Plot
Myaxx informs Azmuth that someone has stolen the Ultimatrix, Azmuth's newest creation. Albedo has it and has completed the Ultimatrix in order for him to regain his original form but the Ultimatrix only has Ben's available aliens. Vilgax then appears out of nowhere and makes an alliance with Albedo, saying he doesn't want the Omnitrix anymore and just wants to kill Ben and take over his world.

In the future, a few people wearing Plumer gears see 2 dead bodies. A woman named Summerfield said that those bodies are Ben Tennyson and the 7th Doctor, meaning that it too late.
