One common theme is friendship. Red and Blue often start out as rivals but gradually become close friends. Another theme is adventure. They usually go on some kind of journey together, facing challenges and growing as trainers.
Red and Blue themselves are often popular characters. Their rivalry and different approaches to Pokemon training can make for great stories. Also, Professor Oak is a well - liked character as he often plays an important role in the fanfic, like giving advice or providing new Pokemon to trainers.
One popular theme is the adventure of the trainers from the blue and red versions teaming up. They might face a new, powerful and mysterious pokemon that wasn't in the original games. Another theme could be about the friendship or rivalry between the characters from the two versions evolving in new and unexpected ways. For example, they could have a competition to see who can catch a certain number of a rare pokemon first.
Another alternative is fanfiction that delves into the backstories of Red and Blue. For example, stories about their early days as Pokemon trainers, how they first caught their starter Pokemon, and the challenges they faced while training in the Kanto region. This type of fanfiction can be really interesting and stay true to the spirit of the Pokemon games.
In some fanfictions, the trainers from Red and Blue versions might participate in a special tournament that includes Pokemon from both games. It could be a high - stakes competition where they not only battle for the championship but also to prove which version has the better Pokemon. This could lead to interesting rivalries and friendships between the trainers.
One popular character is often the player - character from Pokemon Red or Blue, who is now exploring Alola. Their experience and knowledge from Kanto make them stand out in the new region.
One interesting storyline could be about a trainer who catches a rare Pokemon in the Red and Blue regions and has to protect it from an evil team. Another could be a story of two rival trainers from the Red and Blue versions who end up having to team up to save the Pokemon world.
Sometimes, the starter pokemon like Bulbasaur, Charmander and Squirtle also get a lot of focus. Their growth and development as they accompany their trainers through the adventures in the fanfiction can be a central part of the story. For example, a fanfic might tell the story of how a Bulbasaur overcomes its weaknesses and becomes a powerful Venusaur in the context of the blue and red pokemon world.
One popular 'Red x Blue Pokemon fanfiction' is 'A Bond Beyond Battle'. It focuses on their journey together, exploring how their different personalities complement each other in the Pokemon world. They face various challenges and grow closer as friends and partners.
