The Black Bull resembles a cross between a giant maggot and a dragon. Due to its large blubbery body, its only weak spot is its single green eye. It can breathe fire and produce Black Wings from its mouth. It appears as a boss in Shadow the Hedgehog after the Lethal Highway or Death Ruins stage is completed. Shadow can either use a Homing Attack or shoot its eye in order to damage it.
- It is possible that its name is a reference to Nintendo's F-Zero series, where the main antagonist, Black Shadow, races in a machine known as the Black Bull. The same thing can be said for Blue Falcon, which is also the name of the machine Captain Falcon of the F-Zero series races. As SEGA helped develop F-Zero GX, this is not entirely unlikely.
- Despite the name, Black Bull looks nothing like an actual bull.
