In many Who fanfictions, Harry could potentially be the master doctor, but it really varies based on the author's imagination and the plot they've created. Sometimes the characterizations and roles can be quite unique and unexpected.
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.
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.
Hermione would probably be one of the common characters. She could be helping Harry in his research, using her vast knowledge to find solutions to difficult medical cases. Maybe she'd be working on developing new potions for healing.
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.
In this fanfiction, it's Harry, the boy wizard from the magical world of Hogwarts. And then there's the 9th Doctor, a time - traveling alien with his own set of skills and a big blue box called the TARDIS. They are the central figures around which the story would revolve.
A well-liked one is 'Time and Magic'. It weaves a tale where Harry and Hermione's presence brings a unique dynamic to the Doctor's travels, facing challenges and uncovering mysteries together.
