Rodak sends three black liquid blobs that can impersonate humans to steal a secret formula. They head to the Research Center, where a conference is taking place with world scientists and a member of the United Nations. Changing from men to liquid blobs, the aliens get by the conference guards and steal a formula that eats vegetation, the substance which Lugo Men are made of. Tom Mura is assigned to follow up on the scientific conference. The Lugo Men overhear a scientist telling Tom that the formula Rodak stole was not real, but only a decoy. Rodak sends his latest creation Noronda (Stopgon) to Earth… a giant creature made of metal, which can paralyze any type of machinery. Gam and Mikko fly to the last reported location of Noronda and confront the creature. Gam flies around and around the monster’s head. Getting dizzy, Noronda falls backwards and shatters. But, to Gam and Mikko’s surprise, the creature’s metal parts reform. Noronda lives again!
