The magic in Harry Potter is more about spells and incantations, while Hope's magic has a more primal and ancestral feel. In a fanfiction, they could complement each other. For example, Harry's Patronus charm could be enhanced by Hope's connection to the spirit world. Or Hope's ability to draw power from the elements could be combined with Harry's knowledge of transfiguration to create new forms of magic.
It could be a dark wizard who has somehow learned about the existence of the Mikaelsons and wants to use their power to take over the wizarding world. He might be jealous of their unique abilities and see them as a means to gain ultimate power, so he targets Hope, and Harry has to protect her and stop this dark wizard.
One idea could be that Hope, with her unique powers as a Mikaelson, visits Hogwarts for a special exchange program. She could end up befriending Harry and together they face a new dark threat that combines the magic of the wizarding world and the supernatural powers of the Mikaelsons. Maybe a dark wizard is trying to harness the power of the Mikaelson bloodline for some evil spell, and Harry and Hope must stop it.
One idea could be that Hope, being a powerful witch herself, is sent to Hogwarts on an exchange program. There, she meets Harry Potter and they bond over their shared experiences of being different from their peers. Another plot could involve a dark magic threat that only their combined powers can defeat. They start as strangers, but as they train together, they develop a deep friendship and mutual respect.
A fanfiction could also be about a time - traveling scenario. Elijah Mikaelson travels back in time to the era of the founders of Hogwarts. He gets involved in the early magical society and later crosses paths with a young ancestor of Harry Potter. Their interactions shape the future of both the wizarding world and the Mikaelson family in some unexpected ways.
I really like 'Mystical Alliances' in the 'Harry Potter Elijah Mikaelson' fanfiction genre. It delves deep into the personalities of the characters. For example, Elijah's sense of honor and Harry's determination are well - explored. The author does an amazing job of creating a believable scenario where the two worlds collide, and there are some really exciting action scenes and magical duels.
One idea could be a crossover where Elijah Mikaelson ends up in the wizarding world of Harry Potter. Maybe he's there to seek a powerful magical artifact that could help him in his vampire family's never - ending power struggles. He might initially be seen as a threat by the Ministry of Magic but then prove himself useful in the fight against dark wizards.
There's also 'Potter and the Original'. This fanfiction is unique in that it focuses on how Harry Potter's values and the rather morally ambiguous nature of Klaus Mikaelson interact. It delves deep into the personalities of the characters, exploring how they might influence each other. For example, Harry's sense of justice might rub off on Klaus, while Klaus's street - smart and survivalist nature could teach Harry some new ways of dealing with threats.
One idea could be a crossover with the Vampire Diaries. Hope could meet Elena and they could form an unlikely alliance against a new threat in Mystic Falls. Maybe a powerful witch from another dimension is causing chaos and their combined powers are needed to stop it.
I also like the fanfic 'Mikaelson Heir: Hope'. It focuses on Hope as she steps into her role as the heir of the Mikaelson family. It shows her facing various challenges and how she overcomes them with her unique blend of strength and compassion. There are some great character interactions that make it a must - read for any Hope Mikaelson fan.
