Well, perhaps the story could be about Orochimaru seeing Harry as an interesting experiment. He might teach Harry things like advanced potions and how to handle dangerous magical creatures in a very unorthodox way compared to Hogwarts' teachings. But Harry would constantly be in a moral dilemma, whether to accept Orochimaru's teachings which are often on the edge of what is considered good magic in the wizarding world.
Hermione could be one of the main characters. She might be suspicious of Orochimaru's teachings and try to convince Harry that it's wrong. She would be constantly researching about Orochimaru and the type of magic he's teaching Harry to prove her point.
Well, perhaps Peter Parker teaches Harry about the value of secrecy. Since Peter has to keep his identity as Spider - Man a secret, he could pass on that wisdom to Harry. Also, he could teach Harry some acrobatic skills which are useful in combat situations. Peter might use his own life experiences to mentor Harry in making moral choices.
One possible plot could be that Naruto, as Orochimaru's son, struggles with his identity. He might have Orochimaru's scientific genius but also Naruto's determination. He could be shunned by the village at first due to Orochimaru's bad reputation. But then, he uses his unique skills to prove himself, perhaps by developing new jutsu that combines Orochimaru's snake - related techniques with Naruto's own chakra - based powers.
One possible plot could be that Naruto, feeling ostracized in Konoha due to his jinchuriki status, decides to join Orochimaru. Orochimaru, seeing Naruto's potential, trains him in some dark and forbidden jutsus. Naruto might start to change, becoming more cynical. He could use his newfound powers against those in Konoha who once shunned him, leading to a series of battles between him and his former friends like Sasuke and Sakura.
Perhaps the fanfic could be about an Orochimaru's student who is sent on a secret mission. On this mission, they meet different characters who make them question their loyalty to Orochimaru. They could also find a hidden power within themselves that is not related to Orochimaru's teachings. This new power could be the key to their redemption or a new path away from Orochimaru.
Well, it could be a really strange plot. Maybe in this fanfiction, Fem Harry Potter is intrigued by Orochimaru's dark and mysterious magic. She might see his ability to transform and experiment with different forms of life as something unique. Since she has her own experiences with magic in the wizarding world, she could be interested in exploring Orochimaru's more unorthodox methods. It could also involve her trying to understand Orochimaru's motives, perhaps thinking that there's some good in his actions deep down, which is a very different perspective from what most in the Harry Potter universe would think.
Well, one possible plot could be that Orochimaru somehow finds his way into the Harry Potter universe. He might be interested in the unique magic there, like the Elder Wand or the Philosopher's Stone. He could try to use his ninja skills and devious ways to steal these powerful magical items, and Harry and his friends would have to stop him using their own magic.
Maybe in this fanfic, Naruto has been influenced by some dark force or a traumatic event that makes him turn to Orochimaru. Orochimaru, seeing Naruto's potential, convinces him to work together. Naruto's tasks could involve helping Orochimaru in his experiments. However, as time passes, Naruto realizes the true evil nature of Orochimaru and has to struggle between the loyalty he feels due to the power he's gained and his own moral compass.
Perhaps in the fanfic, Hestia teaches Percy about the power of patience and stability. Percy is often quick to act, but Hestia could show him how waiting for the right moment and having a stable foundation can be more powerful. She might use examples from her own long existence, observing the rise and fall of civilizations. This newfound knowledge could change Percy's approach to challenges, making him not only a stronger hero but also a wiser one.
One possible plot twist could be that Orochimaru has an ulterior motive for training Sakura. Maybe he wants to use her new - found skills against Konoha in the future. Another could be that Sakura discovers a hidden power within herself during the training that Orochimaru wasn't expecting.
