Plot
The Triceraton Republic launches a massive invasion of Earth, believing Professor Honeycutt to be hiding on the planet. After wreaking havoc on the planet, they are convinced to leave by Donatello, who reveals Honeycutt's departure, only for Honeycutt to return to Earth, intending to surrender himself to the Triceratons. Honeycutt and the Turtles are abducted by the Earth Protection Force, led by Agent Bishop, who has allied with the Federation. While Traximus deposes Zanramon, Honeycutt sacrifices himself to upload a computer virus to the Triceraton and Federation fleet. Traximus jails Zanramon and Blanque and declares a new era of peace. Having observed the damage that has been done to Earth from the sidelines, Shredder uses his Oroku Saki persona to help in the reconstruction of New York, secretly salvaging Triceraton technology for an unknown purpose, while Bishop schemes to create an army of super-soldiers.
Splinter and the Turtles are visited by "Ultimate Drako", a fusion of Ue-Sama and Drako, who wield Lord Simultaneous' Time Scepter, and scatter the group across time and space. Michelangelo arrives in a world where the Turtles are superheroes fighting a villainous Splinter, Raphael enters the world of the Planet Racers franchise, Donatello suffers in an alternate timeline where Shredder has conquered the Earth, and Leonardo arrives in Miyamoto Usagi's dimension. With Usagi's help, Leo travels to the Battle Nexus and is able to reunite his brothers and Splinter and defeat Ultimate Drako. Though the duo is separated and Drako perishes, Ue-Sama is restored to a youthful form and reunited with his father.
After receiving a vision of Shredder departing Earth to conquer the Utrom home world, Splinter rallies the Turtles, Casey Jones, April O'Neil, Leatherhead, and Honeycutt (who were revealed to have survived their supposed deaths) to storm Shredder's stronghold on the eve of his departure in a massive spacecraft. Bishop also enters the fray with Stockman on his side, but Shredder is able to lift off with Karai and Dr. Chaplin, with the Turtles and Splinter stowing away. As Bishop continues to assault the ship in space, Shredder viciously wounds his foes, who decide to sacrifice their lives by detonating the ship's power core to kill Shredder. The Utroms arrive just in time to save them all and find Shredder guilty of numerous war crimes and atrocities, banishing him to a desolate asteroid.
