In the 'kabuto sad story', Kabuto could be anyone really. He could be a character from a small - town folktale, where he was known for his kindness but was wronged by the people in the town. Maybe he was framed for a crime he didn't commit, and as a result, he lost his reputation and had to live in isolation. This would be a very sad situation for him indeed.
To develop Fem Kabuto's character, give her a personal goal that is separate from Orochimaru's. In the fanfiction, she might strive to find a cure for a certain ninja - world disease using her medical knowledge. This not only shows her as more than just a sidekick to Orochimaru but also gives her a positive and independent identity. As she pursues this goal, she can grow and change, and her interactions with Naruto can be shaped by this new - found purpose.
Naruto could be a great addition. His friendship with Sakura and his complex relationship with Kabuto in the original series could add an interesting dynamic. For example, Naruto might suspect something is going on between Sakura and Kabuto and try to interfere or understand what's happening.
I'm not sure specifically what the 'kabuto sad story' is without more context. It could be about a person named Kabuto who faced some sort of misfortune, like losing a loved one, or perhaps it's related to a character named Kabuto in a particular story where something sad happened to him, such as being betrayed by friends or failing in an important mission.
The concept is cool because Kabuto has a lot of unique abilities. If Harry has those abilities, it can change the power dynamics in the Harry Potter story. For instance, his medical ninjutsu could be used to heal the injured in the wizarding wars in a different way than normal magic. It also adds an element of mystery as the other characters try to figure out how Harry got these new powers.
One common theme is redemption. Given Kabuto's complex past, many fanfictions explore his journey towards redemption with Sakura often playing a role in that. For example, she might be the one to show him a different path.
In fanfics, Orochimaru and Kabuto often have a complex relationship. Orochimaru is a powerful and somewhat villainous character. He sees potential in Kabuto and takes him under his wing. Kabuto, on the other hand, is initially in awe of Orochimaru's power and knowledge. Their relationship can be seen as a mentor - apprentice dynamic at first, with Orochimaru guiding Kabuto in the ways of ninjutsu and his own brand of experimentation. However, as Kabuto grows, he begins to develop his own identity and goals, which may sometimes conflict with Orochimaru's plans.
Orochimaru is a significant character in fanfic as he represents a powerful and morally ambiguous figure. His presence adds a sense of danger and mystery. Kabuto, on the other hand, is often portrayed as a complex character. His loyalty to Orochimaru and his own personal growth are key aspects. In fanfic, Orochimaru's actions can drive the plot forward, especially his experiments and his pursuit of power. Kabuto's role is often to support Orochimaru initially, but as he develops, he can become a key player in his own right, with his own motives and goals.
One great 'Harry is Kabuto' fanfiction could be one where Harry uses Kabuto's skills in the wizarding world. For example, his knowledge of herbs and potions in the Naruto world, as represented by Kabuto, could help him create new and powerful potions in Hogwarts.
If Naruto is trained by Kabuto in fanfiction, it could lead to a very different Naruto. Kabuto has a vast knowledge of various jutsu and forbidden techniques. Naruto may be exposed to a darker side of the ninja world through this training. He might develop a more cynical view, but on the plus side, he could also become a more versatile fighter with new jutsu at his disposal.
