An automated 4-legged, non-anthropomorphic robot bull animatronic without a given name or identity, and was made and programmed to act like a normal bull that's used in bullfights.

However, the robot bull animatronic starts to malfunction and goes on a fiery rampage, attacking civilians until he's taken down by animal control, who used a stun stick that shocked his power core, short-circuiting him. His malfunction caused him to self-destruct, shutting him down permanently.

Though his physical body was repaired, his internal circuitry, wiring, and power core were badly damaged. All that's left is the lifeless form of a broken-down mechanical bull. He was left in a colosseum's storage room, where he remained inactive and covered in a plastic tarp.
