Obviously, Ash is a central character since it's about him vomiting. Pikachu is likely to be there too, probably looking worried about Ash. Maybe Misty would be in the story as well, scolding Ash for getting into a situation that made him vomit or trying to take care of him.
Often, Nurse Joy would be included. Since she is known for taking care of Pokémon, she could also be involved in taking care of Ash when he is vomiting. Professor Oak might be mentioned as well, perhaps Ash sends word to him about what happened. And of course, different Pokémon from Ash's team and those he encounters in the area where the vomiting incident occurs could also be part of the fanfiction.
Brock could be another common character. He might be the one trying to find a remedy for Ash's vomiting. In addition, Team Rocket could also make an appearance. They could either be the cause of Ash's distress, like setting up a trap that makes him sick, or they could be there to witness it and have some comical reactions. There might also be other Pokémon trainers that Ash meets during his journey who are either helpful or just bystanders when he vomits.
Well, perhaps in a fanfiction, Ash is exploring a new region and comes across a poisonous plant. Unknowingly, he breathes in the fumes or touches it and it makes him ill, resulting in vomiting. Or maybe a Pokémon he befriends has an ability that has an unexpected side effect on Ash, like making him nauseous and causing him to vomit. There are many creative ways that authors can come up with in Pokémon Ash Vomiting fanfiction.
Mewtwo is also a common Legendary Pokémon in Ash - related fanfiction. Mewtwo's complex personality and its powerful psychic abilities make for interesting interactions with Ash. There can be stories about Mewtwo respecting Ash's bond with his Pokémon and joining him on a journey, or even testing Ash's worthiness.
One common theme is friendship. Ash forms strong bonds with Pokémon that are like mates. For example, his relationship with his starter Pokémon is often explored in a deeper way, showing loyalty and mutual understanding.
Many fanfictions pair Ash, in his reincarnated state, with new characters as well. Sometimes there are powerful Pokémon trainers or even mysterious characters from different dimensions. These new pairings can introduce fresh storylines and dynamics, like the new character guiding Ash through his new, reincarnated journey or being in conflict with him over different goals.
One common character is of course Ash himself. Another could be Pikachu, as it is Ash's most loyal Pokémon. There might also be Misty or Brock, as they are Ash's long - time friends and could play a role in the adoption story, either being supportive or having doubts about the new situation.
I don't think it's a particularly common way of expressing it. In the Pokémon fanfiction community, you're more likely to see statements like 'My fanfic features Ash in a new adventure' or 'There's a great fanfic with Ash as the main character'. This statement is a bit too basic and not very descriptive compared to how people usually talk about their fanfics involving Ash. However, it could potentially be used in a more general sense when referring to the fact that Ash is often included in Pokémon fanfiction.
Yes, it can be. Since Ash is a very popular character in Pokémon, there are a lot of fanfictions centered around him. So, this statement could be common as it simply states the fact that Ash is often the focus in Pokémon fan - made stories.
Eevee is also common. With its various evolutions, it can add a lot of variety to the harem dynamic. Different Eeveelutions might represent different personalities within the harem, and the idea of an Eevee evolving based on its relationship with the trainer can be an interesting plot point.
Some fanfictions focus on Ash's relationships with other trainers in the context of being a legendary trainer. He could form alliances with other powerful trainers, and together they face challenges like tournaments where the stakes are not just victory, but also the fate of the Pokémon world.
Obviously, Ash is a common character. His friends like Brock and Misty might also make appearances. They could offer their own skills and knowledge to help Ash in his ranger adventures.
