Radioactive Man-Beta is a version of Radioactive Man from the Betaverse.


Radioactive Man-Beta was pulled through an energy field into Radioactive Man's universe. When Plasmo tried to open up a portal to the Betaverse as the heroes theorized that was where the energy rift originated, they found nothing, with Radioactive Man-Beta thinking that his universe was gone. The heroes then got pulled into the negative universe where they fought against Nega-Pneumatica. As they were trying to escape back to Radioactive Man's universe, Nega-Pneumatica came at the heroes. Radioactive Man suggested that Radioactive Man-Beta stay behind to stop her as he has lost everything already, but he refused. He then helped the other heroes defeat Nega-Pneumatica.

Shortly after, the heroes found out that they were in a government facility and that it was all a trick using holograms and other technology. Radioactive Man-Beta was annoyed at Radioactive Man for suggesting that he stay behind, since his universe was still around after all. He then used Dr. Broome's Trans-Spatial Stairclimber to go home.
