A fanfiction could be about Lillie's attempts to create a new form of Pokemon battle. She might be inspired by the unique environment of Alola and come up with a battle style that combines elements of the local culture. This could attract the attention of other trainers and even lead to a new Pokemon tournament being created in Alola.
One idea could be a story where Lillie discovers a hidden power within herself during an adventure with the protagonist in Pokemon Sun. Maybe she can communicate with a rare and powerful Pokemon that no one else can. This could lead to a series of events where they have to protect this Pokemon from an evil organization.
One interesting plot idea could be a story where Gladion and Lillie have to team up to rescue a rare and endangered Pokemon. They might face various challenges along the way, like dealing with Team Skull. Another idea is a time - travel plot where they go back in time to learn more about their family's past and how it relates to the Pokemon world. Or perhaps a story where they are separated in a different dimension and have to find their way back to each other while making new Pokemon friends and allies.
One interesting plot idea could be Ash and Lillie going on a special mission together to find a rare and powerful Pokemon that has the ability to heal other Pokemon. They face many challenges along the way, like rough terrains and other trainers who also want to capture this Pokemon. Another could be a story where Lillie gets lost in an unknown part of the Alola region and Ash has to use all his skills and knowledge to find her. During this time, he discovers more about Lillie's past and the secrets she has been hiding.
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.
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.
Some plot ideas for this fan fiction could start with Lillie finding an ancient artifact that has the power to control certain Legendary Pokemon. This sets off a chain of events where she has to protect it from evil organizations. Another idea is that Lillie's Pokemon evolves in a completely unexpected way, and this new form has abilities that no one has ever seen before. This leads to her being in the spotlight as people try to figure out what's going on. Additionally, a plot where Lillie and the main character from Pokemon Sun are sent back in time to the origin of the Alola region and have to witness and even influence the events that shaped the Alola we know today would be very engaging.
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 interesting plot could be Lillie's journey to become a stronger trainer. She might face challenges and overcome her fears with the help of her pokemon. Another could be a love story between the main character and Lillie, as they travel through the Alola region together.
One interesting aspect could be Lillie's growth. In some fanfictions, she might have more in - depth interactions with Pokemon that are not shown as much in the game. For example, she could have a special bond with a certain Pokemon that helps her overcome her fears more quickly.
A lemon - obsessed scientist could be an interesting character. This scientist is researching the effects of lemons on Pokemon evolution. He might initially seem a bit crazy but actually has some valuable insights. He could be a bit of an antagonist at first, trying to use Lillie's connection to Pokemon to further his research without considering the well - being of the Pokemon. But later, he could become an ally when he realizes the importance of ethical research. Lillie would have to deal with his unpredictable behavior throughout the fanfiction.
