Plot
During a battle with Dr. Animo, Ben Tennyson's destruction of the scientist's "DNA bomb" accidentally sets off a self-destruct protocol in the Omnitrix. Its activation alerts Tetrax Shard, an intergalactic bounty hunter and one of Ben's allies, who travels with his alien slime-like pilot Gluto to Earth in order to retrieve Ben. He explains the situation to Ben, who hasn't figured out the meaning of the countdown. He leaves Gwen and Grandpa Max behind, not wanting the latter to be recognized during their trip, but Gwen sneaks onboard anyway. Using the advanced medical equipment onboard his ship, Tetrax finds the DNA signature of the Omnitrix's creator, Azmuth, and tracks him to a prison facility called Incarcecon. During the journey, Tetrax hopes that Ben will stop being a hero when the Omnitrix stops the countdown and Azmuth shuts it up for good. Ben is upset that he'll never be a hero again. After staging a breakout, they free a female Chimera Sui Generis (Vilgax's species) named Myaxx, who is Azmuth's assistant; she had switched her DNA signature for Azmuth's when he refused to give her credit for helping to create the Omnitrix. Myaxx is also unable to disable the self-destruct, which will not only kill Ben, but destroy the entire universe as well. Myaxx knows where to find Azmuth, and leads them to Xenon, where he is currently hiding. However, Ben's arch-nemesis Vilgax, who has escaped from the Null Void, also picks up on the Omnitrix's self-destruct signal and, along with Tetrax's rival SixSix, hunts down Ben in hopes of stealing the Omnitrix for himself.
