The Metal Men, Dr. Magnus and Colonel Casper land atop a skyscraper in search of a missing scientist called Ramsey Norton when suddenly a tremor rocks the building as a giant hand crashes through the roof grabbing a hold of Magnus and Platinum. The other Metal Men try to rescue them but the hand drags them into the building where it is revealed to be Professor Norton who has grown to giant size. He tells them how he was filling a giant Humanoid shaped container with the Chemicals from his failed experiments the last one from a failed growth formula. Which some how brought the creature which he calls Chemo to life. Chemo proceeded to hose him down with the growth formula which caused him to become a giant while Chemo made it's escape from the lab. After Norton finishes his tale he passes on. The building starts to collapse around Platinum and Magnus whom she saves.
