A possible crossover could involve the characters' moral compasses. Harry Potter has a strong sense of right and wrong based on his experiences at Hogwarts. Dr Strange, on the other hand, has a more complex view of morality due to his dealing with different dimensions and powers. A fanfiction might explore how they interact when faced with a difficult moral decision, like whether to sacrifice one life to save many.
One interesting crossover could be the use of time - manipulation powers from Life Is Strange in the wizarding world of Harry Potter. For example, a character might use the rewind power to prevent a tragic event at Hogwarts, like a student getting attacked by a dark creature. It would add a whole new dynamic to the magical setting.
It might not be a traditional or 'legitimate' in the sense of being part of the original canons. But in the realm of fanfiction, it's a great idea. Fanfiction is all about creativity and mashing up different universes. Harry Potter has its own set of magic rules and Doctor Strange has his. Blending them could result in a whole new set of magic spells and powers that could be really cool to explore.
One idea could be that a magical anomaly brings Harry Potter to the world of Dr Strange. Harry, with his unique magical knowledge from Hogwarts, could team up with Dr Strange to fight a new dark force that is threatening both their realms. Their different styles of magic would make for an interesting dynamic as they learn from each other.
The magic could blend in interesting ways. Harry's wand - based magic might be enhanced by Dr Strange's more esoteric and hand - gesture - based magic. For example, Harry could use his wand to direct the energy patterns he learns from Dr Strange.
Well, one interesting plot point is when the characters from the two universes first meet. For example, when Harry Potter meets Dr Strange, their different views on magic can lead to some really engaging dialogues. Another is when they have to combine their magical powers to defeat a common enemy. This often involves a lot of creativity in how the spells and magic from both worlds are used together.
Well, in some fanfiction, we might see Anna and Kristoff visiting Hogwarts. They could be amazed by the moving staircases and magical creatures. In reverse, Harry, Ron and Hermione could end up in Arendelle. Hermione might be intrigued by the way Elsa controls her ice powers and try to find a scientific or magical explanation for it. Also, the Dementors from Harry Potter could be compared to the dark forces in Frozen 2, like the mist that Elsa has to face.
One interesting crossover could be the use of magic in the Avengers world. For example, Hermione could use her knowledge of spells to help the Avengers solve a problem that technology couldn't. Maybe she could use a spell to break through an impenetrable force field created by an enemy. Another aspect could be the Avengers characters learning magic. Tony Stark might be fascinated by the concept of magic and try to incorporate it into his technology. Or Thor could share his knowledge of Asgardian magic with the Hogwarts students.
One interesting crossover could be a scenario where Hermione uses her magic to help Elsa control her powers better. Maybe she creates a spell that can soothe Elsa when she's about to lose control.
In some fanfiction, Maleficent might team up with a dark wizard from the Harry Potter universe. They could combine their powers to try and take over both the wizarding world and the fairy - tale land where Maleficent comes from. This would create a complex power struggle with the heroes having to find new ways to combat them.
One interesting crossover could be the characters from Harry Potter visiting Narnia. For example, Harry, Ron, and Hermione might find themselves in Narnia through some magical accident. They could then interact with the talking animals and magical beings there, like how they interact with the magical creatures in their own wizarding world. Maybe they would help the Narnians in a battle, using their unique Hogwarts - taught magic.
