The plot could involve Sephiroth being reincarnated into the body of a young wizard. He has his combat skills and a thirst for power from his previous life. At Hogwarts, he quickly rises to the top of his classes in combat - related magic. But his dark nature from his past life starts to surface. He becomes interested in the Dark Arts and begins to explore forbidden magic. The story could revolve around Harry and his friends realizing the threat Sephiroth poses and trying to prevent him from unleashing chaos in the wizarding world. Maybe there are also elements of Sephiroth trying to find a way to return to his original form or merge the two worlds together for his own gain.
Well, perhaps Sephiroth's reincarnation in the Harry Potter universe is a result of some ancient magic gone wrong. He is born with his signature long silver hair and a strange, otherworldly aura. As he grows up, he discovers his past life memories and decides to use his knowledge of both worlds to gain ultimate power. He might start by manipulating the Hogwarts houses and eventually aim to take over the entire wizarding world. He could form alliances with dark wizards and creatures, all while the main Harry Potter characters try to stop him.
Yes, there might be. The Harry Potter and Final Fantasy universes are both very popular, so it's likely that some fans have combined elements from both in fanfiction. You can try searching on fanfiction websites like Archive of Our Own or FanFiction.net.
Well, one possible plot could be that Harry discovers his true father is Sephiroth. This could lead to him having new and strange powers that he has to learn to control. He might face discrimination from both the wizarding world and those who know of Sephiroth's dark past. And he would have to figure out how to use his new identity to fight against the forces of evil in the wizarding world, which could be different from the normal threats Harry usually faces.
Well, it could be that Naruto is reborn as a sort of hybrid of himself and Sephiroth. His appearance might change slightly, with some of Sephiroth's features. In the story, he might have to learn to control the new powers which are far more destructive than his normal chakra - based abilities. And his friends, like Sasuke and Sakura, would be both confused and worried about this new Naruto.
In a 'Harry Potter reincarnation of Gilgamesh' fanfiction, the story could begin with Gilgamesh's reincarnation being born into a wizarding family. He quickly shows extraordinary magical abilities that are not typical of a normal wizard. As he grows up, he becomes aware of his past identity. He might be drawn to the Forbidden Forest, believing it to hold secrets related to his past. He could encounter magical creatures there that recognize his ancient soul. His presence in the wizarding world could disrupt the balance between good and evil as dark forces become interested in his power, while the good side tries to convince him to use his power for the right reasons.
One possible plot could be that Loki, reincarnated in the Harry Potter world, is initially confused by his new surroundings. He then discovers that his powers are still there but manifest in different ways in the wizarding world. He might get involved in the fight against Voldemort, not because he's on the side of good, but because he sees an opportunity for chaos and power. Along the way, he forms unlikely alliances with some of the Hogwarts students, who are both intrigued and wary of him. And his presence might also disrupt the normal order of the wizarding world, causing new problems and solutions to emerge.
Well, in such a fanfiction, the plot could involve Harry being hunted by both the good and the bad forces in the wizarding world. The good ones fear his Lucifer - like powers might corrupt him and the bad ones either want to use him or destroy him to prevent him from becoming too powerful. His friends, like Hermione and Ron, would be in a difficult position of trying to save Harry from himself and from those who want to harm him. There could also be a journey where Harry has to go to some dark and mysterious places to uncover the truth about his reincarnation and find a way to control or change his fate.
In 'Harry Potter Sephiroth fanfiction', a recurring theme is the adaptation of Sephiroth to the new environment. He has to deal with the rules, cultures, and social structures of the wizarding world. There may also be a theme of power struggle, as Sephiroth's power could either be a threat or an asset in the fight against the dark forces in the Harry Potter series. Additionally, the theme of identity can be explored, as Sephiroth may question who he is in this new and different world.
The plot could involve Harry gradually realizing his past life as Tobirama. He might start having strange dreams or visions. As he discovers his reincarnation, he could use Tobirama's ninja - like strategies in the wizarding world. For instance, his ability to plan and execute complex maneuvers could give him an edge against Voldemort. Also, he could introduce some of Tobirama's ideas about leadership and community building to Hogwarts, changing the way the school is run.
The plot could involve Harry realizing his connection to Madara early on. He then uses Madara's knowledge of power and leadership to change the power dynamics in the wizarding world. Maybe he starts to train his friends in a more intense, ninja - like way. He could also face opposition from the existing wizarding authorities who are threatened by his new and different approach inspired by Madara's memories.
It would be really wild. Harry would grow up with Sephiroth's strict and powerful influence. He might learn combat skills much earlier and in a very different way compared to how he was raised in the original series. His view of magic and power could be warped by Sephiroth's teachings.
