There could also be some new characters created specifically for the fanfiction. Maybe a young trainer who idolizes both the Red and Blue protagonists and tries to follow in their footsteps. This character could be the key to unlocking a new mystery in the Pokemon world that involves the combination of the Red and Blue elements, and perhaps has something to do with the 'lemon' aspect, like a special lemon - scented Pokemon or a new type of lemon - themed item.
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 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.
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.
Obviously, Blue and Green are the main characters. Blue is often depicted as a confident and sometimes a bit overconfident trainer. Green, on the other hand, can be shown as more of a strategic thinker.
A possible set of characters could include a healer in a Pokemon village. Salazzle gets injured and is brought to this healer. The healer, who has a gentle and kind heart, takes care of Salazzle. There could also be some of the village elders who are skeptical about having a Salazzle around. And a wandering adventurer who passes through the village and has some knowledge about Salazzle's rare abilities, which helps the healer and the village deal with Salazzle in a better way.
Red and Blue themselves are very popular. Red, being the silent but strong protagonist of Pokemon Red, and Blue, his rival, often star in fanfictions. Their relationship, which is a mix of rivalry and friendship, is explored in many stories.
The main characters are usually Red and Blue. Red is often depicted as the more quiet and determined trainer, while Blue is more outspoken and competitive. Sometimes, their Pokemon also play important roles as secondary characters, like Red's Pikachu or Blue's Eevee (if you choose to give them those particular Pokemon).
One idea could be a story where a unique Pokemon only found in the Red version teams up with a trainer from the Blue version to face a new, powerful threat. Another could be a story about a trainer who discovers a secret connection between the Red and Blue Pokedex that leads to an adventure.
Naruto is always a central character. Alongside him, there could be Legendary Pokemon like Mewtwo or Lugia. Mewtwo, with its powerful psychic abilities, could have some interesting interactions with Naruto. Maybe they start off as rivals due to their strong powers but then end up becoming allies. And there could be a female Pokemon trainer as a main character too, who has a crush on Naruto and tries to show him the wonders of the Pokemon world.
The main characters would obviously be Pikachu, the iconic yellow electric - type Pokemon, and Emogla Lemon. Pikachu is known for its cute appearance and powerful electric shocks. Emogla Lemon, though not a traditional Pokemon, would bring its own unique characteristics to the story. They would be the central focus as their relationship and adventures together are what the fanfiction would be about.
