In addition to the ones mentioned, Diantha, the Kalos Champion, is a great character to include. Her elegance and strength in battles can be a focal point. Also, Shauna, Tierno, and Trevor, the friends of Calem or Serena, can bring a lot of fun and friendship dynamics to the story. They can have their own mini - adventures within the larger fanfiction, like exploring a new part of the Kalos region together or trying to catch a rare Pokemon.
Ash Ketchum is always a popular choice. He has so much experience and his journey is well - known. Then there's Pikachu, his iconic Pokemon. Misty and Brock are also great characters to include as they have been part of Ash's journey for a long time. Gary Oak can add a bit of rivalry to the story.
Ash Ketchum is a must - include. His experience and bond with Pokémon can be a great starting point for any crossover. He could bring his Pokémon knowledge to a different world or interact with new characters.
Ash is always a popular choice. His experience and determination can add a lot to a fanfic. You can create new adventures for him, like facing a powerful, never - before - seen Legendary Pokemon.
Obviously, Red and Blue themselves are must - includes. Their rivalry and different personalities make for great storytelling. Green could also be included as she adds an interesting dynamic, especially with her own goals and relationships with the boys.
Definitely Ethan or Lyra, the main protagonists. They are the center of the Gold and Crystal adventures, so it's natural to include them. Then there's Silver, the rival. His complex personality and his own journey of growth make him a very interesting character to write about. Professor Elm is also popular as he is the one who gives the starters and is involved in many pokemon - related research. And of course, the gym leaders like Whitney, Morty, and Pryce are often included because they offer different challenges and have their own unique personalities.
Well, you could write a fanfiction where the evil team in the X and Y games has a different, more complex motive. Instead of just wanting power or to disrupt things, they believe they are saving the Pokemon world from a future threat that only they know about. And the main character has to decide whether to believe them or stop them, all while exploring the beautiful Kalos region and its unique Pokemon.
Definitely Jackie Chan as the main character. He's the heart of the adventures. Alongside him, you could include Captain Black. He can bring in the element of the law enforcement side of things. The Dark Hand members are also popular to include. They can be used as the main antagonists or sometimes even as characters who have a change of heart. And Jade is always a fan - favorite. Her relationship with Jackie and her own growth throughout the story can be explored in the fanfiction.
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.
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.
