Ben 10 Fan Fiction Wiki:Archive/Vilgax

Vilgax is an intergalactic alien conqueror; a Chimera Sui Generis from the planet Vilgaxia, who serves as Ben's biggest archenemy and most recurring opponent. He was introduced in the first episode of the Original Series, And Then There Were 10, and has since appeared in almost all seasons of the Original Series, as well as season 3 of Alien Force. He was originally the primary antagonist.

A vicious galactic warlord known as "the most dangerous being in the galaxy," Vilgax's goal is to get the Omnitrix and use it to create an army of shape shifting drones able to conquer every planet. Though he originally chased Ben only because of this, and had few concern about his fate once he would get the Omnitrix, the several failures the boy has caused him, as well as an imprisonment in the Null Void, causes him to grow hating him, so much that, in his last appearances, he seems to want to kill him nearly as much, if not more, than to get the Omnitrix.

Vilgax is one of the most feared beings in the universe, having conquered 10 worlds, destroyed five planets, and created a black hole. In fact, he is so feared, that almost no biological life form is willing to work for him, forcing him to use robots for his entire crew, though he is able to find mercenaries willing to work for him for the right price.

In Ben 10: Negative Rising, it is revealed that Vilgax had to train an apprentice for a year, Vamor.



Appearance
In Ben 10: Protector of the Omniverse, he has his original series appearance (cybernetically enhanced version), but he has two big spikes on his shoulders. There are two small holes on his respirator for him to use his frost breath, and there are black cylindrical studs on his wrists. The red parts on his body are now Albedo red.

In Ben 10: Heroics Unleashed, he has his Alien Force appearance, but he has his respirator back, and he is more muscular. The red parts on his outfit is now silver.

In 10 and Beyond, he has his future self's appearance, but his skin is darker and there is red armor plating on his arms. His right eye is now blue, due to him losing it in a battle. It is also bigger than his left eye. The spikes on his left arm are now black. There are blue cables connecting from his back to his knees.

In Ben 10: The Omniwars, he has his Omniverse appearance, except the colors on his suit have been reversed. The bolts on his arms and legs are now silver. He no longer has bolts on his hands. The device on the sides of his head is now silver with red energy. He once again wears the equipment that he lost from Alien Force/Ultimate Alien, such as the Ruby Ray of Ulo, as seen in We The Conquerors. He has gained a second augmentation, so he appears to have more muscle than before.

In Ben 10: The Journey, he has his original series appearance, but with his Alien Force armor.

In Ben 10: Unbound, he has his Ben 10,000 appearance.

In Ben 10: Ultimate Omniverse, he has his Alien Force appearance, but with his original series (non- cybernetically enhanced version) armor.

In Ben 10: Nueverse, he has his Omniverse appearance, but with his original series (cybernetically enhanced version) head and facial features.

Original Series
Vilgax and his ship, the Chimerian Hammer, first appeared in the first episode 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 all destroyed because of the battle, causing him to be placed by his drones in a repair tank for healing, where he stays for most of Season 1. {C As the series progresses, Vilgax soon discovered the Omnitrix had been taken by someone

else (though yet ignoring who it exactly was), and made several indirect attempts to get the device back. This includes sending robots from his ship, hiring bounty hunters ( Tetrax, Kraab , and Sixsix ), and turning Earth's criminal Joey into the cyborg Rojo by fusing her with one of his drones. In the latter, he was able to shortly establish a telepathic link with Ben when the boy was fused to Rojo as Upgrade, warning him he was going to came 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 him his plan for the Omnitrix, and attempted to extract the Omnitrix from him, seemingly by sectioning his arm with alien tools. After several complications, including interruption from Gwen and Max and Ben losing control of his transformations, the Chimerian Hammer exploded, seemingly with Vilgax still aboard. In Truth, Max tells Ben and Gwen how he had a run in with Vilgax, who was stealing warheads from a military base when Max and his partner Phil showed up. In the resulting fight, Vilgax was strapped to a warhead by Max, and launched into his own ship. At that time, Vilgax was only slightly larger than a human man, compared to his now colossal size (an addition to his cybernetic augmentation). 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. He is found encased in ice by Kevin. Discovering Kevin'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. The battle lasts for a short time, and then Vilgax tries to send Ben to the Null Void. As Four Arms, Ben 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 to the Null Void without first obtaining the Omnitrix. It is the same reason why Ben found out that the battle with "Vilgax" is 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 Petrosapien's home world, and 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 to the point of calling him by his first name instead of his last name). He confronts Ben 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 access to a massive alien, Way Big, who hurls Vilgax into the outer realms of space.

Alien Force
Vilgax returns in Ben 10: Alien Force season 3, having come back by an unknown way. His appearance has changed again, as 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 the planet he attacks and defeating them to gain the right of legally conquer the planet. He conquered ten worlds by this way, the last of them being Ultimos' planet, and absorbed the champions' powers with the help of Psyphon, giving him new, powerful abilities.

After his victory against Ultimos, Vilgax returns to Earth, where he quickly defeats Max and the Plumbers' kids, but choose to not absorb their powers and instead to use them as messengers to warn Ben, challenging him in the rules of the Galactic Code and leaving him 24 hours to answer or he will destroy Earth. After accidentally overloading the Omnitrix, Ben comes and fights him. After a long and feral fight, Vilgax eventually smashes Ben as Chromastone, seemingly killing him. However, as Vilgax is about to take the Omnitrix, it reformats Chromastone's remnants into Diamondhead, bringing Ben back to life. Due to both 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 admits his defeat, but swears to have his revenge on Ben.

Although Vilgax is manipulating the rules of the Galactic Code established by the peaceful Galvans to prevent the massive loss of live, he still yields and returns to his home planet after being dealt a crushing defeat by Diamondhead.

In Ghost Town, Vilgax breaks Zs'Skayr/Ghostfreak out of his prison in exchange for the secrets of the Omnitrix. However, Zs'Skayr betrays him and invades his home world, Vilgaxia, by possessing all the inhabitants and turning them in Ectonurite slaves. After vainly fighting the invasion, Vilgax escapes and reluctantly asks help to Ben and his team. After an uneasy alliance between them, they eventually reached Zs'Skayr, and Ben let himself get possessed in order to absorb him back into the Omnitrix. Though this was a success, Zs'Skayr took over Ben's personality, resulting in a battle when Vilgax attempted to use the opportunity to kill his two enemies. Vilgax was eventually able to produce enough light to weaken Zs'Skayr, allowing Ben to take over again and turn back to human form. Vilgax then allows him, Gwen and Kevin to leave, but gloats to himself that now he has the secrets of the Omnitrix in his possession, this is a rather auspicious beginning.

In the episode Primus, Vilgax attacks Primus, causing the Omnitrix to teleport Ben, Gwen, and Kevin to Primus. The Omnitrix leaves Ben's wrist to find Azmuth. Azmuth uses the Omnitrix himself to fight Vilgax & protect Primus. Vilgax defeats Azmuth while he has the Omnitrix and takes it from him. However, since the device has recalibrated, Vilgax doesn't know how to operate it anymore, forcing him to ask Ben in exchange for his friends lives (after taking them captive). Ben activates the Omnitrix, turning Vilgax into a muscular Goop, but Ben steals the artificial gravity disk and turns it off leaving Vilgax as a puddle. Ben retakes the Omnitrix out of the puddle of Vilgax as Goop changing Vilgax to normal and then re-attaches the Omnitrix to him. Then Ben, as Cannonbolt, throws Vilgax into the Codon Stream (which is full of the Omnitrix DNA), where he gains Way Big's powers of size. Ironically, at the end of this episode, Ben throws Vilgax into space after changing into Way Big similar to Vilgax's defeat against Ben 5 years prior. It has been revealed by Dwayne McDuffie that this was intentional. Some time after, he returns to his original size.

Vilgax returns in The Secret of Chromastone where searching for Tetrax, who had stolen back the crystal Vilgax used to destroy Petropia (which Tetrax had originally sold to Vilgax). Tetrax had discovered (unknown either him or 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 freed Chromastone in order to restore Petropia (mistakenly revealed by Kevin). 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 planets population. Tetrax later tells Ben he plans to settle the score with Vilgax, but Ben wonders how given Vilgax's current invulnerability. Vilgax returns to his home on Vilgaxia and outraged to find out he had caught Ben's cold. The episode ends with Psyphon handing Vilgax a tissue. Vilgax reappears in the Alien Force finale, where he teams up with Albedo, claiming he just wants to kill Ben, and will let the Omnitrix go to Albedo so he can get back his Galvan form. Though the plan is successful, Ben escapes thanks to Max's help, and Vilgax ultimately betrays Albedo, making him his prisoner and keeping the Omnitrix for himself in order to give its powers to his army of Bioids. Ben then comes back and activates the Omnitrix's self-destruct mode so it will explode without destroying the Universe, hoping Vilgax will give it back before it does. Vilgax doesn't take his threat seriously however, causing the Omnitrix to be destroyed. In rage, Vilgax programs his ship to crash on Bellwood and attacks Ben and the others. Ben then frees Albedo and forces him to give him the Ultimatrix by threatening to destroy it as well. While Ben fights Vilgax as Ultimate Swampfire, Max and Gwen successfully make the ship crash in the ocean instead of Bellwood. Being now in his element, Vilgax reveals his "true form", transforming into a giant monstrous, squid-like creature. He intends to swallow Ben, but the hero escapes. Though Ben didn't see him escape before the ship explodes, he assumes Vilgax might come back, as he survived far worse. it is revealed that it was Vilgax's son Ricoronis Ben's been dealing with in season three and not the real Vilgax.

Ultimate Alien
According to Dwayne McDuffie, Vilgax may have been only severely injured due to the explosion, and may be recovering, like in the original series, and he is highly expected to return in Ben 10: Ultimate Alien and may team up with a lot of Ben's other enemies for revenge and may try to rebuild his ship, the Real Vilgax actually for real comes back and his son too! It is known that Vilgax only appeared in two episodes of Ben 10: Ultimate Alien and they are "A knight to remember" and "The flame keeper's circle."

Ben 10: Omniverse
In the episode Vilgax Must Croak, Ben and Rook are assigned to transporting Vilgax to maximum-security prison. It is also shown in an omniverse flashback that vilgax used to have squid pets, resembling lucabras.

Alternate Future
In the episode Ben 10,000, set twenty years in a now alternate future, Vilgax eventually escaped the Null Void by stumbling across a Null Void portal being opened on another planet. In Ben 10,000, it is revealed that Ben 10,000 fought Vilgax when he was 10 and lured him into an underground gas line. Ben's father, however, managed to activate the fire system and incinerated Vilgax. In this timeline, Ben didn't take any chances in defeating Vilgax when he was a boy. Dr. Animo resurrects Vilgax using his Transmodulator. He now has a retractable tentacle and is able to shoot organic bombs from his right wrist. His strength has been doubled. Despite that, both Vilgax and Dr. Animo are defeated by both future and present versions of Ben and Gwen. At the end, Ben defeats Vilgax by freezing him into a river using Articguana. It is unknown what became of Vilgax after this. Altough he was defeated this is one of his best forms.

200 years after the original series, Vilgax will face his final and utter defeat. He will perish and that will be the end of his intergalactic reign of terror.

Powers and Abilities
Before his augmentation, Vilgax's only seen abilities were tremendous agility and hand-to-hand combat skills, but he had no real powers. He also already had uncanny resistance to harm. He once survived a nuclear explosion at point blank range coupled with the destruction of his ship, though it's made clear he was seriously injured and it took such a long time for him to heal that many people thought he was dead until he came back afterwards.

After his cybernetic enhancements, he is much taller and is granted immense strength and near invulnerability, allowing him to easily leap above skyscrapers, survive in space, and smash apart mountains with his bare hands, along with being able to increase his strength at will, though it causes him great pain. He proved to be quick, strong and durable enough to stand Heatblast's most powerful fire wave, break through Stinkfly's goop and once stop XLR8 running. Diamondhead even once crushed his own fist on him when trying to hit him. For most of the original series, Ben was unable to defeat him in a fight, and always win either thanks to external help, until he got Way Big, who was the first alien of the Omnitrix to easily defeat Vilgax.

In Ben 10,000, Dr. Animo gives him a new, stronger form with enhancements, such as genetically implanted weapons (such as ropes and grenades in his right arm), bio-boosters, and knowledge of all of the future Ben's alien moves.

In Alien Force, 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. He is without his bio-boosters in his appearances in this series. Despite these new abilities, Ben is able to match Vilgax closer than ever before. Vilgax's new powers include:
 * Super Strength: Vilgax was able to easily defeat full size Humungousaur, Manny in a hand-to-hand fight, and Ultimos with a single punch (the impact of which created a large crater in the ground).
 *  Super 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. At one point in Vengeance of Vilgax, Max even shot him point-blank with a laser blaster, and still was unable to hurt him. Despite this, he is vulnerable the cold virus.
 *  Flight : Vilgax can fly at high speeds. 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.
 *  Laser Beams : Vilgax can project red laser beams from his eyes, capable of making drastic arcs to assist the pursuit of their target. While they don't seem powerful, they are powerful enough to knock Helen out, force Azmuth to revert from Humongousaur, and destroy the wind shields of Vilgax's ship. They were also shown to be incredibly fast, enough to reach a running Kineceleran. They were also shown to burn Ghostfreak, and his minions, in his natural state.
 * Enhanced Hearing: Vilgax can hear sounds that are too faint for normal hearing to detect (such as Ben sneezing from a considerable distance away). A weakness for this power is high frequency sound (such as Echo Echo's sonic screech), this weakness was never used however.
 *  Wind Breath : Vilgax has breath so powerful it can cause cyclone-like winds. His breath is shown to be powerful enough to put out a Pyronite's flames, do visible damage on Voliticus Biopsis, and even knock Kevin and Gwen out and send them flying.

Weapons
In addition to his seemingly organic/physical powers, Vilgax now wears various weapons and equipment, also supposedly taken from champions. These included: In the series finale, he reveals his ability to turn into a giant octopus-like monster (which he referred to as his true form) in the Ocean. According to Dwayne McDuffie, he had this ability since the very beginning, and can transform at will (though this form would probably be useful only in water). As a result of his transformation, Vilgax lost his stolen equipment, but somehow regained them when he was defeated by Ben in The Ultimate Enemy: Part 2.
 *  The Ruby Ray of Ulo : A red gemstone mounted on the back of his right hand. this gem could be used as a laser projector, and was able to considerably weaken Ultimos with one shot. According to Vilgax, Ultimos's ability to survive the shot was unusual, suggesting that most other beings would be either immediately killed or defeated.
 *  The Shield of Ziegel : A golden gauntlet on his left hand mounted with a yellow gem, able to generate a powerful personal force field to protect himself. 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 large spaceship. It can even let Vilgax cut clean through that same spaceship. In "Vengeance of Vilgax", he used the gauntlet as a taser, allowing him to touch and shock an intangible Big Chill. The only thing that was shown to shatter it was Diamondhead's exploding crystal shards.
 * An unnamed sword that can project energy beams and coat its blade in flames, or crystals able to refract energy blasts such as Chromastone's. Even without the flames or crystal, this sword is incredibly sharp, able to easily cut though stone, Chromastone's body, and even an entire space ship with a single stroke.
 * Raygun: Vilgax keeps a raygun in a holster on his right hip. He never uses it in the series, but he does in the Vilgax Attacks video game (he is even pictured using the ray gun on the Vilgax Attacks game cover).
 *  Light Energy Gloves : Vilgax once demonstrated the ability to coat his hands in light energy and use them as boxing gloves in Ghost Town.

Ben 10: Ultimate AlienEdit
Vilgax about to fire energy blastsAdded by UltimatexVilgax's enchanted laser beamsAdded by Starwars501stlegionFollowing the climatic battle with Ben, Vilgax lost all of his equipment, but retained his absorbed powers. After acquiring Ascalon he gains a suit of knight armor. As he put it, he now felt like he had more power then ever before. His new power includes the ability to fire off shock waves and his original and absorbed powers were amplified greatly.

After becoming the Herald of Diagon, he was given increased power and the color scheme appearance of a Lucubra. He is now stronger than ever, able to dispatch a group of Forever Knights and make Sir George almost exhausted in a fight. He can project and manipulate purple energy blasts from his hands and eyes, he can also move between Diagon's dimension and back to the same dimension at his will, like the Esoterica.

He used to have Diagon's power after he absorbed his essence into himself. His absorbed powers and his Lucubra powers were greatly amplified. He lost Diagon's Power and his Lucubra powers when Ben Tennyson used the Ascalon to take the power into itself and reverted back to normal.
