Obviously, Naruto would be one of the main characters. And there could be a Pokémon trainer who raises him. Maybe someone like Ash from the Pokémon series could make an appearance as a mentor - like figure to Naruto. Also, Naruto's friends in the ninja world could interact with the Pokémon, so they could also be important characters in this fanfiction.
There might also be other Pokémon that interact with Ash and Lucario in the fanfiction. They could be friends, rivals, or just part of the Pokémon world that Ash and Lucario encounter during their adventures. However, Ash and Lucario are the central focus of this particular fanfiction.
Obviously, Naruto is one of the main characters. And then there would be the cats that raise him. They could be a group of cats with different personalities, like a wise old cat that imparts wisdom to Naruto, and a young, energetic cat that keeps Naruto active and playful.
Obviously, Naruto would be one of the main characters. And then there would be the elves who raise him. They could be original elf characters created specifically for this fanfiction or could be based on existing elf concepts from other works.
The plot could involve Naruto being raised in a region full of Pokémon. He may grow up learning about different Pokémon types and their abilities. This knowledge could influence his ninja training. For instance, he might incorporate the speed of a certain Pokémon into his own movement techniques. And he could also use Pokémon to communicate over long distances in a unique way, like using a psychic - type Pokémon's powers. His upbringing by Pokémon - loving people could also shape his personality, making him more empathetic towards all living beings, just like how Pokémon trainers care for their Pokémon.
The main characters would surely be Ash and Mewtwo. But there could also be other Pokemon that play important roles. For example, Pikachu might have a different relationship with Ash since Ash was raised by Mewtwo. And perhaps some of Mewtwo's clones could also be involved, adding more depth to the story.
Obviously, Naruto and Alduin would be the main characters. Naruto is the one being raised, so his growth and development under Alduin's influence would be central. Alduin, on the other hand, is the one doing the raising. His motives, his power, and his relationship with Naruto would be key aspects of the story.
It could also include other jinchuuriki from the Naruto universe. For instance, Killer Bee might be a part of it. He has his own unique relationship with his tailed beast and his inclusion could add more depth to the story. Maybe the story focuses on how these three jinchuuriki, Naruto, Gaara, and Killer Bee, interact and support each other while being raised together.
Naruto and Sheogorath are the two most likely main characters. But there could also be appearances from some of Naruto's original friends like Sasuke and Sakura, though their relationships with Naruto would be very different. They might be more like outsiders looking in on Naruto's strange new life under Sheogorath's influence. Also, characters from the Sheogorath's world might make an appearance in the fanfiction, further complicating Naruto's life and the overall story.
In this fanfiction, there might be a Kiri - native ninja who discovers Naruto when he's just a child and takes him in. This character would be an important one, as they would be the one to introduce Naruto to the ways of Kiri. Also, there could be a group of anti - Naruto shinobi in Kiri who see him as a threat to the village's traditions and try to drive him out. They would be antagonists in the story.
Obviously Naruto would be one of the main characters since he is the guardian. And there would probably be some Pokémon characters like Pikachu or Charizard that he interacts with.
