Members The Red Ribbon Army's membership comprises humans, anthropomorphic animals, monsters, and robots. Its hierarchy is organized like a pyramid structure: its supreme leader is Commander Red, followed by his second in command and adjutant Staff Officer Black, who is in turn followed by commanding officers such as General Blue, and so on.

Black turns on Red and attempts to take command of the army and rename it the "Black Ribbon Army", only to be killed by Goku after he is able to wipe out most of the remaining Red Ribbon
