Ash is obviously the central character. Then there are the female characters from the Alola region that often form his harem. Lillie is a very common one. She has a gentle and kind personality and her relationship with Ash can be explored in many ways in the fanfictions. Another is Mallow. Her love for cooking and her energetic nature make her an interesting character to include in the harem. And there's also Lana, with her love for water - type Pokemon.
A common theme in such fanfictions could be Ash's adventures in Alola while building relationships with different characters. Maybe he forms special bonds with his Pokémon and the people around him in a more romantic or friendship - deepening way.
Professor Kukui is another common character. He serves as a guide and mentor to Ash in the Alola region. He might provide Ash with new Pokémon knowledge, especially about the unique Alola Pokémon species. And of course, there are the various Pokémon trainers that Ash meets and battles in the Alola region. These trainers can range from novice trainers just starting out to more experienced ones who pose a real challenge to Ash.
Lillie is really interesting. She starts off as a shy girl but grows a lot in her confidence when it comes to Pokemon. Her relationship with her family and their connection to the Aether Foundation adds depth to her character. Then there's Kiawe, who is very proud of his Alola heritage and his strong fire - type Pokemon. His no - nonsense attitude and his eagerness to prove himself make him stand out. And Sophocles, the tech - savvy kid, is always coming up with cool gadgets to help in Pokemon battles or exploration, which is super fun.
Misty is often in Ash's harem in fanfictions. She has been with Ash since the beginning of his journey and their relationship has a long history. Another common one is Serena. She has strong feelings for Ash and her character development is closely tied to him.
Ash is of course a very common character as he is the central figure. Pikachu is also often included as it is Ash's most well - known Pokémon. Other characters like Misty and Brock might also make appearances as they are Ash's friends and travel companions in the original Pokémon series.
Well, obviously Ash is one of the main characters. He's the protagonist of the Pokémon series and his journey in Alola is the focus. Pikachu is also a main character as Ash's loyal Pokémon partner. In Alola, there could be new friends like his classmates from the Pokémon school, such as Kiawe, Lillie, and Sophocles, who would also play important roles in the fanfiction.
He'll surely meet the Alola region's professors. Also, the local trial captains are very likely to cross paths with Ash. And of course, the regular Pokémon trainers in Alola.
A common theme could be Ash's exploration of the Alola region. The beautiful islands, diverse Pokemon, and unique ecosystems offer a lot of creative potential. Writers might focus on how Ash discovers hidden areas and the Pokemon within them.
Adventure is also a big theme. Since it's set in the Alola region, the fanfiction usually involves exploring the unique islands, encountering new Pokémon, and going on quests. Ash and his 'harem' of friends and Pokémon face various challenges during these adventures.
Serena is a very common character. She has a pre - existing relationship with Ash from the anime and is often a central part of the harem in these fanfictions. Another one is Miette. She is competitive and her interactions with Ash can add an interesting dynamic to the story. Bonnie is also sometimes included. Her innocent and curious nature can bring a different flavor to the harem, especially with her love for Pokémon and her dreams of becoming a Pokémon trainer like Ash.
