An intergalactic hunter named Khyber watches Ben from the shadows.

After stopping Bubble Helmet, Fistina, and Liam from blowing up Mr. Baumann's superstore, Ben and Rook discover an underground alien city named Undertown where they discover that Psyphon is behind the protection racket. At the same time, Khyber sends his pet in the form of Buglizard to hunt Ben.

While Khyber struggles to control his dog's transformations, Dr. Psychobos tells Malware that he will need a part of the Omnitrix to fix it. This causes Dr. Psychobos to infiltrate the Plumbers' base on Earth and steal a part from Ben's Omnitrix causing it to malfunction. The malfunctioning of the Omnitrix causes its powers to leak into Psyphon, Bubble Helmet, Fistina, and Liam giving them abilities very similar to the Omnitrix aliens.

Professor Paradox helps mainstream Ben 10 to find a team of good Bens (consisting of the rich, famous Ben 23, a 10-year-old "Gwen 10" and mainstream Ben's futuristic self, Ben 10,000) to fight back and save normal Ben. Things take a turn for the worst when Vilgax uses a Chrono-sapien time bomb to wipe out Ben in every other dimension from the normal Ben. Before disappearing, Mainstream Ben gives his Omnitrix to Normal Ben. Paradox brings the only Ben to survive, Normal Ben, and tells him his only hope is to back to the beginning and become Ben 10 when he should have.

Normal Ben and Professor Paradox return to the point where the Ben 10 Multiverse began: when original Ben first wore the original Omnitrix at that summer camp grounds years ago.

With Ben annoyed at no longer seeking help or getting respect for helping, he "quits" being a superhero.
