Wilhelm

Wilhelm is a Hyperion Engineer who serves Handsome Jack, and who nearly killed the original Vault Hunters after the events of Borderlands. He is one of the bosses in Borderlands 2. He has also been announced as a playable character in the upcoming game Borderlands: The Pre-Sequel! as Wilhelm The Enforcer.

Wilhelm is the first major boss of the game (Major bosses are indicated by health bars on the HUD instead of above the enemy). He is mentioned multiple times by the Guardian Angel, with considerable trepidation, before he is fought at the End of the Line.

Physically he is part Hyperion loader, with his body from the waist down replaced with loader legs. From the waist up, Wilhelm resembles an engineer with a constructor's optic sensor in the place of his right eye. Wilhelm also bears a shoulder-mounted mortar, which he uses for ranged attacks.
