From Hawk & Croc Classic #102
Doctor Baghead is the primary physician at Leonardo Hospital, often seen working with the lovely Nurse Betty. He treated Gila for superficial wounds, and has treated Hawk for both a de-attached hand and a shattered foot. He's a miracle worker who wears a paper bag over his head.
In case it isn't completely obvious, Dr. Baghead is loosely styled after Faust from the Guilty Gear video game series.
