Biography EditCaptain Dark is a soldier in the Red Ribbon Army, and subordinate to General Blue when he makes an appearance early in the General Blue Saga of Dragon Ball. While he goes by the title of lieutenant in his first appearance, it is likely that the title of captain by which Dark is referred to in his second appearance is more accurate, as he is a low-ranking soldier in the Red Ribbon Army and thus is not likely in the league of a lieutenant. He is obese, which General Blue disapproves of, and carries a whip which he uses to enforce his very strict mannerisms. Still, Dark is shown to be fairly easy-going, which results in his being the first in the General Blue regiment to be defeated.
When General Blue assigns his unit into two "companies", Captain Dark is granted control of "Company B". His team travels the ocean to Kame House, where their mission is to capture Master Roshi and confiscate one of the Dragon Radars they are under the impression he has invented (although this respect goes to Bulma). When Dark asserts that he cannot divulge any information or the Dragon Radar through Roshi, he prepares to use force, cranking his whip, unaware that Master Roshi is a professional martial artist and one of the strongest humans alive. Captain Dark is soon defeated with a single punch to his stomach, and Company B's defeat follows soon after.
