Bouncing Boy is a superhero appearing in American comic books by DC Comics, usually as a member of the Legion of Super-Heroes. Born on Earth as Chuck Taine, Bouncing Boy has the power to inflate like a giant ball and bounce around. This combination of invulnerability and velocity makes him a surprisingly useful combatant. Born without any powers, he received his abilities by accidentally drinking a super-plastic formula he believed was soda. Bouncing Boy is known for sharing a long-term romantic relationship with fellow Legionnaire Triplicate Girl of the planet Cargg, whom he eventually marries. In reboot Legion continuity, Chuck Taine is the Legion's mechanic.
