## Plot

Ten years after the end of the war against Dr. Hell and his Mechanical Beasts, the world lives in an era of peace thanks to the development of photonic energy for peaceful purposes. Mazinger Z's pilot Koji Kabuto has become a distinguished scientist, after his father and grandfather, while Sayaka Yumi is now the director of the Photon Research Institute, after her father, Dr. Yumi, became the Prime Minister of Japan. Great Mazinger's pilot Tetsuya Tsurugi is still in the military and married to Jun Hono, who is expecting their first child. Koji's younger brother Shiro is also a military mecha pilot.
While constructing the institute's new building, they find an enormous robot buried beneath Mt. Fuji, which they codename Infinity. When Koji comes to investigate, a girl emerges from the inside. Lisa is the robot's main control unit, a 91% organic AI with feelings. Shortly before, the presumed dead Dr. Hell attacks the institute with new Mechanical Beasts, as well as his henchmen Baron Ashura and Count Brocken, and steals the Infinity, using a captured Tetsuya and Great Mazinger as improvised activation key, since he was unable to get Lisa. Lisa reveals that the final power of the Infinity is the Goragon, the ability to exchange their universe with another, by causing a forced quantum overlapping. Dr. Hell plans to use it, as he believes this world is not worth existing.
Dr. Nossori and Dr. Sewashi use a giant photonic energy 3D Printer to repair and upgrade the original Mazinger Z (which was hidden at the old Photon Research Institute). Koji and Lisa, in the refurbished Mazinger Z, infiltrate the invaded Photon Institute, battling the Mechanical Beasts inside. After defeating Baron Ashura and Count Brocken, Mazinger Z confronts Dr. Hell's robot, but is gravely damaged. Shiro rescues Great Mazinger, and they stop the Goragon countdown but Dr. Hell has a backup of Great Mazinger's activation code on his Bardos scepter and takes control of Infinity, activating Goragon.
In the adjacent dimension, Koji sees an alternate universe where Lisa is his and Sayaka's daughter. Lisa uses herself as a key to give Mazinger a power equivalent to Infinity's, by transmuting photonic energy into matter. Everyone on the planet gives their photonic energy to Mazinger Z, and Koji punches Infinity with Dr. Hell out of the planet, where it explodes. Lisa disappears, assuring Koji they will see each other again. Meanwhile, Jun gives birth to her and Tetsuya's child.
Afterwards, Koji and Sayaka marry and they are seen walking with a child Lisa.
