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.
There are quite a few on various fanfiction websites. 'Ash and His Shiny Team' is a fanfiction where Ash gradually builds a team of shiny Pokemon. He starts with a shiny Bulbasaur that he finds in an unexpected place. As he travels, he meets other shiny Pokemon and they join his team. The story then revolves around how he trains and battles with this unique team. There's also a fanfic called 'Shiny Dreams of Ash' where Ash has a dream about shiny Pokemon and then starts his quest to find and catch them, which leads to many exciting adventures.
It's quite variable. Ash could obtain a shiny Scyther through a trade with another trainer or as a gift from a mysterious Pok茅mon expert in the fanfiction world.
Well, perhaps Ash could gain new and amazing powers. Shiny pokemon often have special abilities or appearances, so if Ash turns into one, he might be able to fly like a shiny bird - type pokemon or have super strength like a shiny fighting - type. He could also use his new form to communicate better with pokemon, since he'd be more like them.
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.
In this fanfiction, Ash could start in a mysterious forest and spot a shiny Celebi. Celebi, being a time - traveling Pokemon, could take Ash on a journey through different time periods in the Pokemon world. He might see how the Pokemon world has evolved over time, meet some of his ancestors or future versions of himself, and have to solve various problems in each time period to keep the balance of the Pokemon world.
I'm not sure specifically as there could be many interpretations. It might be about Ash's encounter with a shiny Feebas in the Pokémon world, perhaps detailing their adventures together or how Ash comes to obtain the shiny Feebas.
