Motorhead

Motorhead is a large hulking mini-boss type enemy who can be found in an off-ramp along one of the Crimson Lance controlled/patrolled highways in the Secret Armory of General Knoxx DLC of Borderlands. Motorhead can be found when the player is given a side quest by one of the seemingly non-evil midgets named Thirsty, who also happens to like purple juice found in pumps named after Lord of the Rings characters.

Motorhead boasts a shoulder-mounted minigun (complete with laser sight) and flings bombs which knock the player back causing some minor disorientation.
