Mazinkaiser

Dr. Hell returns with a renewed army of Mechanical Beasts, overwhelming Kouji Kabuto and Tetsuya Tsurugi in a brutal assault. Mazinger Z is captured and twisted into the enemy's Ashura Mazinger, while Great Mazinger is badly damaged and Kouji vanishes in the chaos.

With the Photon Power Laboratory facing destruction and Tetsuya pushed beyond his limits, a mysterious machine suddenly enters the battlefield and obliterates Dr. Hell's forces. Its name is Mazinkaiser, an overwhelming super robot whose arrival gives humanity a new weapon for the war ahead, if Kouji can master the immense power placed in his hands.
