Primus

In the middle of a fight with another Techadon Robot, Ben, Gwen, and Kevin are unexpectedly transported by the Omnitrix to an alien planet called Primus. They soon discover that the planet is actually created by Azmuth, for it contains all the DNA samples from every life form in the galaxy. They soon learn that Vilgax is there to stop the Omnitrix at its source and that the Omnitrix's fail-safe program brought them there to defend the planet. Azmuth attempts to stop Vilgax, but loses and Ben is captured along with Kevin and Gwen. Ben offers to teach Vilgax about the Omnitrix if he lets Gwen and Kevin go. He turns Vilgax into Goop, shuts off Goop's artificial gravity projector and removes the Omnitrix from his immobile body. Ben then uses Way Big to throw a giant Vilgax (caused by immersion in the Codon stream) off the planet and, though it doesn't make up for damaging the Omnitrix, Azmuth thanking Ben by letting him keep it.
