What are some interesting crossovers in 'Harry Potter Willy Wonka fanfic'?

Dumbledore could also be a popular character to include. His wisdom and power would make for an interesting interaction with Willy Wonka. He could be intrigued by Wonka's magic, which is different from the wizarding magic in the Harry Potter series. And the Weasley twins might be included as they could get up to all sorts of mischief with Wonka's magical candies.

One idea could be that Charlie discovers a long - lost recipe of Willy Wonka's that leads to a new type of magical candy. This new candy could have the power to make people see their fondest memories. Charlie then has to protect this recipe from a rival chocolatier who wants to steal it and use it for their own gain.

Another possibility is a crossover with 'The Chronicles of Narnia'. The children from Narnia could enter the chocolate factory. They might be amazed by the talking candies and the different rooms. And perhaps Willy Wonka could create a special chocolate that has the power to transport you to Narnia, creating a connection between the two magical worlds.

One idea could be exploring the backstory of the Oompa - Loompas. Maybe they had a life before coming to the chocolate factory that was full of adventure. Another could be a story where Charlie Bucket has to save the factory from a new, mysterious threat that even Willy Wonka can't handle on his own. And also, a fanfiction about a new character who enters the factory during one of the tours and has a special power that affects all the magical candies.

One idea could be that Charlie discovers a hidden room in the chocolate factory filled with magical candies that can grant wishes. He and Willy Wonka then have to protect these candies from a rival chocolatier who wants to steal them for their own gain.

One interesting idea could be a crossover with 'Lord of the Rings'. Imagine Harry and his friends in Middle - earth, facing the dark forces there. They could learn new magic from the wizards in Middle - earth or teach their own brand of magic. Another idea is a crossover with 'Percy Jackson'. The demigods and the wizards could team up to fight a common enemy that threatens both the magical and the mythological worlds. Maybe they'd have to combine their powers and strategies.

One interesting crossover could be the use of Stargate's technology in the Harry Potter universe. For example, the Stargate could be a magical object that transports wizards to different wizarding worlds or even other planets. Another idea could be that some Stargate characters end up at Hogwarts and have to learn magic to survive. They might introduce their own technology and knowledge, creating a whole new dynamic within the school.

One interesting crossover could be the use of magic in the Avengers' world. For example, Harry Potter characters could teach the Avengers some basic spells to help them in their battles. Another aspect could be the characters' personalities interacting. Hermione might befriend Bruce Banner and they could exchange knowledge about science and magic.

Well, a crossover could involve the magic of the two universes mixing. In Middle - earth, the magic is more nature - based and ancient, while in the Harry Potter world, it's more structured with spells and potions. If they were combined, new forms of magic could be created. For instance, a spell that uses the power of the ents (from Middle - earth) and the magic of a Hogwarts spell. Also, the different magical creatures could interact. Hippogriffs and eagles from Middle - earth could have some interesting encounters.

A really unique crossover idea in Harry Potter and Batman fanfic could be that the magic in the Harry Potter world starts to seep into Gotham City. Batman has to deal with magical threats that he has never faced before. He might have to team up with some of the Hogwarts students or professors to figure out how to stop the chaos that the magic is causing in his city. This would be a great way to blend the two worlds together and create a whole new set of challenges for Batman.
