Bouncing Boy is a fictional character in the DC Comics Universe, a member of the Legion of Super-Heroes in the 30th century. He is Chuck Taine of Earth, and he has the power to inflate like a ball and bounce. He received his powers when he accidentally drank a super plastic formula which he thought was soda pop. He first appeared in Action Comics #276 (May 1961).

He married fellow Legionnaire Duo Damsel in Superboy #200 and then left active service as a Legionnaire to become a Legion reservist, appearing only sporadically thereafter until Zero Hour. During his period as reservist, he and Duo Damsel were also in charge of training recruits to the Legion's Academy.

In the post Zero Hour reboot continuity, he was Charles Foster Taine (Chuck for short) who was the Legion's resident architect and engineer. He has not received bouncing powers in this continuity and was only an honorary member of the Legion. As a maintenance man, he once built a specialty vehicle called the "Bouncing Boy" which acted as a bouncing juggernaut, smashing anything in its way.

The name "Charles Foster Taine" is a reference to the classic 1941 feature film, Citizen Kane and its title character, Charles Foster Kane, though in his initial appearance he is simply named "Chuck Taine".

Bouncing Boy has not been a contender in any CBUB matches.
