Ben 10: Omniverse 8x10

Ben and Rook follow Maltruant through the time stream. Ben has an adventure with George Washington, in 1773, fighting Maltruant and Vilgax. After defeating Vilgax, Ben and Rook chase Maltruant in the time stream to the beginning of time itself onto the starship of the Contemelia (the creators of the Annihilaarg) where Maltruant attempts to create a universe of his own using his own Anihilaarg. In a climactic battle, at the beginning of time Ben nearly dies trying to stop Maltruant from building his own universe but then it is revealed that the Omnitrix has a fail-safe to prevent its keeper from dying.
