I'm not sure if there is such a specific fanfiction. There are countless Naruto fanfictions out there, and while the idea of Naruto being Kimimaro's brother is quite an interesting and unusual concept, it might not be a common one. You could try searching on major fanfiction websites like Fanfiction.net or Archive of Our Own to see if it exists.
I'm not entirely sure as the statement is rather unclear. It could potentially be about a fan - made story where Kimimaro, a character from Naruto, serves in some capacity within the narrative of the fanfiction. Maybe he serves a particular character, or serves a cause within the made - up story.
One possible scenario in this fanfiction could be that Naruto discovers Haku and Kimimaro in a dire situation. Haku, with his ice techniques, and Kimimaro, with his powerful bone abilities, are perhaps being overpowered. Naruto, being the hero he is, jumps into the fray. He may convince them to change their ways and join him in Konoha, as he once did with Sasuke. This would not only show Naruto's growth as a ninja but also his ability to bring out the best in others.
Kakashi can be a popular character too. His wisdom and combat skills can be useful in fanfic scenarios involving Kaguya. He could be a mentor figure to Naruto, guiding him in dealing with Kaguya - related threats or helping to decipher ancient ninja knowledge related to Kaguya.
Yes, there are likely some fanfictions that explore a special connection between Naruto and Kaguya. In some fanfictions, authors might create scenarios where Naruto, due to his unique abilities and kind - hearted nature, manages to reach out to Kaguya in a way others couldn't. This could involve him understanding her past and trying to bring some form of redemption or peace to her.
In the fanfiction, Naruto could enter Kaguya's mind. He might discover her past traumas that led her to become so power - hungry and vengeful. By understanding her pain, Naruto could offer her forgiveness and a new path. He could show her a vision of a future where she is part of a united world, not feared or hated, but respected and loved if she changes her ways. This could be a powerful incentive for Kaguya to change.
Well, Naruto could change Kaguya in the fanfiction by introducing her to the concept of redemption. Given his own journey of facing his inner demons and coming out stronger, he might convince Kaguya that she can atone for her past sins. He may take her on a journey through the ninja world, showing her how people have rebuilt and thrived despite the chaos she once caused. This could make her re - evaluate her actions and change her perspective on the world and her place in it.
One common theme is the exploration of loyalty. Sai has his loyalty to Konoha, while Kimimaro was extremely loyal to Orochimaru. Fanfics often play with how these loyalties interact when the two characters cross paths.
Another theme can be redemption. Kimimaro was a character with a troubled past. In some fanfics, his journey with Naruto and Sai can be about finding a new purpose and redeeming himself. It's about breaking free from his previous loyalties and forging a new path with his newfound comrades.
In some fanfictions, Kimimaro survives his illness and later crosses paths with Naruto during a major ninja tournament. They end up competing against each other in the tournament. Kimimaro shows off his new - found control over his abilities and Naruto uses his latest jutsu, leading to an intense and exciting battle.
