Definitely Marvel. Thor has been a key figure in Marvel comics for a long time. His adventures and storylines are all part of the Marvel comic universe's rich tapestry.
I'm not sure if there is such a specific fanfiction. But if it exists, it might be a really wild crossover. Maybe Naruto somehow gets the powers of Thor from DC and has to use them in the Naruto universe. For example, he could use Mjolnir instead of his kunai and shuriken, and his Rasengan could be infused with lightning like Thor's powers.
A common theme is the clash of different power systems. Thor's godly powers from Asgard are very different from the powers of DC heroes. Fanfics often explore how these powers interact, like Thor's lightning against Superman's heat vision.
It really depends on personal preference. DC often has darker and more brooding storylines, with iconic characters like Batman. Marvel, on the other hand, is known for its more relatable and humorous heroes like Spider - Man. In the graphic novels, DC might appeal to those who like complex, multi - layered stories, while Marvel could be great for fans of action - packed, fun - filled adventures.
The number of DC vs Marvel comics is quite variable. It depends on various factors like publication schedules and crossovers. However, it's safe to say there are dozens, if not hundreds.
It's hard to give an exact number as new comics are constantly being produced. But there are a significant amount, probably in the hundreds or even thousands.
One major difference is the tone. DC tends to be darker. For example, Batman's stories are often set in a gritty Gotham City. Marvel is generally more light - hearted, like the adventures of the Fantastic Four. Another difference is the character archetypes. DC has a lot of super - powerful, almost god - like characters. Marvel has more characters who are normal people with extraordinary abilities.
