dr who the 13th doctor

I'm not exactly sure, but you might be able to find the accurate number on dedicated Dr Who comic fan sites or forums.

Well, you might find a plot where the 10th Doctor teams up with characters from different timelines to save a collapsing reality. Another interesting one could be him facing an ancient evil that was thought to be long gone.

The Daleks could be the main villain. They might be trying to manipulate the Doctor's regeneration to create chaos in the time - space continuum. Since the 9th Doctor's unexpected jump to the 11th Doctor disrupts the normal flow, the Daleks could take advantage of this instability to further their evil plans of universal domination.

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.

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.

Sure. Although the 8th Doctor has a long and complex history in the novels, new fans can still jump in. For example, some novels start with a self - contained story that gives a good overview of who the Doctor is and what he does. They gradually introduce the lore and concepts associated with him, so new fans won't feel too lost.

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 most Doctor Who and Naruto crossover fanfictions, this isn't a common plotline. So, it's highly unlikely.
