A really interesting plot development could be the connection between Loki's magic and the magic of the wizarding world. Harry could start to experiment with combining the two types of magic. For example, she might use Loki's magic of deception to create false horcruxes to mislead Voldemort. This could lead to a complex web of intrigue as Voldemort tries to figure out which are the real horcruxes and which are the fakes. At the same time, Harry could be exploring her relationship with her father through memories or encounters with Loki's essence, which would add a whole new emotional and character - driven aspect to the story.
Perhaps the main plot could be about her search for a sense of identity. She doesn't fully belong in either the world of the Norse gods or the Harry Potter wizarding world. She has to navigate through different cultures, magic systems, and social norms. Along the way, she meets various characters who help or hinder her in this quest for self - discovery.
It would change the whole backstory of Harry. Instead of being an orphaned wizard with a connection to Voldemort, she'd have a connection to Loki. This would mean different motives and goals. Her character arc might not be about defeating Voldemort but rather about understanding her place in both the wizarding world and the Norse mythological world.
Perhaps she is a seeker of some sort of ancient artifact that has significance in both the Bleach and Harry Potter lore. This could lead her to interact with different houses at Hogwarts, each with their own motives regarding the artifact. Some might want to use it for power, while others want to keep it safe. Her journey would involve not only finding the artifact but also dealing with the politics and rivalries within the wizarding school.
Well, perhaps Harry could use his magic skills like the Patronus charm to hold Loki at bay. Since Harry has experience dealing with dark forces, he might be able to outwit Loki's trickery.
Well, perhaps Harry Potter, in the guise of Loki, uses his trickery skills in the wizarding legal system. He could be defending those wrongly accused of using dark magic, like using his shape - shifting abilities to find evidence that others can't.
One possible plot could be that Harry starts to show Loki - like traits early on at Hogwarts. He might use his trickery to outwit his enemies, like the Malfoys. Maybe he even uses some of Loki's shape - shifting abilities in a magical way to get out of tricky situations during his adventures.
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.
The plot could start with a dark spell or some kind of mind - altering event that turns Harry into the Joker - like figure. Then, he might start attacking the very people he once protected, like his classmates at Hogwarts. This would create a lot of chaos within the school walls. The teachers would be at a loss on how to deal with him, as his magic combined with the Joker's unpredictable nature would be a very difficult combination to handle.
The plot could start with Harry escaping the Dursleys earlier than in the original. He then roams around, trying to find a place to belong. He might stumble upon some hidden magical secrets in the Muggle world that are related to his parents. As he grows, he starts to attract the attention of both good and bad wizards. Some might want to help him, while others see him as a threat because he's an unknown factor, not following the normal wizard upbringing.
The plot could start with Harry's birth into the Weasley family. He'd grow up with the Weasley values and traditions. As he gets older, he might discover his true identity in a different way. Maybe he'd find out he has some special connection to Voldemort that's not related to his parents' death. His relationships with the other Weasley siblings would be key. For example, his bond with Percy could be different, as they'd be brothers from the start. And he'd have a different role in the fight against Voldemort, perhaps leading the Weasley family in the battle more directly.
