Clemont, the Gym Leader in Lumiose City, is also popular. His inventions and his role as a Gym Leader can add an interesting dynamic. For example, the main character could help him test a new invention that has an impact on Pokemon battles in the Kalos region.
Professor Sycamore is another great character to include. He can provide knowledge and guidance to the main character. His research on Pokemon in the Kalos region can be a central part of the story.
Definitely Serena. She's a well - known character from the Kalos region. Her journey as a Pokemon trainer and her relationship with Ash can be explored further in a fanfic.
Ash Ketchum is always a popular choice. His experience and determination can make for great storylines in the Kalos League. Serena could also be included, especially if you want to explore a romantic sub - plot or her growth as a Pokémon trainer.
Ash Ketchum is a classic choice. His experiences and growth throughout his journey can serve as inspiration or even be part of a parallel story in the fanfic. You could also include his Pikachu, which is an iconic Pokemon.
Ash Ketchum is always a popular choice. His long - running journey through different Pokemon generations provides a lot of material for fanfic writers. You can write about his new adventures, or what if scenarios like what if he had chosen a different starter Pokemon in a certain generation.
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.
Team Galactic's Cyrus. He is a complex villain with a grand plan. A fanfic could delve into his motives more deeply, or perhaps show a different side of him, like what led him to his extreme beliefs in the first place. His interactions with the main characters could also be a major part of the story.
Serena is also very popular. Her relationship with Ash and her own growth as a Pokemon trainer add depth to the stories. She has her own dreams and goals in the Kalos region, which makes her a great character to follow in fanfiction.
The main character from the game, of course, is a popular choice. Also, Cyrus from Team Galactic is often included as he is such a complex and interesting villain. And Dawn or Lucas, depending on the version, are great to have as they are the typical Pokemon trainers that players can relate to.
Pikachu is always a popular choice. It's so well - known and cute, and imagining it in a transformation scenario, like turning into a human or another Pokemon, can be really interesting. Another popular character would be Charizard. Its cool and powerful look makes for great transformation stories. And of course, Mewtwo. Given its mysterious origin and powerful psychic abilities, a TG story involving Mewtwo could be very engaging.
In Pokemon, Pikachu is always a popular choice. It's the mascot of the franchise and super recognizable. In Digimon, Agumon is really popular. So including them in a fanfic would draw a lot of readers. Also, characters like Ash from Pokemon and Tai from Digimon are well - loved and would be great to have in a crossover fanfic as they could lead the combined adventures.
It's hard to say for sure without reading it, but it could be a young trainer as the main character, perhaps with their starter Pokemon.
