One possibility could be a magical encounter. Maybe he stumbles upon a rare and powerful Pokemon or a mystical artifact that bestows him with wings. It could also be a result of some genetic experimentation by a mad scientist in the Pokemon world who targets Ash for an experiment gone wrong (or right, in this case of getting wings).
The wings could be used in combination with his Pokemon's attacks. For example, he could use his wings to create updrafts for Flying - type Pokemon to enhance their attacks. Or he could distract opponents while his Pokemon sneaks up from behind. Also, the psychological impact on his opponents would be significant. Seeing Ash with wings would be unexpected and might throw them off their game, giving Ash an edge in battles.
Ash could be a Pokémon trainer with a different starting point in this fanfiction. Born in 1987, by 1997 he might have already made a name for himself in local Pokémon battles. He could have a team of Pokémon that he rescued from difficult situations, like a Charmander that was abandoned by its trainer. His story could revolve around giving these Pokémon a second chance and proving that Pokémon don't need to be 'perfect' to be strong.
Another of Ash's Pokemon like Charizard can have a proud nature in fanfiction. This pride can sometimes lead to conflicts with Ash, as it might not always follow his commands immediately. But it also makes Charizard a very determined fighter. When it finally decides to cooperate with Ash, it becomes an even more formidable force.
In many Pokemon fanfictions, Ash's father is often left as a mystery figure. Some fanfictions might create an elaborate backstory for him, perhaps making him a powerful Pokemon trainer in a far - off region. He could be someone who had to leave Ash and his mother for some noble or dangerous quest related to Pokemon.
Pikachu is a very likely candidate. It's Ash's most iconic Pokemon and has a deep bond with him. Whenever Ash is in trouble, Pikachu often steps up to protect him.
One popular type of Pokemon Ash and Pikachu fanfiction might be adventure - based. For example, Ash and Pikachu could embark on a journey to a new and mysterious region filled with undiscovered Pokemon species. They might face challenges like difficult terrains and powerful, previously - unseen Pokemon. In this fanfiction, Pikachu's electric powers could be enhanced in some unique way, and Ash would have to strategize differently to overcome the obstacles.
In a fanfiction about Ash born in 1987 and his situation in 1997, we could see an alternate story where Ash is not the typical rookie trainer. Since he's a bit older than in the original, he might be more knowledgeable about Pokémon lore. He could be on a quest to uncover some ancient Pokémon secrets in 1997. He might travel to different regions, not just for battles but also to study old Pokémon texts and artifacts, and along the way, form an unusual team of Pokémon that are attracted to his in - depth knowledge.
One popular aspect of Alola fanfiction with Ash could be his growth as a trainer. In the Alola region, Ash had unique experiences. Fanfiction might explore how he further developed his skills, formed new bonds with Pokemon, and interacted with the local culture. For example, his relationship with Pikachu might be delved into deeper, showing how they overcame new challenges together in the Alola setting.
Ash's loss could lead to a change in his journey. Instead of just aiming for Pokémon battles and championships, he might focus more on self - improvement and understanding his Pokémon better. He could travel to new regions to learn different training techniques or seek out wise Pokémon trainers who can give him advice on how to avoid such losses in the future.
One possibility could be a curse or a blessing from a powerful being. Maybe Naruto encounters a god - like entity during one of his adventures who bestows the angel wings upon him as a way to test his character or give him new powers to face an upcoming threat.
