Assistant Black

Assistant Black is the second in command of the Red Ribbon Army.

Story
Black worked as the right-hand of Commander Red, acting as his advisor. Believing Red sought world domination, he helped him build the Red Ribbon Army and hired all of his officers, in order to search for the Dragon Balls. 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 beaten by Goku, who was also seeking the balls. After Goku defeats Mercenary Tao, who had been hired by them, he assaults the Red Ribbon Headquarters in order to retrieve the remaining balls. At this moment, Commander Red panicked, accidentally revealing to Black his true intentions. Discovering that Red only wanted the balls to become taller, Black gets furious and shots his boss on the head, killing him. Black then decides he will reconstruct the Red Ribbon Army and conquer the world. Just then, Goku finds him and demands the balls. Black tries to convince Goku to join him 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, but manages to get some hits, so Black shots a nuke missile in an attempt to blow the entire HQ with Goku on it, but Goku kicks it back at Black, who luckily dodges the missile, which destroys a mountain in the distance. Goku the uses an all-out attack against Black, which pierces the battle jacket, blowing it up and killing Black in the process.

Trivia
Black was seen again during the Super 17 saga in Dragon Ball GT, being one of the villains who escaped from hell, along with other Red Ribbon members.
