Well, obviously Naruto himself would be the main character. There could also be his friends like Sasuke and Sakura, who might be involved in the interactions between the two Narutos. Maybe they are confused at first by seeing two Narutos, but then they help them figure out what's going on.
In addition to Naruto, the Nine - Tailed Fox could be a significant character in this fanfic. Since the Nine - Tailed Fox is an important part of Naruto, when the two Narutos meet, the Nine - Tailed Fox might have different reactions in each of them. It could create some interesting conflicts or cooperation between the two Narutos.
Obviously, Naruto and Jiraiya are the main characters. They are the focus of the 'naruto meets jiraiya' concept. Naruto, the energetic and determined ninja, and Jiraiya, the wise and powerful mentor.
Obviously Naruto and the Sage of Six Paths. Naruto is the main protagonist of the Naruto series, so it's natural for him to be a main character in this fanfic. And the Sage of Six Paths is a very important figure, so his presence is crucial.
Obviously, Naruto and Jiraiya would be the main characters. Naruto, the protagonist of the original series, and Jiraiya, his mentor. They have a deep connection, and any fanfiction about them meeting would revolve around their relationship.
Obviously, Naruto would be one of the main characters. He's the central figure from the Naruto universe. And then there would be the Pokegirl. She could be any type of Pokegirl, like a Pikachu - girl or a Charmander - girl. Their different personalities and abilities would drive the story forward.
Naruto and Aang would be the most obvious ones. They are the main characters in their respective worlds.
Obviously, Naruto and Jiraiya are going to be the main characters. Naruto, the young and energetic ninja - in - training, and Jiraiya, the experienced and somewhat eccentric sage. There might also be some side characters like the villagers of Konoha who could react to Naruto's new relationship with Jiraiya.
In 'Naruto meets the tailed beasts fanfiction', Naruto is surely a main character. As for the tailed beasts, they are like co - protagonists. Naruto's relationship with each tailed beast, such as Kurama, will be explored. And there might also be other supporting characters from the Naruto universe, like Kakashi or Sakura, who could react to Naruto's new interactions with the tailed beasts.
The main characters are likely to be Kurama and a bunch of unnamed kids at first. But as the story unfolds, we might find out more about these kids. They could be orphans with special powers that only Kurama can understand or help develop. Maybe one of the kids has a natural affinity for the nine - tailed fox's chakra. There could also be a kid who is initially very skeptical of Kurama but later becomes his biggest supporter. And of course, Kurama himself, with his vast power and complex personality, will be central to the interactions with the kids.
It could still be Naruto himself. Since he's the central character in the original series, many fanfics would likely continue to build on his story.
Sasuke would be a likely character to interact. Given their complex relationship throughout the Naruto series, Sasuke might be suspicious or intrigued by Naruto's control over Zetsu. Their interactions could range from confrontations to reluctant teamwork.
