Well, it might be a story where the magic from Harry Potter and the dark forces of Diablo blend in a strange way. Andariel could be a new kind of threat to the wizarding world. Harry and his friends would have to learn about Diablo's lore and powers quickly. They might even find some similarities between their own magic and the powers in Diablo, like how some protective spells in Harry Potter could be related to the resistance against demonic attacks in Diablo.
It could work by having the two worlds collide. Maybe a portal opens between Hogwarts and the Diablo world. Andariel senses the new magic in the wizarding world and decides to invade. Harry then has to use his skills to stop her. He could use the Marauder's Map to track her movements in Hogwarts, which would be a really cool way to combine the two universes.
Well, it could be really exciting. Imagine Harry Potter facing off against the vampires from Dracula Untold. Maybe the magic in the Harry Potter universe could have new ways of dealing with the vampiric powers. For example, the Patronus charm might be used to repel the vampires, as it represents a positive force against dark creatures. And the wizards could learn about the different rules of the vampire world in Dracula Untold, like how they are created and what their weaknesses are. It would be a clash of two very different but equally fascinating fictional universes.
It could be a wild adventure where the wizards from Harry Potter use their magic to help the Avengers in the final battle of Endgame. Maybe Harry could use the Disillusionment Charm to sneak up on Thanos, or Hermione could use time - turning magic similar to what happened in the Prisoner of Azkaban to change the outcome of some of the events in Endgame.
Well, it could be really interesting. Imagine Harry Potter's magic in the world of Moon Knight. Maybe Harry could use his spells to help Moon Knight in his battles against the bad guys in the Moon Knight universe. For example, he could use the Stunning Spell to immobilize the enemies that Moon Knight is fighting. It would be a cool mash - up of two very different but equally fascinating fictional worlds.
It could be a really exciting fanfic. Imagine Sabrina Spellman, with her witchy powers from the 'Sabrina' universe, meeting Harry Potter. They could exchange spells and magical knowledge. Maybe Sabrina could teach Harry some unique spells from her own magical upbringing, and Harry could introduce Sabrina to the world of Hogwarts. Their combined adventures would surely be full of magic and mystery.
It could be really exciting. Imagine Harry Potter characters in the world of Game of Thrones. Harry could use his magic to face the political intrigue and battles in Westeros. For example, he could use spells to protect himself from the scheming of the Lannisters. And Dumbledore might be like a wise maester, guiding the young heroes in this new and dangerous world.
Well, in such a fanfiction, the characters from Harry Potter would be in for a shock. Yharnam is a very different and dangerous place compared to Hogwarts. Harry, Hermione, and Ron could find themselves facing challenges that require not just their magical knowledge but also a new level of courage. They might meet some of the hunters in Yharnam and learn about their ways of fighting. And perhaps, they could introduce some new magical concepts to the people of Yharnam, like the use of potions for different purposes than just healing.
In a Harry Potter - Hawkeye fanfiction, Hawkeye might be mistaken for a new kind of wizard. He could befriend Harry and his friends. Hawkeye could teach them about non - magical combat skills, while they introduce him to spells and potions. It would be interesting to see how his modern - day weapons and combat knowledge interact with the magical elements of the Potterverse.
In this fanfiction, perhaps there's a spell gone wrong that transports Harry and his friends to a prehistoric world full of velociraptors. They have to use their magic skills to survive in this new environment. Harry might use his Patronus charm to fend off the raptors at first, but then they gradually learn to communicate with the raptors using some kind of translation spell and together they try to find a way back to their own time.
Well, it could be that Mjolnir has been lost in the wizarding world for centuries. Harry, Ron, and Hermione find it during one of their adventures. Ron tries to lift it first but fails. Harry then approaches it, and as he touches it, a surge of power runs through him. This new power allows him to see things in a different way. He can now sense the presence of Horcruxes more easily and also has the strength to break through some of Voldemort's most powerful defenses. The story could revolve around how they use Mjolnir's power in their fight against the Dark Lord without causing too much disruption in the magical balance.
