Well, it could show Orochimaru as a secret admirer of the Harry Potter series. He could be collecting items related to it in his lair in the Naruto world. Then, through some magical mishap, he gets transported to the wizarding world. Once there, he'd be like a fish out of water but quickly adapt. He'd start exploring the different spells and potions, comparing them to his own jutsu. He might also try to find a way to bring some of the powerful magic back to his own world, all while causing chaos and confusion among the Hogwarts students and faculty.
In a fanfic about Orochimaru being a Harry Potter fan, he might be obsessed with the idea of immortality in the Potterverse. He could have read about the Philosopher's Stone and be determined to get his hands on it. He'd use his ninja skills to spy on the characters in the wizarding world. He could also attempt to create his own version of Hogwarts in the Naruto world, recruiting young ninjas and teaching them a mix of ninja techniques and Harry Potter - inspired magic. The fanfic could explore his reactions to the different magical creatures and how he'd try to incorporate them into his own plans for power and domination.
It might have Harry Potter secretly collecting Sailor Moon merchandise in her dorm at Hogwarts. She could be seen comparing the magic in her world to that of Sailor Moon. For example, how the spells in Harry Potter are different from Sailor Moon's attacks.
It would be a very interesting and unique crossover. Harry Potter's magical world with its spells, wands, and Hogwarts could blend oddly with the Akatsuki's world of ninjas, their unique powers and their mysterious goals. For example, Harry could use his magic to counter some of the Akatsuki's jutsu. Or perhaps a member of the Akatsuki might be interested in the power of the Philosopher's Stone.
Well, it might look like Hogwarts being placed in Westeros. The houses in Hogwarts could interact with the different houses in Game of Thrones. Gryffindors could team up with the Starks, known for their honor. Slytherins might find common ground with the Lannisters, being cunning and power - hungry. And the magic of Harry Potter could be used to change the fates of the characters in Game of Thrones. Maybe Hermione could use her intelligence to outwit Littlefinger, or Ron could befriend some of the knights in Westeros.
Well, it could be really wild. Maybe Harry, through some time - travel mishap, ends up in a world where he has the essence or some of the powers of Orochimaru. He might be able to use snake - like abilities, like Orochimaru can in Naruto. And the story could be about him trying to figure out how to get back to his own world while dealing with these new and strange powers.
There's no evidence in the official Naruto or Harry Potter works that Orochimaru is a Harry Potter fanfic. But fanfiction is all about creativity and bending the rules. If someone were to write such a fanfic, Orochimaru could be written as a character who has somehow discovered the Harry Potter books or movies in his world. He could be envious of the power of the wizards, or he could see opportunities to learn new forms of magic. It would be a very unique take on both franchises, but again, this is all in the world of fan - created content.
The storyline could be very dark. Naruto, as Orochimaru's apprentice, might be forced to learn some forbidden jutsu. He would probably be in a constant moral struggle. Orochimaru is known for his unethical experiments, and Naruto could be made to assist in them. However, Naruto's inherent goodness might lead him to try and subvert Orochimaru's plans from the inside. Maybe he would pretend to go along with Orochimaru's ideas while secretly finding ways to undermine his power and free the other captives in Orochimaru's lair.
Well, it could be really exciting. They could combine their magical powers. Percy with his water - controlling abilities and Harry with his wizardry. Maybe they'd fight together against common enemies, like some dark forces that threaten both the wizarding world and the world of Greek gods. They could also learn from each other's cultures. Percy could show Harry the wonders of the Greek pantheon and Harry could introduce Percy to the magic of Hogwarts.
In a fanfic crossover, it could start with a strange magical accident that pulls Tony Stark into the Hogwarts grounds. The students are amazed by his Iron Man suit, and Harry Potter is tasked with keeping an eye on this strange Muggle. As they interact, Stark starts to figure out the rules of magic, and Harry starts to see the potential of Muggle technology in the fight against dark wizards.
Well, it could start with Hermione being in a vulnerable situation, like being cornered by the troll in a dark, damp dungeon. Harry, being the brave hero, arrives just in time. He might first distract the troll by conjuring up some annoying little creatures that the troll would start chasing. Then, when the troll's back is turned, Harry would grab Hermione and apparate them both to a safer place, like the Gryffindor common room.
His personality would be a mix of his original self and Orochimaru's influence. Harry is inherently brave, but Orochimaru's devious nature might make him more cautious and calculating. He might be less trusting of others, always suspecting ulterior motives. And he could also be more ruthless when it comes to achieving his goals, having learned from Orochimaru that sometimes you have to be cruel to get what you want.
