One interesting story could be about their adventures together in a new, unexplored region. They might face unique Pokémon and challenges that test their friendship and skills.
You can try fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a wide variety of Pokémon fanfictions, including ones focused on Red and Yellow.
One idea could be a story where Red and Blue have to team up to face a new, extremely powerful and mysterious Pokemon that threatens the entire region. They start off with their usual rivalry but gradually learn to trust and rely on each other more as the adventure progresses.
Professor Oak can be included. He could be the one who gives Red and Blue important missions or tasks. His wisdom and knowledge of Pokemon can guide the two protagonists in their journey. For example, he might provide them with crucial information about a rare Pokemon they need to find to achieve their goals in the fanfiction.
Well, obviously Red and Yellow are the main characters. Red is often depicted as a bold and adventurous character, while Yellow might be more of a gentle and kind - hearted one. They play off each other in the story.
The fanfiction might focus on their journey. Red, being a well - known trainer, and Yellow, with her own special abilities, could be on a quest to discover new Pokemon or solve some mystery in the Pokemon universe. It may also show how their partnership evolves over time, from just acquaintances to really good friends or something more.
One popular theme could be adventure. For example, Red and Yellow might embark on a journey through a fantastical land filled with unique creatures. They could be on a quest to find a special item or save their world from a great evil.
Another way is to give them unique abilities related to their colors. A red - yellow character could have the ability to create heat or light, while a blue - green character could have powers related to water or plants. Their physical appearances could also be inspired by their colors, like having red hair for the red - side character or blue eyes for the blue - side character.
Perhaps it could be a love story. A character from the red or yellow side falls in love with someone from the blue or green side. This love is forbidden in their society because of the long - standing enmity between the two color groups. So they have to fight against all odds to be together.
Blue, Red's rival from Pokemon Red, also has a significant presence in the fanfiction. His competitive nature and his own skills as a trainer make for great storylines. In some fanfiction, he might be shown to have a change of heart or form an unexpected alliance with Red. Also, the various gym leaders from both games can be popular characters. For example, Brock, the rock - type gym leader, could be depicted in new and interesting ways in the fanfiction, like having a secret super - strong Pokemon that he never reveals in the original games.
