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.
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.
One interesting story could be about Ash and Pikachu encountering a female Eevee and the adventures they have together. The story might focus on how Ash helps the Eevee evolve into a Sylveon through their strong bond.
One great Ash and Shadow Pokémon fanfiction could be one where Ash discovers a Shadow Pokémon in a mysterious forest. The story could focus on his journey to purify it, with lots of action and his unique bond with Pokémon guiding him.
One interesting scenario could be Ash having a heart - to - heart talk with Pikachu about their journey together. They could discuss their most memorable battles and how their bond has grown over time. Another is when Ash talks to a Legendary Pokémon, like Mew, and they share secrets about the origin of Pokémon or give him hints on how to become a better trainer.
One aspect is the deviation from the usual storyline. In the official Pokémon series, Ash has had many near - wins. So seeing him finally win in a fanfiction is exciting. It gives fans a sense of closure and satisfaction.
One theory could be that Ash has some hidden Pokémon powers that he doesn't fully understand yet. Maybe his ability to bond so deeply with Pokémon is more than just a trainer's skill. Another possibility is that his journey is all part of a grand plan by the Pokémon world to test him as one of their own. It could also be that he has a special heritage that ties him to the Pokémon in a way that no one else does.
Perhaps Ash gets a special ability from a Legendary Pokémon, like the ability to communicate telepathically with all Pokémon. This causes him to be hunted by an organization that wants to use this power for their own gain. With the help of various Legendary Pokémon that he befriends on his journey, Ash has to protect himself and his new power.
In Ash's Pokémon journey fanfic, the battles can be really exciting. The fanfic might introduce new battle strategies that Ash uses. Maybe he combines the moves of different Pokémon in unexpected ways. The relationships between Ash and his rivals can also be a great part. They could have more complex backstories and motives compared to the original series. And the fanfic might show Ash facing more difficult challenges, which makes his journey more thrilling.
One idea could be that Ash discovers a hidden power within Pikachu that allows them to communicate telepathically. This new connection could lead to unique battle strategies and a deeper bond. Another idea is that Ash is on a quest to find a legendary Pokémon that can help him defeat a powerful new villain who is threatening the Pokémon world. He has to travel through different regions, facing various challenges and making new friends along the way.
One example could be a story where Ash's Pikachu becomes overly protective of Ash during a dangerous tournament. It might constantly jump in front of attacks, even when Ash has a plan, causing some comical and tense situations.
