Super Doc

""Limited facility presents challenge...save greatest number of people using limited resources! Security threats...gangs...mercenary groups add additional difficulty, quite enjoyable! Plague stretched abilities to limit...couldn't have asked for more! Also enjoy saving people of course...helping the helpless...greater good...all that too.""

- Professor Mordin Solus, Mass Effect 2

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!

Live Action TV

Literature
""If it takes an Igor to bring you back, you were dead. Briefly dead, it's true, which is why the murderer will be briefly hanged.""
 * Discworld series:
 * Dr "Mossy" Lawn from Night Watch. And since he's the only good doctor around, he seems to go without sleep.
 * Slightly subverted in the earlier Feet of Clay; due to a lack of any competent (or trustworthy) doctors in the city, the poisoned Patrician has to rely on horse doctor "Doughnut" Jimmy. When the mob owns most of the racehorses around, a vet has to get results.
 * In Unseen Academicals, the surgical skills of The Igors is such that there is a law in Ankh-Morpork that says:


 * Madame Pomfrey from the Harry Potter series, although having access to magical remedies does help a lot.
 * And her training is clearly meant to treat more minor (relatively) injuries. More serious cases get sent to a fully qualified hospital.
 * Aes Sedai in The Wheel of Time series have the magical means to heal almost anything short of a missing limb or death, but Nynaev has an innate medical mastery that far outstrips even those who have studied the art for decades. Early on she uses healing magic that is far more effective, though proportionately difficult, than that considered standard by the Aes Sedai (because it provides the energy for the healing rather than drawing it from the patient themselves) and eventually goes on to cure conditions such as the severing of one's ability to do magic and the madness brought on by a tainted source of magic, acts considered impossible even in the nigh-omniscient AgeOfLegends.
 * James Nichols in the Sixteen Thirty Two series, but then again, he's a doctor of 2000 in the 17th century.

 * The Dragon Doctors is supposed to be what happens when you have a team of different (magically-powered) doctors banding together. None of them are good at everything, but even alone, they're each capable of amazing feats of healing.
 * A more literal "Super" Doc would be Doctor McNinja, who not only specializes in bizarre medical problems (like a disease that turns people into Paul Bunyans), but also fights crime and saves the world in his spare time.

Western Animation

 * Dr. Hibbert from The Simpsons is both a GP and a surgeon.

Video Games

 * Mordin-f**king-Solus from Mass Effect 2. Cures a bio-engineered plague in a mob-controlled Wretched Hive while three factions of gangs battle it out and try to gun their way inside his clinic just for the spite of it. Later goes on to become a chief medical officer aboard the Normandy, helping Commander Shepard save the galaxy, rarely breaking any composure.
 * Dr. Chakwas. Despite being an old woman, and the fact that humanity has only had thirty or so years' experience dealing with alien species, she knows how to treat just about any wound on any sort of species. Liara T'Soni (a 106-year-old asari scientist) is impressed at how much she knows about her species' physiology. She later proves how unflappable and determined she is by surviving the destruction of the original Normandy, leaving the Alliance just to serve aboard the illegally-constructed second Normandy, and pulling herself together after being abducted and almost liquified by the Collectors. She flat out tells you that she'll go through any sort of hell to serve at your side. How's that for Undying Loyalty?

 * The Medic from Team Fortress 2 has his medigun that can keep a fellow team member alive under heavy bullet rain at such a degree they'll die only via concentrated effort from the opposing team.

Real Life

 * Veterinarians. While some of them specialize in certain species (for example, horses), many are trained to treat numerous different forms of life.
