Black Bull
Black Bull is a monstrous member of the Black Arms and a boss-level enemy in Shadow the Hedgehog summoned by Black Doom in order to burn the city to the ground as well as kill Shadow should he choose to oppose the Black Arms.

Despite its name the Black Bull is a flying one-eyed grotesque maggot-like monster with a bloated body and the ability to breathe fire while also summoning smaller enemies - intelligence-wise it can be seen as animalistic with no real intelligence of its own outside of attacking and destroying.
