Well, Naruto's chakra-based powers and Pikachu's electric powers can combine in some fanfictions. For instance, Naruto could use his Rasengan and Pikachu could add its electric charge to it, creating a super - charged attack that is more powerful than either of their individual attacks.
Detective Pikachu is not a visual novel. It's a unique form of entertainment that combines live-action elements with Pok茅mon characters in a cinematic adventure. Unlike a visual novel, it focuses on visual and narrative experiences on the big screen.
Definitely. The idea of Ash and Pikachu's friendship is very popular in fanfiction. Their relationship is iconic. Fanfictions could tell stories of how they first met and how that initial connection grew into an unbreakable bond. It could also include side characters from the Pokémon world who notice and are inspired by their friendship, like Misty or Brock seeing how Ash and Pikachu always have each other's backs.
One possible reason could be that Ash senses a dangerous situation where Pikachu's full power might attract unwanted attention or put them in more danger. For example, if there are powerful and unseen enemies nearby, Ash might hold Pikachu back to keep a low profile.
In a fanfiction, Ash and Pikachu could enter a Pokemon contest where the theme is lemons. Pikachu has to use its skills in a creative way related to lemons. Ash trains Pikachu hard, and they come up with a unique performance where Pikachu zaps lemons to create a spectacular light show. This earns them high marks from the judges and they make new friends among the other contestants.
According to the information provided, I recommend a novel called "Pokemon of the Wood Leaf." The general plot is about the main character meeting Billy Pikachu. Pikachu turns into a zombie, and in the story, he meets Mario the zombie. I hope you like this fairy's recommendation. Muah ~😗
