An African, Assistant Black worked as the right-hand of Commander Red, acting as his advisor. Soft-spoken, quick-witted, and clever, he helped him build the Red Ribbon Army and hired all of his officers, in order to search for the Dragon Balls so that Red could wish for world domination. Using a kind of radar on their headquarters, he could pinpoint the approximated location of the balls, then sending his men to find them. However, their officers were being defeated by Son Goku, who was also seeking the balls. After Goku defeats their hired assassin Tao Pai Pai, he assaults the Red Ribbon Headquarters in order to retrieve the remaining balls. At this moment, Red ordered Black to fight Goku himself. Goku had defeated Black in hand-to-hand combat before Red accidentally revealed his true intentions.
Discovering that Red only wanted the balls to become taller, Black is unwilling to serve Red any further and shoots his boss in the head, killing him. Black then decides he will reconstruct the Black Ribbon Army and conquer the world. Confronting GokuEdit Just then, Goku finds him and demands the balls. The newly crowned Commander Black tries to talk Goku into civil discussion so both of them could conquer the world, but Goku refuses. Black then throws a capsule, containing a robotic battle jacket, which he uses to fight Goku. Goku has a hard time fighting Black in the battle jacket but manages to get some hits. Black then shoots a nuke missile in an attempt to blow the entire HQ with Goku on it, showing that he, like Red, could care less about his soldiers. But the Saiyan kicks it back at Black, who luckily dodges the missile, which destroys a mountain in the distance. Black then attempts to escape but Goku then uses an all-out attack against him, which pierces the battle jacket, blowing it up and killing the short-lived commander in the process.
