Bouncing Boy was a member of the Legion of Super-Heroes in the 30th century. He had the ability to inflate himself like a ball and bounce, granting him extraordinary resistance to injury while inflated. He often uses his power offensively by slamming himself into opponents.
When the Fatal Five took mental control over several members of the Legion, Bouncing Boy and Brainiac 5 were the only members of the team not enslaved. Via time travel, Brainiac used his genius to send a time sphere back to the early 21st century and enlisted the aid of Supergirl, Green Lantern and Green Arrow to help combat the Fatal Five. While Bouncy and Lantern were subsequently captured in battle, the other three escaped and managed to defeat the Five and liberate their teammates. In gratitude, Bouncy made all three Leaguers honorary members of the Legion.
