Yes, there are likely some out there. Fans often create crossover fanfics that combine different universes like 'Hitman' and 'Harry Potter'. These can be really interesting as they blend the magic and mystery of 'Harry Potter' with the stealth and assassin - like nature of 'Hitman'.
If Loki were to enter the Harry Potter world, it could significantly disrupt the plot. His ability to deceive and manipulate could lead to many characters making wrong decisions. For instance, he could trick Dumbledore into believing a false prophecy, which would send Harry and his friends on a wild goose chase.
Sure, it's quite possible. Fanfiction writers love to blend different fictional worlds. In a 'The Mummy (2017)' and 'Harry Potter' crossover, we could see the mummy's powers being pitted against the spells of Hogwarts students. Maybe the mummy is brought back to life in the wizarding world and causes chaos. There are endless possibilities for interesting storylines in such a crossover fanfiction.
One idea could be that Megara, with her sharp wit and street - smart nature, finds herself in the wizarding world of Harry Potter. She could team up with Harry and his friends, using her own unique skills to help them out in a dangerous situation, like facing a new dark wizard threat.
One idea could be that Tinkerbell finds her way into the wizarding world of Harry Potter. Maybe she gets accidentally transported there by some magical mishap. She could use her fairy magic in Hogwarts, like helping to repair broken objects in a more sparkly and unique way compared to the Reparo charm.
I'm not sure if there is a specific crossover fanfic between Harry Potter and Pepper Potts. It's quite an unusual combination as they belong to different fictional universes. But the world of fanfiction is vast, so it's possible that someone out there has created one.
A popular one is 'Fem Harry and the World of Middle - earth'. This fanfic is really interesting because it crosses over the Harry Potter universe with Tolkien's Middle - earth. Here, Fem Harry has to adapt to the very different cultures and magic systems in Middle - earth, and there are some great character interactions that add depth to the story.
Yes, it could be. It's a very interesting and unique concept. Combining Harry Potter with the Riddler from Batman is quite unexpected. It might involve putting Harry Potter in a situation where he has to solve riddles like the Riddler creates, or perhaps there are elements of mystery from the Riddler's world incorporated into the magical world of Harry Potter.
One idea could be that the Avengers are somehow transported to the wizarding world. They might be initially confused by the magic but then start to work with the Hogwarts students and teachers to fight a common enemy, like a dark wizard who has also harnessed some sort of Muggle - like technology to become even more powerful. For example, Voldemort could team up with Hydra remnants to create a super - weapon that threatens both the magical and non - magical worlds.
A fun concept could be a Transylvanian wizard coming to Hogwarts as an exchange student. This wizard has a pet dragon that is different from the ones in the UK. He brings with him knowledge of Transylvanian magic, like how to use the power of the full moon in a different way than British wizards do, which intrigues Harry and his friends.
