The mechanic has unprinted sand yellow legs and hips. The rest of his body, however, is flesh colour, as the mechanic is depicted shirtless. His torso has realistic muscle printing, with six abdominal muscles in the center and even the small muscles on each side, just below the pectorals. The German mechanic is bald and has brown eyebrows and a thick mustache. His right eye is squinting slightly with crow's feet wrinkles and there is a crease between his eyebrows in a slight frown.
The mechanic, burly as he was, easily outmatched Jones, although he unintentionally saved the archaeologist's life at one point; when the Flying Wing's pilot was about to shoot Jones, the mechanic unknowingly stepped in between Jones and the pilot, so the pilot held his fire. As he gained the upper hand of the fight, the mechanic ordered Jones to fight back, unaware that the rotating plane was drawing the propellers closer to him. Bemused when Jones ducked for safety, the mechanic turned just in time to see why before he was caught in the blades and met his end.
