The main characters would be Naruto for sure. Among the Eevees, there might be an Eevee with a leadership quality. This Eevee could be the one that initially decides whether Naruto can stay or not. There could also be a young Eevee that Naruto takes under his wing and teaches things to, which would also be an important character in the story.
Obviously Naruto is one of the main characters. And then, there would be the Eevees. There could be a special Eevee that stands out, like an Eevee that is more curious about Naruto than the others and becomes his closest companion among the Eevees.
Naruto is the key human character. As for the Eevees, there could be a mischievous Eevee that always gets into trouble and Naruto has to rescue it. There may also be an Eevee that has some special powers among the group, and Naruto and this Eevee work together to protect the Eevee community from any potential danger.
Well, perhaps Naruto is sent to a dimension where Eevees are the main inhabitants. He has to adapt to living with them. He could form strong bonds with individual Eevees, like an Eevee that's really brave and they go on adventures together, exploring the new land and facing challenges that are unique to this world of Eevees.
Obviously Naruto would be one of the main characters interacting with him. Naruto would look up to Sarutobi as a mentor and a source of knowledge. Their interactions could range from training sessions to deep conversations about the future of the village.
Sakura would probably be a side character. She could be the one who checks on Hinata's health during her pregnancy if that's part of the story. Shikamaru might also be there, helping Naruto with some of the strategic planning for the village while also giving him relationship advice. And Boruto and Himawari would be important side characters as their children, adding a family - centered aspect to the fanfiction.
Obviously Naruto would be one of the main characters. He's the protagonist of the original series and his power and will would be crucial in a doomsday scenario. Sasuke would also be likely, as his strength and his connection to Naruto are important elements. Sakura, with her medical skills, would also be a key character as she could be responsible for healing the injured during the doomsday chaos.
Well, it's possible that some new or less - known characters from the Naruto universe could become main characters in 'chaos naruto fanfiction'. For example, Rock Lee could take on a more central role. He has always been a character full of determination and unique fighting style. In a chaotic setting, his strong will could be a key factor in dealing with the chaos. And then there are the jinchuriki of the other tailed beasts who might be more prominently featured as they are all related to the power dynamics in the Naruto world which could be thrown into chaos.
Obviously, Naruto would be one of the main characters. Since it's a Naruto - centered fanfiction with the beyonder element added. Sasuke could also be a main character as he is often Naruto's counterpart and rival. They might both be involved in exploring the beyonder powers. Additionally, characters like Kakashi could play important roles. He could be the one guiding Naruto and Sasuke in understanding these new and strange beyonder powers, given his experience and wisdom.
There may be new characters introduced as well. Maybe a mysterious figure who has a special ability to either enhance or dampen Naruto's will to live. This character could add an extra layer of mystery and conflict to the fanfiction.
Naruto would be the central figure. But in this British version, there could be new characters added, like a British wizard - type character who becomes Naruto's mentor in understanding the new 'British - ninja' aspects of his life. And of course, Sasuke and Sakura would be adapted to fit the British setting, perhaps with different family backgrounds that are more in line with British culture.
Definitely Naruto himself. He'd be a central character, causing chaos and bringing energy to the daycare. And Sasuke would also be there, probably being a bit of an aloof kid that Naruto is determined to get close to.
I think Kakashi would be an important character too. He could be Naruto's mentor in this new situation, teaching him how to use his remaining abilities effectively. Also, Sakura might be there, using her medical ninjutsu skills to try and help Naruto with his crippled state.
