The threat of mutant monsters wasn’t just in America, but world wide. To counter the threat, the Japanese forces developed the Robo-Yeti in secrecy. In order to keep it a secret, the machine was dressed in an Albino Yeti costume, making it appear as if just another mutation. When people began to vanish around Mount Fuji, the robot was sent into action and came across Godzilla. Thinking he was responsible, Dr. Ifukube, his creator, had the robot go on the attack. Watching on in awe, H.E.A.T. soon discovered the Albino Yeti was no living being, but instead a robot. Godzilla’s atomic fire blasted it and quickly spread, burning away the fake skin and fur and revealing the entity underneath.
After Godzilla unleashed his green atomic fire on the Albino Yeti, stripping it of it's disguise, he found himself faced with a formidable opponent. A juggernaut of steel, an ultimate anti-mutant mech, the Robo-Yeti was relentless. Firing at Godzilla with missiles and using whip-like cables that could conduct electricity, it seemed as if Godzilla met his match. H.E.A.T. was arrested by the Japanese Self-Defense Force and made to watch as Robo-Yeti and Godzilla fought on. Trying to convince them that it wasn’t Godzilla whom was snatching up the locals, their pleas fell on deaf ears until King Cobra made his presence felt in a big way. It suddenly attacked the camp, forcing Dr. Ifukube to call her robotic creation back to camp where it was attacked by the snake and damaged by its powerful coils. Godzilla didn’t manage much better and was blinded by the serpent's toxic glue.
As the snake made a line for Tokyo, the Robo-Yeti was fixed with help from Craven and N.I.G.E.L. and sent into battle. Using Elsie’s chemical to breakdown and free captured people from the glue-like venom, the Robo-Yeti was once again face to face with King Cobra, and this time there would be no mercy! The snake coiled itself around the machine and squeezed, crushing its body like a tin can and ruining years of work, leaving Godzilla as Tokyo’s last hope.
