In a crossover with 'Peter Pan', Peter himself would be a great addition. He could fly around the chocolate factory, causing mischief among the Oompa - Loompas. Wendy could also be there, and she might befriend Charlie and help him understand some of the more complex parts of the factory. Tinker Bell could add some magic sparkles to the already magical environment.
For a crossover with 'Snow White and the Seven Dwarfs', Snow White would be a lovely addition. Her kindness could win over the Oompa - Loompas, and she could sing to the candies to make them grow or change. The dwarfs could be like little helpers in the factory, using their mining skills to find special ingredients for new chocolates.
If it's a crossover with 'The Little Mermaid', Ariel could be a fun character. She could be curious about the world above water and see the chocolate factory as a new and exciting place. She might be a bit out of her element, but her love for new things could lead to some interesting interactions with Willy Wonka and the other characters. Flounder could tag along, being all wide - eyed and scared in this strange new land.
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.
Obviously, Willy Wonka himself is a must - include. He's the heart and soul of the factory. Charlie Bucket is also great as he represents the pure - hearted visitor. The Oompa - Loompas add a lot of fun and mystery with their strange songs and unique appearance. Veruca Salt can bring in some drama as she was the spoiled brat in the original story.
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.
Definitely Captain America. His old - fashioned values would contrast with Iron Man's more modern, tech - based approach in Armored Adventures. It could lead to some interesting conflicts and character development as they work together.
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.
Luke Cage would also be a great addition. His unbreakable skin and street - smart attitude could bring a new dimension to the story. He could act as a moral compass for The Punisher at times, while also respecting his determination to clean up the streets.
A fearless warrior maiden could also be included. She could be an equal to the ancient defender in combat skills and provide a different perspective. They might have a bit of a friendly rivalry at first but later become great friends and allies.
A tough and experienced park ranger. They would have knowledge of handling dangerous animals and could be a key figure in trying to deal with the Indoraptor in a crossover situation. For instance, if the crossover is in a forest - like setting, the ranger could use their tracking skills.
Definitely Daredevil. As I mentioned before, their different moral compasses would create great tension. Elektra could also be included. She has a more ambiguous moral code and her skills would make her a formidable presence in a story with the Punisher.
Well, characters from other Disney shows like Raven from 'That's So Raven' could be great. Raven's psychic abilities could create some really interesting interactions with Hannah. Also, characters from 'High School Musical' like Troy. They could have a singing competition or collaborate on a musical project. And what about Kim Possible? Her spy skills and Hannah's secret identity as a pop star could lead to some exciting adventures together.
