Fanfiction about Ash and Lillie's Betrayal: What Could the Storyline Be?

First, develop strong characters. Understand Ash and Lillie's personalities well. Ash is known for his determination and kindness, while Lillie has her own insecurities and growth throughout the series. Then, create a believable reason for the betrayal. It should make sense within the context of the Pokémon world. For example, it could be related to a misunderstanding about a powerful Pokémon's proper care.

In this fanfiction, the betrayal might start with Mew stealing a powerful and unique Pokemon from Ash. Mew, being a rare and powerful Pokemon itself, could have a complex motive. Maybe it wants to prove its superiority by taking something precious from Ash. Ash would be heartbroken and angry. He would then embark on a journey to get his Pokemon back, facing many challenges along the way and ultimately having a confrontation with Mew where he tries to understand why it betrayed him and if there's any way to fix their relationship.

I'm not sure specifically as there could be many different takes in fanfiction. It might involve scenarios where Ash and Lillie break someone's trust, perhaps in the context of their adventures or relationships within the fan - created story.

In a fanfiction, perhaps Clair betrays Ash because she believes he's not a worthy trainer. She might think that Ash's methods are too haphazard and that he's endangering the Pokemon world. So, she teams up with an organization that wants to control the Pokemon trainers, leaving Ash feeling abandoned and betrayed. This could lead to Ash having to prove himself even more to the Pokemon community and also having to face Clair in a big showdown later on.

In such a fanfiction, perhaps Ash betrays his friends for power. He might be lured by an evil organization with the promise of rare Pokémon or ultimate power, and in the process, turns his back on Pikachu and the others.

One plot twist could be that a powerful Pokémon villain tries to stop the wedding to use their combined power for evil. Another could be that a long - lost relative of either Ash or Lillie shows up with a secret that shakes their relationship. Maybe a prophecy is revealed that their union will have unforeseen consequences for the Pokémon world.

The plot could involve a threat to Alola. Ash and Lillie, now in love and getting married, have to put their wedding plans on hold to save the region. Along the way, they discover that their love gives them extra strength. They defeat the threat together and then have a grand wedding celebration, which is attended by Pokemon trainers from all over the world.

One possible plot could be that Ash finally realizes his true feelings for Lillie after many adventures together. They decide to get married on Alola's most beautiful beach. All their Pokémon friends help in preparing for the wedding, like Pikachu arranging the flowers and Snowy helping Lillie with her dress.

One possible plot could be that Ash and Lillie decide to travel the world together after getting married. They visit different regions, encounter new Pokémon, and share their knowledge with local trainers. Along the way, they face challenges like natural disasters that threaten Pokémon habitats, and they work together to save the Pokémon and the environment.

One possibility is that Ash's adventures would change. He might not be able to go on long journeys as easily with a baby at home. So he could focus more on local adventures or teaching his child about Pokémon.
