It's hard to say. Harry has magic, which is a very powerful force within the wizarding world. But the Doctor has his time - traveling TARDIS and a vast knowledge of the universe. If it's a battle of raw power in a magical sense, Harry might have the upper hand. But if it's about outsmarting an enemy or finding solutions across different dimensions, the Doctor would be very strong.
Maybe it's a half - blood wizard who has studied Muggle medicine as well as wizarding medicine. This doctor would have a unique perspective and could use a combination of both types of medical knowledge to treat Harry. They might introduce some Muggle - like medical equipment into the wizarding world, which would be quite interesting. For example, they could use a stethoscope to listen to the magical 'heartbeat' of a wizard, which is different from a Muggle's. And they might also have a different approach to treating diseases, not just relying on potions but also some physical therapies.
The doctor could also be a Muggle - born wizard who has combined Muggle medical knowledge with magic. This kind of doctor would approach Harry's situation from a different angle. They might use Muggle - like scans enhanced with magic to look for internal problems. They could offer a fresh view on how magic interacts with the body, which could be very helpful in diagnosing and treating whatever is wrong with Harry.
Yes, there are likely to be fanfictions with such a concept. Fanfiction writers often like to cross over different popular universes like 'Harry Potter' and 'Doctor Who'. They might create scenarios where Harry Potter somehow takes on the role or characteristics of the Doctor.
Yes, there might be. The Harry Potter and Doctor Fate universes are both rich in magic and mysticism, so it's not surprising that some fans might be inspired to create a crossover fanfiction where Harry Potter is a fan of Doctor Fate or has some sort of connection to the Doctor Fate mythology. However, I'm not sure how common or well - known such a fanfiction is.
There could also be some characters from the Doctor's universe who oppose the idea of a half - wizard, half - Time Lord. They might come to the wizarding world to try and stop Harry from using his combined powers, fearing it could disrupt the balance between the two universes.
Hermione Granger and the Doctor are also often paired. Hermione's thirst for knowledge would be well - matched with the Doctor's vast knowledge of the universe. They could have long discussions about different forms of magic and science, and perhaps even collaborate on some sort of project that combines both.
