Mazinger Z: Koji to the Rescue of Superalloy Z

Koji Kabuto, pilot of Mazinger Z, has saved the world countless times from the evil Dr. Hell. But now, a new threat endangers not only his robot, but the fate of humanity itself.

A group of Dr. Hell’s henchmen infiltrates the Photon Power Laboratory. During the assault, they steal secret plans that reveal the location of Japanium deposits—the rare mineral used to produce superalloy Z, the material from which Mazinger Z is built.

They also seize fragments of superalloy Z stored at the research center and sabotage the robot’s photon reactor, leaving it completely disabled.

Taking advantage of Mazinger’s shutdown, the villain plans to use the stolen plans—which reveal where Japanium can be found—along with the fragments of Alloy Z already in his possession, to build a mechanical colossus with the same power as Mazinger: a machine capable of crushing humanity and paving the way for global domination.

Koji must cross multiple battlefields, face Dr. Hell’s forces, Baron Ashura, Count Brocken, and finally the evil mastermind himself, to recover the stolen fragments before they are used to destroy Mazinger and enslave the world.

The final battle is about to begin!
