Synopsis for "The World's Finest, Part 6 of 6: Final Countdown"
Superman and Batman go to meet Toyman (Hiro Okamura) and it is revealed that he has created a giant mech. The giant mech is designed with its left side modeled after Batman and its right side modeled after Superman. Superman intends to pilot the mech up to the Kryptonite asteroid and destroy it. He hopes the mech will sufficiently shield him from the Kryptonite and he will survive, but his allies are unsure. Suddenly, Captain Atom appears and subdues Superman with a Kryptonite ring. The ring originally belonged to President Lex Luthor but had been in the possession of Batman and kept at the Batcave. When Batman asks him how he knew its location, Atom tells him that Superman told him in the future. Batman asks Atom how he can trust him considering he absorbed Major Force. Atom says he cannot, but also reveals that when he absorbed Major Force, he was sent to a possible future. There, a possible future Superman told Atom that their plan failed, and the world suffered a cataclysm. With Superman subdued and this information revealed, Batman has no choice but to agree. Captain Atom pilots the mech out of Earth’s atmosphere to destroy the asteroid. Meanwhile, it is revealed that Luthor’s failure to defeat and discredit Superman, combined with the injections of a mysterious superpower serum, have driven Luthor to insanity. Luthor publicly challenges Superman to single combat. Superman agrees and confronts Luthor. An epic battle ensues. During the battle, Luthor reveals to Superman that his technology has been supplied by Darkseid. Unbeknownst to Luthor, he is secretly being recorded with his admissions broadcast to the world. Luthor is defeated but escapes and disappears. Simultaneously, Captain Atom seemingly sacrifices himself to destroy the asteroid. Luthor’s confession leads to his impeachment. Pete Ross becomes the President of the United States. The pieces of the destroyed asteroid fall to Earth, bringing with them thousands of pieces of kryptonite. Worried for his friend, Batman mobilizes most of the heroes in the world to collect all the kryptonite they could find so that it will fall into the wrong hands.
