Ultra Boy (Jo Nah) is a superhero appearing in DC Comics, primarily as a member of the Legion of Super-Heroes in the 30th and 31st centuries. He gained his powers after being eaten by a whale-like beast in space and being exposed to large amounts of radiation while inside. His real name is derived from the Biblical figure Jonah, who also survived being swallowed by a "large fish" (often interpreted as a whale).
Ultra Boy has made limited appearances in media outside comics, with James Arnold Taylor voicing him in Legion of Super Heroes (2006).
