Captain Dark is a minor villain from Dragon Ball. He is a officer of the Red Ribbon Army, and the only high-ranked officer working under General Blue, though Blue is disgusted of him due to his obese appearance.
General Blue orders Dark and his henchmen to investigate Master Roshi's island, as at the time they believed Goku had a secret base of operations. Upon arriving there he interrogates Roshi and threatens him, but Roshi easily disposes of him and his henchmen. He is seen in DBGT when he escapes Hell, but goes back there.
