When Hero arrives at the coliseum where he fought Enoch, he finds Overlord, where he reveals he was the one who leaked the footage to Will Harangue as revenge against Hero. He also has the Potis Altiare piece, so Hero chases him for it. Hero meets Overlord, he gets furious at him that he has one-upped him once again. When wondering how Psyphon knew of the existence of the Potis Altiare, Ultimate Alien Force: cosmic destruction thinks a Galvan could have told him. Azmuth appears saying the Galvan would die than tell their secrets. The cosmic storm has already arrived, and since there is still only one piece of the Potis Altiare, Hero has to get back to Rome in order to retrieve the artifact. When he remembers that the Omnitrix teleported them to the planet Primus, Azmuth then sets the Ultimatrix to reach the last piece of the Potis Altiare, and drags Hero along with it. After defeating Overlord, he passes out and the Potis Altiare piece is dropped into the sewers. When Hero goes in to retrieve it, he finds Psyphon grabbing it and running away with it. Hero chases Psyphon and escapes a room filled with bombs, then destroys Psyphon’s ship, and finally fights and defeats Psyphon. As Hero was about to actually finish Psyphon, he escapes with the cosmic storm, and the To’kustar finally arrives, demanding that Hero bring the Potis Altiare to him or else earth will be destroyed. Gwen and Kevin come to pick Hero up, where he now has all the pieces of the Potis Altiare (except for the one he destroyed in Tokyo during his fight with Cooper) and seems determined to fight the To’kustar to save the Earth. Hero goes to Japan to take down the To’kustar. While Ben tracks down the To’kustar, ben rescues citizens and destroys the rest of the R.E.Ds. When Hero finds the To’kustar, Vilgax attack becomes a full-sized Humungousaur to fight, but the To’kustar easily defeats him and tosses Ben into the ocean. The Ultimatrix has the pieces of the Potis Altiare attached to it, and Hero becomes Earth protector to become equal with the To’kustar. After defeating Evil Way Big he uses his powerful cosmic ray attack with the Potis Altiare. Jimmy then tells him about the new Sumo Slammers 3D movie. Evil Way Big, who is revealed to be Albedo, falls on the moon and eventually gets hit by Lu, Ultimate Alien Force: cosmic destruction.
