It's hard to say precisely. It could be that in this fanfiction, the author has found some sort of connection between Harry Potter and Solf J Kimblee. Maybe it's a crossover where the magic of Harry Potter's world interacts with the alchemical and somewhat morally ambiguous character of Kimblee. However, without reading it, it's just speculation.
The 'naruto reincarnation of solf j kimblee fanfiction' might deal with the idea of a soul transfer or reincarnation. If it's set in the Naruto world, Kimblee could be reincarnated with some of his previous life memories. This could lead to him having an edge in the ninja world, using his knowledge from his past life. He might also struggle to adapt to the new culture and abilities in the Naruto world, creating an interesting plot full of conflict and growth.
Since it's a fanfiction about Naruto being reincarnated as Solf J Kimblee, Naruto (in the form of Kimblee) would likely be a main character. There might also be other Naruto characters like Sasuke or Sakura who interact with this reincarnated form. And depending on how the story is written, characters from Kimblee's original world (if any are brought in) could also be main characters.
Searching for this specific 'harry potter is solf j kimblee fanfiction' online might be a challenge. Fanfiction communities are huge and unregulated in a sense. While some popular fanfictions are easy to come across, more niche or unusual ones like this might not be readily available. You could start by using specific keywords in the search bars of popular fanfiction platforms. If it's a relatively new or not very well - known piece, it might take a lot of digging through different categories and tags to find it, if it exists at all.
Some characters might be quite shocked or amused if they could read fanfiction about their own story. For example, Edward Elric would probably be very indignant at some of the out - of - character portrayals of himself. He's a proud alchemist and seeing himself depicted in a way that doesn't match his self - image would surely make him fume.
Yes, it is. The manga has a perfect balance of action, drama, and philosophy. The themes explored are profound, and the character growth is very satisfying.
There probably are. Fanfiction writers often love to mash up different universes. In such a fanfic, Naruto could bring his chakra - based powers and blend them with the principles of alchemy from Fullmetal Alchemist. Maybe he'd use his Rasengan in a new way by incorporating alchemical transmutation circles. It would be a wild and creative concept.
