One possible plot could be that Ash stumbles upon the shiny pokemon by pure chance while exploring a new, uncharted area. Maybe he's looking for a specific type of pokemon for a local competition and instead, he discovers this rare shiny pokemon. Another plot could involve the shiny pokemon being in danger from a group of poachers, and Ash has to rescue it. Then, after rescuing it, he forms a special bond with the shiny pokemon which is different from his bonds with his other pokemon.
One interesting plot could be that Ash catches a shiny Pikachu which has some unique powers, like being able to communicate telepathically with other Pokemon. This would change the way Ash interacts with his team and the challenges he faces in battles.
Obviously, Ash is one of the main characters. He is the trainer who catches the shiny Pokemon. His Pikachu also plays a significant role, as it's always by Ash's side and could potentially have some interesting interactions with the shiny Pokemon.
One possible plot is that Latias is injured and Ash finds it. He nurses it back to health, and during this process, they form a bond. Latias then decides to join Ash's team. Another plot could be that there is a tournament where the prize is a special item that can attract Latias. Ash enters the tournament, wins, and uses the item to catch Latias.
There could be a new, evil organization in the fanfiction. Their goal is to use shiny pokemon to power some sort of dark machine or experiment. They target Ash's shiny pokemon because it has a particularly strong energy. This organization would send out their minions to attack Ash and try to capture the shiny pokemon, creating a lot of action - packed scenes in the story.
A great plotline might involve Ash's journey to discover why he can only catch shiny pokemon. Maybe it has something to do with a long - forgotten prophecy or a special power within him. Also, his relationships with his shiny pokemon could be explored deeply. For example, how they communicate differently compared to normal pokemon. This could lead to some heart - warming and exciting moments in the fanfiction.
One possible plot could be that Ash discovers Frilish in a mysterious new region and has to overcome various obstacles like other Pokémon trainers or difficult terrains to catch it.
A self - proclaimed 'collector' of rare pokemon could be a rival. This person has a huge collection of non - shiny but very rare pokemon and sees Ash's shiny pokemon as the ultimate addition to their collection. They would stop at nothing to get their hands on at least one of Ash's shiny pokemon. And of course, there could be other trainers who simply can't stand the fact that Ash has such an amazing ability and they don't.
Well, it depends on the specific fanfiction. Some fanfiction authors might choose to give Ash shiny Pokemon as a way to show his growth or as a special encounter. For example, he could find a shiny Pikachu in a different region in one fanfic, which would then lead to a whole new set of adventures and challenges. It adds an element of surprise and rarity to the story.
Yes, in many Pokemon fanfictions, Ash might be depicted as having a shiny Pokemon. Shiny Pokemon are rare and having one would make for an interesting plot point in a fan - created story.
Another possibility is a Celebi. Celebi is a time - traveling pokemon. Ash could be led to Celebi by some strange time - related events. It would be a challenging catch as Celebi can manipulate time to avoid capture. But with Ash's experience and the unique skills of his pokemon, he might be able to succeed.
