Super Doc is the only doctor in town/on the starship/in the expedition. He may have a canon field of expertise, but when called on, he can treat ANYTHING. Often in sci-fi settings, he has no nurses or other doctors to help him, sometimes with quite limited resources, and must sometimes learn and treat an alien's anatomy after about five minutes looking at it, or diagnose weird new illnesses at the drop of a hat. Even against all these odds, he usually has a high success rate. After all, he's Super Doc! Examples
