Jo Nah of Rimbor was flying his one-man craft near his homeworld when he was swallowed by an ultra-energy beast. After being rescued, he learned that exposure to the radiation while inside gave him a number of superpowers, though he could only use one of them at a time. He soon joined the Legion of Super-Heroes, and later became romantically involved with Phantom Girl.
