What are some interesting plot ideas for Harry Potter and Dr Strange slash fanfiction?

One plot idea could be that Harry discovers a hidden portal in Hogwarts that leads to Doctor Strange's Sanctum Sanctorum. He then has to learn the ways of the mystic arts to close a rift that is endangering both the wizarding world and the world of Doctor Strange. Along the way, he teams up with Doctor Strange and they exchange knowledge about their respective magics.

Maybe there's a crossover where the Infinity Stones are somehow related to powerful magical artifacts in the Harry Potter world. The Avengers and the Hogwarts students could team up to keep these powerful items out of the wrong hands. This would involve characters like Captain America learning about the wizarding world's history and culture.

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.

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 idea could be that Harry discovers he has the power to time - travel in a very unique way, not like the Time - Turner. He can enter different eras of the wizarding world's history and has to solve mysteries that are linked to his present. Another could be that he has a strange power of telepathy but only with dark creatures, which he uses to negotiate peace treaties. Maybe he also has the power to manipulate elements in a way no other wizard has, like creating new magical plants by combining the powers of fire and water.

One idea could be a wizard from the Harry Potter world accidentally stumbling into Forks. Maybe he has some unique magic that the vampires in Twilight are intrigued by. For example, he could have a spell that reveals the true nature of vampires in a new way, causing chaos and new alliances.

One idea could be a what - if scenario. What if Strange and Christine had a moment of passion during a time - traveling adventure? Maybe they kiss in a parallel universe where they're not bound by the normal rules of their relationship in the main MCU timeline.

One interesting story could be where Harry Potter, with his magic from the wizarding world, teams up with Stephen Strange in the multiverse. Maybe they combine their powers to fight a common magical threat that spans across different dimensions. For example, a dark entity that is causing chaos in both the Marvel universe and the wizarding world.

One interesting idea could be the exploration of a unique friendship between characters from Harry Potter and Riddick universes. For example, how Harry's magic might interact with Riddick's survival skills in a dangerous situation. Another could be the creation of a new magical - like world that combines elements of both, like a prison in the wizarding world where Riddick - like characters are held.

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.
