Lance, the dragon - type master, could be a powerful and mysterious character in the fanfiction. His skills and knowledge of powerful Pokemon could either help or hinder Ash and Red. And then there's Pikachu, of course. Pikachu is Ash's most loyal partner and could have some really cute and exciting interactions with Red's Pokemon, like when they play together or team up in battles.
Gary Oak could be an interesting addition. His rivalry with Ash is well - known, and his skills as a Pokemon trainer would make him a valuable character. Then there's Blue, who has a connection to Red. His different approach to Pokemon training compared to Ash and Red could create some interesting storylines. And don't forget about Professor Oak. He could provide guidance and knowledge to both Ash and Red, and his presence always adds a sense of wisdom to the Pokemon world.
There are also often appearances from various Gym Leaders. They can serve as either allies or rivals to Ash. For instance, a Gym Leader might challenge Ash to a battle to test his newfound power, or they could join forces with him to take on a greater evil that threatens the Pokemon world.
Pikachu is a must - include. It's Ash's most iconic Pokemon. For Sawyer, his Slurpuff could be great. Also, Greninja for Ash would add a lot of action scenes. Sawyer's Sceptile could also be interesting to include as it can show the different training styles between them.
The main characters are Ash and Red. Ash, who has been traveling through different regions in the Pokémon world, and Red, who has his own legend in the Pokémon games. In a Kalos - themed fanfiction, they will be the ones driving the story forward. They may encounter other trainers, Gym Leaders, or even Team Flare members, but it's their actions and decisions that will shape the narrative.
Gary Oak is often a popular character in fanfiction related to this. In the 'pokemon red and ash' fanfiction, he can be portrayed as a rival to Ash in new and different ways. Maybe he has a different motivation or goal in the fan - created storylines. Misty and Brock are also popular as they are Ash's long - time companions, and their relationships with Ash can be explored further in these fanfictions.
Obviously, Red and Ash are the main characters. Red is known for his strong Pokemon training skills in the Pokemon games. Ash, from the anime, has his own unique charm and determination. Their relationship as brothers forms the core of the fanfiction. There might also be other supporting characters like their Pokemon, for example, Pikachu which is Ash's iconic Pokemon and maybe Red's Charizard. And perhaps their friends or rivals from their respective storylines could also make appearances to add more depth to the story.
Professor Oak would be an excellent addition. He could provide valuable advice to Ash and Lyra, maybe even send them on a special mission. Also, Dawn could be included. She could be a friend who joins them on their adventure for a while, bringing her own unique Pokemon and skills to the story.
Pikachu is a must - include. It's Ash's most iconic Pokemon and always adds a lot of charm and power to the story. Brock could also be great as he has a lot of knowledge about Pokemon and can offer valuable advice.
Red has a reputation for being an extremely skilled trainer. However, Ash has a unique bond with his Pokémon. If it was a battle, Ash's Pikachu might be able to pull off some unexpected moves against Red's Pokémon. But Red's Charizard is also very powerful. So, in the end, it might be a draw if both trainers are evenly matched in terms of skill and strategy.
The main characters would surely include Ash. In Pokemon Red, the rival character, Gary (or whatever name you choose for the rival in the game), could also play a major role. And of course, the various gym leaders from Pokemon Red. They could have different encounters with Ash, some might be friendly and help him, while others could be more challenging opponents. Also, Professor Oak might be involved, as he is connected to both Ash's world and the world of Pokemon Red in some ways.
