In a Pokemon Ash and Elite Four fanfiction, the story could revolve around Ash getting special training from a mysterious trainer who once defeated the Elite Four. This training helps Ash understand the weaknesses of the Elite Four's Pokémon better. He then uses this knowledge to strategize his battles, leading to some really exciting showdowns.
One possible fanfiction could be about Ash finally facing the Elite Four after a long journey of training. He might have new and powerful Pokémon by his side, and the battles could be intense. For example, his Pikachu could have evolved into a new form, giving him an edge against the Elite Four's strong Pokémon.
In this fanfiction, Ash might face some unexpected challenges before even reaching the Elite Four. Perhaps there are villains who try to stop him from getting to the Elite Four battles. This adds an extra layer of excitement and adventure to the story. Ash would then have to overcome these obstacles while also preparing for the tough battles ahead with the Elite Four.
In fanfiction, if Ash became an Elite Four, he would likely have a much greater influence in the Pokemon world. His skills and experiences would be highly respected. He could use his unique bond with his Pokemon to inspire other trainers. Also, he might be involved in important decisions regarding Pokemon battles and training regulations.
In this fanfiction concept, Ash's adoption could be a very heartwarming story. Maybe he meets an orphaned child during his travels. Ash, with his kind heart, decides to take the child under his wing. It could be a chance for him to pass on his knowledge of Pokemon and values like friendship and perseverance.
In a fanfiction of Ash in the Unova League, it could focus on his relationships with his Pokemon during this journey. Maybe Pikachu has a special moment of growth, or he catches a new and rare Pokemon that becomes crucial in his battles in the league.
A fanfiction could center around Ash having a special training session with the Cerulean Sisters. Since they are known for their water - type Pokémon, they could teach Ash some unique techniques for his own water - type Pokémon. This could lead to Ash's Pokémon evolving or becoming stronger in unexpected ways, and also strengthen the bond between Ash and the sisters.
One possible story could be that Ash and Dawn meet in Kalos and decide to team up for a Pokemon tournament. They bring their unique skills and Pokemon from their respective regions and face many challenges along the way, like dealing with tough opponents and adapting to the new Kalos Pokemon.
One possible fanfiction could be about Ash forming a special bond with Salamence. Maybe Salamence is a wild Pokemon that Ash manages to befriend through his kindness and understanding, which is different from his usual way of catching Pokemon. This could lead to an adventure where they face a powerful enemy together and Salamence's unique abilities help them win.
If Team Rocket turns Ash into a Pokemon, it could lead to a really interesting story. Ash would have to experience the world from a Pokemon's perspective. He'd understand their struggles, like being caught and trained. This could also be a way for him to better understand his own Pokemon and their bond with him. And it would be a wild adventure as he tries to find a way to turn back to his human form.
I'm not a big fan of the'slave' concept in fanfiction as it often goes against the positive and friendly nature of the Pokemon world. However, some might write such fanfictions to explore power dynamics in a different way. But it's important to note that this is not in line with the main themes of the Pokemon series.
Ash is the central figure. The Elite Four members, whose names may vary depending on the region in the Pokemon world, are also main characters. His friends, like Brock or Misty, might also make appearances to support him, even if they're not directly in the battles.
