| Supervillain Animal Information
Radioactive Worm is a worm supervillain and enemy of Radioactive Man.
Radioactive Worm was caught up in the same nuclear explosion that turned Claude Kane III into Radioactive Man. This gave him mind control powers.
Radioactive Worm later made himself known to Radioactive Man. He commanded Radioactive Man, who at this point was Radio Man, to turn to him. Radioactive Worm then revealed that he had been the one behind Dr. Crab and Pneumatica. He had Dr. Crab build the Regresso Ray to turn Radioactive Man back into Radio Man so that he could mind control him. As Radioactive Worm was explaining his plan to Radio Man, Radio Man tripped over an unconscious Dr. Crab and fell onto the Regresso Ray, breaking it. This turned Radio Man back into Radioactive Man, which meant Radioactive Worm could no longer mind control him.
As Radioactive Man tried to grab Radioactive Worm, Radioactive Worm jumped away and landed on an exposed electrical wire from the Regresso Machine, which fried him.
