In some Pokemon Sun and Moon Ash harem fanfictions, a popular plotline is Ash getting into some kind of danger and his female friends coming to his rescue. For example, if Ash is trapped by a powerful Pokemon, the girls like Lana using her water - type Pokemon skills, and Sophocles using his tech - savvy knowledge to save him. This not only shows their loyalty to Ash but also deepens their relationships. There are also plotlines where they all participate in Pokemon contests together, with Ash as their unofficial leader and cheerleader.
One common plotline is Ash's various female companions in the Pokemon Sun and Moon series forming a closer bond with him, like Lillie gradually opening up more to Ash and having adventures that bring them closer. Another could be Mallow cooking special meals for Ash, which is seen as a form of her showing her affection in the fanfiction world. Also, the idea of them all traveling together and facing challenges as a group, with Ash at the center of their little 'harem' is quite popular.
One popular theme is adventure. Ash and Lillie might go on various quests together in the Alola region, exploring new places and encountering different Pokemon. Another theme is friendship. Their relationship could develop from just being acquaintances to really close friends who support each other through thick and thin. Also, growth is a common theme. Lillie might overcome her shyness and fear of Pokemon with Ash's help, while Ash could grow in his understanding of different cultures in Alola through his interactions with Lillie.
Well, obviously Ash is the central character. Then there are the female characters from Pokemon Sun and Moon like Lillie, who is often a key part of the harem. She has a gentle and kind personality and her relationship with Ash is a major focus. Mallow is another one. Her love for cooking and her friendly nature towards Ash make her a popular character in these fanfictions. Also, Lana, with her unique bond with water - type Pokemon and her adventurous spirit, is usually involved.
One interesting story could be Ash having a unique adventure in Alola that's different from the main series. Maybe he discovers a new type of Pokémon or a hidden power within his existing Pokémon.
A fanfiction could start with Lillie having a strange dream about a legendary Pokemon. Ash believes her dream could be a sign. So they set out on a quest to find this legendary Pokemon. Along the journey, they meet different characters from the Alola region who give them clues. Their bond deepens as they face difficulties together and eventually find the legendary Pokemon, which turns out to have a special connection to Lillie.
A fanfiction could focus on Ash Greninja's unique form and abilities. For example, it could tell a story where Ash has to rely on Greninja's special skills to overcome a powerful, mysterious Pokemon in the Alola region. This would show the significance of their partnership in the context of Pokemon Sun and Moon.
One possible fanfiction could be about Ash and Lillie's adventure in the Alola region. Maybe they team up to face a powerful new Pokemon that has been causing trouble. They use their combined skills and the unique bond they've developed throughout their journey in Pokemon Sun and Moon.
One great Ash and Serena fanfiction in the Pokemon Sun and Moon setting is 'A New Adventure Together'. It has a really engaging plot where Ash and Serena meet up again in the Alola region and go on a journey to discover new Pokemon. The author does a wonderful job of capturing their characters and the unique charm of the Alola region.
Another plotline could be a Pokémon trainer who has a special ability that makes Pokémon more attracted to them. This ability leads to a collection of Pokémon of different species, both male and female, forming a sort of harem around the trainer. They might all compete for the trainer's attention in a friendly way.
In many such fanfictions, the plot might involve Ash's friends suddenly turning against him due to some false accusations or misunderstandings. For example, they could believe that Ash has been secretly working with an enemy group, which leads to his betrayal.
One interesting fanfiction could be about Ash's adventures in the Alola region where he discovers a rare and powerful Pokemon that isn't in the main series. It could show his journey to train it and how it changes his relationship with his other Pokemon.
