The Bull is a quad-pump action shotgun, that fires energy pellets equivalent to HE shotgun pellets. It has the recoil of a bull, so it takes a couple of seconds between each shot to line the shot back up. Each of its four barrels shoots a pellet simultaneously when the trigger is pulled, and each barrel is reloaded at the same time. The Bull's barrels can each shoot four times before it needs a one post reload.
It appears in Xionic Madness 2.
