The Compatible Kaiser is predominantly red and gold in color. The letters BF (which stands for Battle Force, the name of the Hero team in The Great Battle IV) are inscribed on both its chest and forehead. In its original appearance, it was composed of four smaller vehicles, which combined to make the completed robot. In Original Generations, it is redesigned by Masami Obari, given a more dynamic appearance, akin to the Dynamic General Guardian series of super robots. Its main body is emblazoned in crimson, while highlights of white and blue jewels cover its arms and legs, with gold protusions appearing on its shoulders and feet.
