In most Doctor Who and Naruto crossover fanfictions, this isn't a common plotline. So, it's highly unlikely.
The idea of the 10th Doctor being Naruto's dad is a very unique and uncommon concept in fanfiction. It's not a typical or mainstream idea that you'd come across often.
The 10th Doctor in the Naruto universe could be a real game-changer. His advanced technology and unique perspective could shake things up. However, he'd face challenges like dealing with powerful jutsu and understanding the complex social structure of the ninja villages.
The 10th Doctor's compassion and curiosity could have a profound impact on Naruto's development. Maybe he'd introduce Naruto to new worlds and concepts, expanding his horizons.
Well, it varies in different fanfics. The 11th Doctor could be hurt by powerful villains, or maybe in trying to save someone. It could also be from internal conflicts or emotional stress.
It could be due to various imaginative plot devices created by the fanfiction author. Maybe in a battle with a powerful villain or during a risky adventure.
At first, Naruto might be a bit wary of the strange Doctor. But as the Doctor starts to show his kindness and knowledge, Naruto would grow to respect and trust him. The Doctor, on the other hand, would see Naruto's potential and determination, and would be like a father figure to him. They'd have a relationship based on mutual learning, with Naruto learning about the Doctor's world and the Doctor learning about the ninja way.
It could be the Daleks. They are a classic Doctor Who villain. They might see the meeting of two Doctors as a threat to their plans for universal domination and try to stop it.
I can recommend 'The Time Healed Wounds' - it's a great one where they comfort each other after a particularly tough adventure.
Yes, in many fanfictions, Clara has deep feelings for the 12th Doctor.
The story could involve the OC having a special ability or background that complements or contrasts with the 10th Doctor. Maybe it brings a fresh perspective to familiar Doctor Who themes.
In many fanfictions, the 13th Doctor might get hurt during intense battles with villains or in risky time-travel adventures.
