In a lot of fanfiction, Eevee and Pikachu are the stars. But there can be some where a villain Pokémon like Team Rocket's Meowth becomes a main character as well, but in an antagonistic role. He might try to steal Pikachu or cause trouble for Eevee and Pikachu, which then drives the plot forward as they try to outwit him.
Often, in addition to Eevee and Pikachu, their trainers might also be important characters. The trainers' actions and decisions can influence what Eevee and Pikachu do. For instance, if the trainer sends them on a mission, that becomes the basis of the adventure in the fanfiction. Also, sometimes other Pokémon that are friends with Eevee and Pikachu, like Charmander or Squirtle, might make appearances and play secondary roles in the story.
Obviously, Evil Pikachu is a main character. There might also be trainers who are trying to either stop it or control it. Maybe some other Pokémon that are allied with or against the Evil Pikachu could also be considered main characters.
Obviously, the main characters would be Pikachu and Eevee. Pikachu, the iconic electric - type Pokemon, known for its cute appearance and powerful electric attacks. Eevee, on the other hand, is a very adaptable Pokemon with the potential to evolve into different types. In a fanfic involving lemons, they could be interacting with the lemons in various ways, like Pikachu using its electricity to zap the lemons for fun or Eevee rolling around in a pile of lemons.
The main characters are Eevee, Pikachu, and Serena. Eevee is the protagonist in terms of the love story, Pikachu is the beloved, and Serena is important because she's Eevee's trainer. She could be the one to give advice to Eevee or create situations where Eevee and Pikachu interact more. For example, she might take them to the same Pokémon training sessions.
Obviously, the main characters are usually Pikachu. But sometimes, there could be other Pokémon that play important supporting roles. For instance, a Pichu could be a sidekick or a younger Pokémon that the Pikachus are protecting.
The central characters are Serena's Eevee and Ash's Pikachu. But in many fanfictions, there could be other human characters as well. For example, other trainers that Ash and Serena meet on their adventures. These trainers might have Pokémon that interact with Eevee and Pikachu in various ways, like competing against them or helping them out in a tight spot. Also, there could be Pokémon professors or other important figures in the Pokémon world that are part of the story.
Well, clearly Raichu and Pikachu are the main characters. Sometimes, other Pokémon from their electric - type family or their friends like Ash might make an appearance in the background or play a minor role.
One interesting story could be about Eevee and Pikachu going on an adventure to find a rare Pokémon. They might face various challenges like crossing a big river or getting through a dark forest. Along the way, they meet other Pokémon who help or hinder them.
There could also be other characters that play important roles. For example, some of Ash's friends from the Pokemon series like Misty or Brock might make appearances in the fanfiction. They could offer support or advice to Ash during his adventures with Pikachu.
One possible storyline could be that Pikachu and Eevee start off as rivals in a Pokemon trainer's team. They compete for attention and resources. But then, when facing a powerful common enemy, they realize they need to work together. Their combined electric and various - type moves prove to be a great asset in battle.
Another way is to create a character with a mysterious past that ties into the world of Pikachu and Eevee. Maybe the character was once part of a secret experiment that involved the powers of Pikachu and Eevee. This backstory could drive the character's actions and decisions throughout the fanfiction. They could be on a quest to find out more about their past while also interacting with Pikachu and Eevee. This character could have unique skills or knowledge that they share with Pikachu and Eevee, making the story more engaging. For instance, they might know a special training method for Eevee to quickly evolve into its most powerful form. And they could also have a special bond with Pikachu, like being able to communicate with it on a deeper level than normal trainers.
