One possible fanfiction could be about Sun and Lillie going on an adventure together in the Alola region. They might discover a new and rare Pokemon that only appears during a certain lunar phase. Sun could use his skills as a trainer to protect Lillie from any potential danger, and in the process, their relationship could grow deeper.
A simple plot could be that Sun and Lillie are on a quest to find a special Z - Crystal. They face many obstacles along the way, such as difficult terrain and other trainers. Their relationship develops as they support each other through these challenges.
Realistically, their relationship might start with a simple friendship. Sun helps Lillie become more confident around Pokemon, especially if she was initially a bit scared. As time passes, they start to rely on each other not just in Pokemon - related matters, but also in personal situations. For instance, when Lillie has a problem with her family, Sun is there to support her, and vice versa. Small gestures like sharing food or taking care of each other when sick can also contribute to a deeper relationship.
One interesting plot idea could be that Sun and Lillie go on a journey to discover a new type of Pokemon that has been rumored to exist in a hidden part of Alola. Another could be that they have to team up to save Lillie's mother from some sort of dark force. Maybe they also find a time - traveling Pokemon that takes them back to the past of Alola, and they learn about the origin of some of the local traditions.
In some fanfictions, Lillie is often portrayed as a more delicate and reserved character. Moon, on the other hand, is seen as the bolder one. For example, when they enter a new area full of unknown Pokemon, Moon might be the first to approach and try to interact, while Lillie hangs back a bit.
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.
Obviously, Lillie is a main character. She is often the focus as the title suggests. In these fanfictions, she can be portrayed in various ways, from a shy and timid girl to a strong and fearless trainer.
Well, in this fanfiction, Lillie's return often brings new adventures. Maybe she comes back with new Pokemon skills or knowledge. It could also lead to reunions with old friends in the Pokemon Sun and Moon universe.
A fanfiction might focus on Lillie's relationship with other characters in Pokemon Sun. For example, how she interacts with the protagonist and how their friendship evolves over time. They could go on adventures together, and Lillie could learn important life lessons from these experiences. Also, her family background could be explored more deeply in the fanfiction, which could add more layers to her character.
One possible storyline could be Lillie and Moon teaming up to discover a new and rare Pokemon species in the Alola region. They might face challenges like rough terrains and other trainers who also want to find this Pokemon first.
