Plot
After escaping, Ben expells himself from his friends for his failure because Vilgax has the Omnitrix. Ben then calls on Azmuth for help and after their conversation, Ben eventually returns to his friends with a plan. Ship brings the group on Vilgax's ship. Ben threatens that if Vilgax will not give him the Omnitrix, he will force it to self-destruct. Vilgax claims he's bluffing, so Ben is forced to self-destruct the Omnitrix so Vilgax cannot use it. Meanwhile, after the Omnitrix is destroyed, something strange and painful happens to Kevin. He then turns back into his original human form, as it was the Omnitrix that kept him in his mutated form. Kevin apologized to Gwen for being mad at her while she's finding a cure. Then, he and Gwen kiss. Enraged, Vilgax begins to overload his hyper drive and aims it to crash on Bellwood, destroying it with everything within a hundred miles. Ben instructs Gwen, Julie and Grandpa Max to steer the ship away from Bellwood (but Psyphon tries to stop them, but was defeated) and tells Kevin the arrived Plumbers' Kids to help him fight Vilgax. Ben manages to convince Albedo to give him the Ultimatrix with Manny's assist and transforms into Ultimate Swampfire and almost defeats Vilgax. As the ship sinks underwater, it succumbs to the pressure of being below sea level and the ship starts to break, flooding the inside with water. Grandpa Max, Gwen, Kevin, and Julie escape, while Ben is left to fight Vilgax. Vilgax, in his natural element, turns into a giant squid-like creature and tries to eat Ben. Meanwhile, on top of the water, Max Tennyson, Gwen, Kevin, Julie, Ship, and the Plumbers' Kids see an explosion come from under the water, because Vilgax's hyper drive was still activated. Ben survives and emerges as Ripjaws. Then they all hug, Azmuth appears congratulating Ben for defeating Vilgax and lets him keep the Ultimatrix and the show ends.

Trivia

 * Vilgax's goal of having an entire army powered by the Omnitrix(first mentioned in the Ben 10 episode, Secrets) finally comes to fruition.
 * The self-destruction of the Omnitrix causes Kevin to finally return to normal, as it was the Omnitrix's energy that had been keeping him in his mutant form all along. Albedo has the same experience and has Ben's form but when the Omnitrix self-destructed, he did not return to his original form, like Kevin did. This is possibly due to Azmuth, who said that Albedo is stuck in his new form as punishment for making a second Omnitrix.
 * This marks Ripjaws' first appearance since Ben 4 Good Buddy.
