo and forces him to give up the Ultimatrix (which Ben 10 then equips himself with). While Ben 10 fights Vilgax as Ultimate Swampfire, Max and Gwen Tennyson-Levin successfully cause the ship to crash in the ocean before reaching Bellwood. Now in the water, Vilgax reveals his "true form", transforming into a giant monstrous, octopus-like creature. He intends to swallow Ben 10, but the hero escapes, leaving Vilgax behind as his ship explodes. However, Ben 10, knowing that Vilgax has survived far worse, suspects that he may return.

### Ultimate Alien

In *The Big Story*, Ben 10 tells Jimmy that he has nightmares about Vilgax.

In *Ben 10,000 Returns*, it is revealed by future Ben 10 that Vilgax is alive and will return.
Vilgax returns in *The Flame Keepers' Circle*, where he reveals that he had survived the events of his last battle with Ben. After surviving the explosion created by the fusion reactor on board his ship, Vilgax was left in a weakened state and thus unable to return to his usual form. He eventually washed up on a beach and was discovered by humans who made him into an exhibit at a traveling carnival. Although he was subjected to the indignity of becoming a spectacle for the masses, Vilgax took advantage of the situation and slowly regained his strength until a group of financialists liberated him. The Flame Keeper's Circle discovered him in his squid-like form, believing the intergalactic conqueror to be the legendary "Diagon" - an alien of wisdom and knowledge. Guided by the prophecies of their founders, the group began to worship Vilgax in the hopes that he would bring about a "Golden Age" of prosperity to the Earth through the use of alien technology. Vilgax is eventually discovered living in a fish tank in the group's main office building while Ben 10 is out gathering information about the cult, during which he tells his arch nemesis of his plans to reclaim his empire once he gains access to a spaceship. Ben gets this information to Kevin and Gwen, who manage to disable to the Plumber's Ship that had been stolen by the cult. They attempt to expose Vilgax's true identity to the Flame Keeper's Circle, but the members remain unconvinced. Echo Echo then shatters the tank holding his nemesis, swearing to stop him if Vilgax makes another attempt to leave the Earth.

In *A Knight to Remember*, Vilgax is seen sulking in his aquarium, demanding that the Flame Keeper's Circle give him a means to regain his power. He learns from them that Diagon's Heart was the main source of the creature's power and quickly orders them to take him to it so that he may claim it for his own. During the ensuing battle between Diagon's cult and the Forever Knights, the weakened Vilgax stops Sir George's attempt to destroy the heart and removes the First Knight's sword from it. The power unleashed from the weapon subsequently allows the intergalactic conqueror to regain his normal form, covering him with knight armor and allowing him to absorb the heart. The Flame Keeper's Circle realizes that their leader is a fake, but Vilgax uses his newfound powers to knock out his former followers and the Forever Knights in a single blast. Winston, now possessed by Diagon, then tells Vilgax that he can gain even greater power by breaking the seal in which the Lucubra was captured. Unaware that Diagon is only using him to gain his own freedom, Vilgax travels to the site and begins to slash away at the stone with Old George's sword. Ben 10's team figures out the truth and arrives to stop him, but Vilgax ignores their advice. Ben 10 then transforms into Eatle to fight him, but Vilgax proves too powerful and repels him with minimal effort, quickly using his heat vision to take down Kevin 11 as well. He then opens the seal and gets sucked into Diagon's dimension, leaving behind the sword and armor.

In *The Beginning of the End*, it is revealed that while Vilgax was in Diagon's dimension, Diagon made him his most powerful follower and he became the Herald of Diagon. When Sir George arrives at the seal, Diagon sends Vilgax to fight him. The other Forever Knights attack Vilgax, but he easily defeats them, leaving George alone. After Heatblast arrives, Vilgax then moves forward towards to the seal and attempts to break it; though in remains intact, the cave wall around it crumbles and opens a void to Diagon's dimension.

In *The Ultimate Enemy: Part 1*, Vilgax is still battling Heatblast and Sir George. Kevin and Gwen arrive and battle Vilgax; he attacks The Seal, then Ben 10, Gwen Tennyson-Levin, George and Kevin 11. He fires at the team, however Gwen Tennyson-Levin is able to shield them with a large mana field. Unfortunately, Vilgax has been able to damage the seal just enough, so that Diagon is able to produce a wave that transforms every living person on the planet into an Esoterica. Ben 10, Gwen Tennyson-Levin, Kevin 11 and Sir George are not effected due to Gwen Tennyson's mana field, as well as Julie Tennyson, whom Ship shielded from the wave by transforming into a suit around her. Every being on Earth is now under Diagon's control. Heatblast then melts the rock under Vilgax, who gets trapped and cannot escape the rock. He asks his master Diagon to give him more power, so that he may free himself and break the seal. Diagon agrees and Vilgax glows blue and grows stronger as he breaks out of the rock. He attacks Ben 10 and George and Ben 10 transforms into Eatle to fight him. After a long and difficult battle, Eatle is able to ram into Vilgax and send him flying. Vilgax breaks through several buildings and crashes into the top of a pyramid.

While George and Ben 10 think that he has been defeated, Vilgax raises up and breaks the top off of the pyramid, then throws it at them. Eatle is able to cover and protect George, but the large building falls on top of them. Vilgax crosses the wreckage and approaches the seal, then starts to destroy it. As Vilgax is attempting to destroy the seal, Diagon grows angry at him, for the power he was given was more than enough to break the seal. Eatle and George rise from the wreckage and begin to attack Vilgax. Ben 10 mentions to Vilgax that he is not a true servant of the Diagon and he only wants something out of it for himself. Vilgax is angered and attacks Ben 10 again. He successfully attacks Ben 10 and George, knocking them away. Ben 10 transforms into Humungousaur and runs towards Vilgax. Vilgax manages to knock Humungousaur away again and he nearly falls onto Kevin 11, who has arrived in the car to tell them that Diagon's got Gwen Tennyson-Levin, however she snapped out of it thanks to Kevin 11. Gwen Tennyson-Levin, George, Ben 10 and Kevin 11 now corner Vilgax and demand him to tell them how to stop the Diagon from coming and how to change everyone back from being Esoterica. Vilgax asks his master Diagon for more power, but is met with silence; a ship comes in from overhead and Psyphon exits it. Vilgax is angry that Psyphon is late, but Psyphon claims that gathering everything Vilgax asked for took more time than expected. Gwen Tennyson-Levin, George, Ben 10 and Kevin 11 approach Vilgax and Psyphon and Ben 10 transforms into Jury Rigg. However, a large tremor shakes the cave, and the seal glows with a bright light, as Diagon's voice booms and reveals that it has finally escaped. The seal glows brighter, then breaks apart. Both sides approach it and look into Diagon's dimension, but find nothing. They hear his booming laugh and run out to the cave's exposed ceiling to find Diagon in the sky, as he boasts that he is 'everywhere'.

In *The Ultimate Enemy: Part 2*, Vilgax and Psyphon suddenly disappear after Diagon freed himself. While Ben 10's team fight Diagon and his Esoterica, Vilgax waits for Psyphon to prepare the machine. After Diagon defeats Chromastone and kills Sir George, Vilgax and Psyphon return with the machine. Thinking it's a weapon, Diagon used his laser beams and tried to destroy it; however, the machine absorbs powers from other living beings and due to Diagon's essence being only power, he was fully absorbed within the machine. Psyphon fired the machine at Vilgax, and he absorbed all of Diagon's powers. Immediately he fires his laser beams at the team, but Gwen Tennyson-Levin teleports them to the Mount Rushmore Base.

Vilgax quickly finds them and sends his Esoterica to attack the base. After his Esoterica are defeated, he rips off the George Washington head and goes inside the base to fight Ben 10. Ben 10 learns how to use Ascalon and the two of them start to fight. Ben 10 stabs Vilgax and seals Diagon within the Ascalon. Defeated, Vilgax tempts Ben 10 into using Ascalon, the Ultimatrix and Diagon's power to rule the universe. Ben 10 begins to get tempted, but thanks to Julie Tennyson, Ship, Gwen Tennyson-Levin and Kevin 11 he snaps out of it and used Ascalon to turn every Esoterica to normal.

According to Matthew Kling, Vilgax did not lost the powers he stole at the end of **Ultimate Alien**.

In the Alien Force:Ex series, Ben 10 learns many things about Vilgax.He reforms and becomes Ben 10's best friend ever since in Ben 10 Alien Force:Ex 3 (*The Ultimate Enemy: Part 2).*

## Powers and Abilities

Before his augmentation, Vilgax didn't display any special powers or abilities, save 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's made clear he was seriously injured and widely believed to be dead at that time.

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 even further at will. Though it causes him great pain, the boosters give him enough strength to smash apart mountains with his bare hands. He proved to be quick, strong and durable enough to withstand Heatblast's most powerful heatwave, break through Stinkfly's goo and once stop a full-speed XLR8.Diamondhead once shattered his own fists against Vilgax. For most of the original series, Ben 10 was unable to defeat him alone, always winning thanks to external help. Once Ben 10 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.

**Enhanced Strength**

* Vilgax was able to easily defeat Humungousaur, Manny and Ultimos with a single punch (the impact of which created a large crater in the ground).

**Enhanced Durability**

* Vilgax could easily withstand Swampfire's fire blasts and Chromastone's lasers with no visible damage and recover within seconds from the Omnitrix's explosion.

**Flight**

* Vilgax can fly at high speeds.

**Space Survivability**

* Vilgax was also seen several times flying through space without a ship, where he was seemingly able to breathe without any visible equipment and pass through Earth's atmosphere with no damage at all.

**Optic Blasts**

* Vilgax can project red laser beams from his eyes, capable of making drastic arcs to assist the pursuit of their target.
* They were also shown to be incredibly fast, fast enough to catch up with Helen.
* They were also shown to burn Ectonurites.

**Enhanced Hearing**

* Vilgax can hear sounds that are too faint for normal hearing to detect.

**Wind Breath**

* Vilgax has breath so powerful that it can cause cyclone-like winds.

In *The Final Battle: Part 2*, he reveals his ability to turn into a giant octopus-like monster - which he referred to as his true form - in the ocean. He had this ability since the very beginning, and can transform at will.

After becoming the Herald of Diagon, he 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 Diagon's dimension and back at his, like the Esoterica.

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

After 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.

## Equipment

Vilgax could use the Ruby Ray of Ulo as a laser projector, and was able to considerably weaken Ultimos with one shot. 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 Ziegel 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, Jetray's neuroshock blasts or the guns of a spaceship. It can even let Vilgax cut clean through that same spaceship.

In *Vengeance of Vilgax: Part 2*, Vilgax used 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.

Vilgax's Sword can project energy beams or coat itself in flames or crystals able to refract Chromastone's energy blasts. 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 did not lose all of his equipment excluding his sword when he was arrested after *The Ultimate Enemy: Part 2*.

## Weaknesses

Vilgax is vulnerable to the cold virus.

If Vilgax is in his true form and becomes too weak, he cannot change back into his humanoid form.

Vilgax is highly durable, but he is limited to how much damage he can take.
