Staff Officer Black (ブラック参謀 Burakku Sanbō) is an assistant of Commander Red, and is not given much of a role until the near end of the Commander Red Saga. Black carries out Commander Red’s orders and informs Commander Red of the current situations with the remaining Red Ribbon Army officers until late in the story where he becomes Commander Black upon killing Red and usurping his position.
Staff Officer Black is a tall, dark skinned man. He is bald, has black eyebrows, and large red lips giving him an appearance similar to blackface. He is seen wearing teal slacks with black pinstripes, a white, long-sleeved dress shirt with black armbands and the Red Ribbon Army insignia on the sleeves, black dress shoes, and a black tie. He also wears a long-sleeved black suit jacket over his shirt, which has a red ribbon pinned to it.
