The Four-Armed Terror
Any one of a group of yellow-skinned humanoid creatures, grown from stolen human DNA, that feed on nuclear radiation.
An army of Four-Armed Terrors, described individually as "in the shape of man, but ... not man" (SPJO No. 137, Apr 1971: "The Four-Armed Terror") and possessed of super-strength, is unleashed on the DNA Project by Simyan and Mokkari, two agents of Darkseid, in April 1971. After a battle involving the Golden Guardian, the creatures are led by Superman, "like maddened lemmings," into a pit below Metropolis where they are destroyed in a nuclear explosion (SPJO No. 138, Jun 1971: "The Big Boom").
