Vilgax's History
In The Beginning of the End, it is revealed that while Vilgax was in Dagon's dimension, Dagon made him his most powerful follower and he became the Herald of Dagon. When Sir George arrives at the seal, Dagon 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 Dagon'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, Gwen, George, and Kevin. He fires at the team, however Gwen is able to shield them with a large mana field. Unfortunately, Vilgax has been able to damage the seal just enough, so that Dagon is able to produce a wave that transforms every living person on the planet into an Esoterica. Ben, Gwen, Kevin and Sir George are not affected due to Gwen's mana field, as well as Julie, whom Ship shielded from the wave by transforming into a suit around her. Every being on Earth is now under Dagon's control. Heatblast then melts the rock under Vilgax, who gets trapped and cannot escape the rock. He asks his master Dagon to give him more power, so that he may free himself and break the seal. Dagon agrees and Vilgax glows blue and grows stronger as he breaks out of the rock. He attacks Ben and George, and Ben 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 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, Dagon 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 mentions to Vilgax that he is not a true servant of the Dagon, and he only wants something out of it for himself. Vilgax is angered and attacks Ben again. He successfully attacks Ben and George, knocking them away. Ben transforms into Humungousaur and runs towards Vilgax. Vilgax manages to knock Humungousaur away again, and he nearly falls onto Kevin, who has arrived in the car to tell them that Dagon's got Gwen, however she snapped out of it thanks to Kevin. Gwen, George, Ben and Kevin now corner Vilgax and demand him to tell them how to stop the Dagon from coming, and how to change everyone back from being Esoterica. Vilgax asks his master Dagon 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, George, Ben and Kevin approach Vilgax and Psyphon, and Ben transforms into Juryrigg. However, a large tremor shakes the cave, and the seal glows with a bright light, as Dagon's voice booms and reveals that it has finally escaped. The seal glows brighter, then breaks apart. Both sides approach it and look into Dagon's dimension, but find nothing. They hear his booming laugh, and run out to the cave's exposed ceiling to find Dagon in the sky, as he boasts that he is 'everywhere'.
In The Ultimate Enemy: Part 2, Vilgax and Psyphon suddenly disappear after Dagon freed himself. While Ben's team fight Dagon and his Esoterica, Vilgax waits for Psyphon to prepare the machine. After Dagon defeats Chromastone and kills Sir George, Vilgax and Psyphon return with the machine. Thinking it's a weapon, Dagon used his laser beams and tried to destroy it; however, the machine absorbs powers from other living beings and, due to Dagon's essence being only power, he was fully absorbed within the machine. Psyphon fired the machine at Vilgax, and he absorbed all of Dagon's powers. Immediately he fires his laser beams at the team, but Gwen 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. Ben learns how to use Ascalon and the two of them start to fight. Ben stabs Vilgax and seals Dagon within the Ascalon. Defeated, Vilgax tempts Ben into using Ascalon, the Ultimatrix and Dagon's power to rule the universe. Ben begins to get tempted, but thanks to Julie, Ship, Gwen, and Kevin he snaps out of it and used Ascalon to turn every Esoterica to normal.
