A court jester can add some humor. He can be the one who sees through the courtly pretenses and gives the emperor some down - to - earth advice in a comical way.
You could include a passionate and talented lead dancer like Mia from 'Step Up' - type character. Also, a strict but fair dance instructor who has high expectations for their students. And don't forget about the rival dancer who is always trying to outshine the main character.
Captain America is a popular choice for the Avengers side. His leadership skills and unwavering moral compass can provide guidance to the combined team. On the mutant side, Jean Grey with her telekinetic and telepathic powers can be a very interesting character to write about. Her struggle with the Phoenix Force can add a lot of depth to the story.
Giovanni, the leader of Team Rocket, can add a lot of drama and conflict. You can explore his backstory more deeply or have him be involved in a new, devious plot that the protagonist has to stop. Another great character is Misty. Her strong personality and love for water - type Pokemon can bring interesting dynamics to the story.
Ash Ketchum is an obvious choice. He has so much experience with Pokemon and his journey could easily be adapted into a musical story. His Pikachu could be the star of the musical with its cute appearance and electric - based musical abilities that could be imagined, like creating lightning - like light shows during the musical.
Definitely Pikachu. Pikachu is one of the most recognizable Pokémon, and having it interact with Arceus in a crossover would be really cool. It could be like a small, cute Pikachu following around the all - powerful Arceus.
Definitely Naruto and Toriko themselves. They are the main characters of their respective series, so having them interact is a must in most fanfictions.
Another popular Pokemon to include could be Charizard. It's big, strong, and has a cool design. From Avatar, Katara could be included. Her waterbending skills and strong personality would make for great interactions with Pokemon. Maybe she could use her waterbending to heal injured Pokemon.
Sasuke is always a popular choice. His complex relationship with Naruto can be further explored in fanfiction. You can create new scenarios where they have to overcome more challenges together or face off against each other in different ways.
The Prince himself is, of course, a must - include. His skills and his journey are central to the Prince of Persia concept.
Ash Ketchum is a must - include. He's the face of the Pokemon anime and his journey has inspired many fanfiction ideas. Misty and Brock are also great choices as they are Ash's long - time companions. Another popular character could be Gary Oak, Ash's rival. He adds a lot of competitiveness to the story. And of course, Team Rocket, Jessie, James, and Meowth, who are always causing trouble and adding some humor to the plot.
