Jafar could be the main villain. He might follow Aladdin to the chocolate factory out of his jealousy and thirst for power. He could try to take over the factory, using his dark magic to control the Oompa - Loompas and manipulate Willy Wonka's inventions for his own evil purposes. Jafar might also be tempted by the unique magical properties of the candies and try to use them to enhance his powers even further.
It could be a new character created specifically for this crossover. Maybe a disgruntled former Oompa - Loompa who was fired by Willy Wonka and has now teamed up with one of Jafar's minions. They combine their knowledge of the factory's secrets and Jafar's dark magic to create chaos. This villain would be motivated by revenge against Willy Wonka and the desire to rule both Agrabah and the chocolate factory world.
In an Aladdin and Willy Wonka crossover fanfiction, it could start with Willy Wonka inventing a new type of chocolate that has the power to transport people to different magical realms. One piece of this chocolate accidentally ends up in Agrabah. Aladdin, being the curious one, eats it and is transported to the chocolate factory. There, he meets Willy Wonka and all the Oompa - Loompas. They find that Aladdin's street - smart skills and knowledge of magic from his own world can help solve some problems in the factory, like dealing with a new type of mischievous candy - creature that has been causing chaos. Meanwhile, Willy Wonka is fascinated by Aladdin's lamp and the concept of three wishes, and they exchange ideas about how to make the most of magic and creativity.
Mr. Wonka himself would be fascinating. His eccentric personality would contrast with the more down - to - earth characters in Zootopia. He could introduce the animals to all sorts of wild and wacky inventions and treats. And seeing how he interacts with the different species in Zootopia, whether he's impressed by their unique abilities or finds them useful for his factory in some way, would be really cool.
Willy Wonka himself could be the main villain. He has all the knowledge of the factory and could use it to torment those who enter.
One great 'Willy Wonka Crossover Fanfiction' is the one where he crosses over with Alice in Wonderland. It's really interesting to see Willy Wonka in the topsy - turvy world of Wonderland, interacting with the Mad Hatter and the Cheshire Cat. The author does a great job of blending the two unique universes together, with Wonka's strange candies fitting right in among the oddities of Wonderland.
The Oompa - Loompas would definitely be main characters. They could play the role of protectors or guides for the baby. Charlie Bucket could also be a main character, perhaps as an older brother - like figure to the baby. Veruca Salt might be there too, causing trouble as she usually does and trying to get the baby on her side to help her get more candies.
To write a great 'Willy Wonka Crossover Fanfiction', focus on character development. If you're crossing over with, say, The Lord of the Rings, think about how Willy Wonka would fit into Middle - earth. He might be seen as a strange wizard - like figure with his own brand of magic. Have him interact with characters like Frodo or Gandalf. Let their different personalities clash or complement each other. Also, pay attention to the setting. Describe how the chocolate factory would look if it was in Middle - earth or how Middle - earth would react to Wonka's candies. You can add a lot of humor and drama to the story by playing with these elements.
Interactions in this crossover would be diverse. Willy Wonka would be intrigued by the Titans' powers. He might ask them to use their abilities to help him with some new creations in the factory. For instance, he could ask Starfire to use her starbolts to heat up a special chocolate. The Oompa - Loompas could be both entertained and a bit scared of the Titans at first. They might sing songs about the Titans' strange appearances and powers. The Titans, in turn, would have to adapt to the Oompa - Loompas' unique culture within the factory and find a way to work together to have a positive experience.
The Oompa - Loompas are a must - include. They can add humor and a touch of mystery to the story. For example, they could be the ones to guide the reader through the factory when Willy Wonka is busy.
One possible plot could be that Judy Hopps, being the curious and adventurous rabbit she is, somehow stumbles into Willy Wonka's chocolate factory which has mysteriously appeared in Zootopia. The animals are in awe of the magical candies and treats, but there are also some rules that they need to follow, much like in the original Willy Wonka story. For example, the golden ticket concept could be adapted where certain animals find tickets that allow them access to a special part of the factory, and there could be some lessons about greed and kindness along the way.
Well, it could be that there is a rift between dimensions that pulls the Arrowverse into the Willy Wonka universe. The characters from Arrowverse are confused at first, but then they realize they need to help Willy Wonka with a mystery in his factory. There could be some sort of dark magic involved that is affecting the production of the delicious treats. The Arrowverse characters would bring their own unique skills and personalities to solve the mystery, all while experiencing the wonder and strangeness of the Willy Wonka world.
