|Real name:||Sidney Wanamaker|
|Voiced by:||Michael Bell|
Sidney Wanamaker is a nerdy computer geek that once accidentally hacked into the Justice League Computer. Using information he learned from the Justice League computer, he created an anti-gravity belt, and became a superhero calling himself Captain Mystery.
However, he wasn't very good at being a superhero, as he was such a big bumbler that he constantly made things worse and screwed up allowing villains to escape. After an ordeal with Lex Luthor, the Super Friends finally convince Sidney to hang up his cape for good.
