One possible scenario could be that they are preparing for a Pokemon-themed party. Ash might choose to dress up as his favorite powerful Pokemon like Charizard, with a cool red and orange costume and wings. Lillie could go for a more elegant look, perhaps dressing as a fairy - type Pokemon like Sylveon, with a pink and white frilly dress. They would have a great time showing off their outfits to their Pokemon friends.
It could be that they are just having a fun day at the Pokemon Center. Ash finds some old clothes and starts to create a wacky costume, like a combination of different Pokemon parts. Lillie giggles at his creation and then shows him her own dress - up idea. She has made a dress similar to the one she wore when she first met Snowy, but with some added sparkles and ribbons to make it more festive.
Dressing up can be a form of self - expression. If Ash dresses in a more sophisticated way, Lillie might see a different side of him. Maybe she'll start to see him as more than just a Pokemon trainer. And for Ash, if Lillie dresses up in a more adventurous style, he could be inspired by her new look. This mutual influence through their dress - up can bring them closer together, whether it's in a friendship way or potentially a romantic way as the story progresses.
One possible scenario is that she is at a Pokémon - centered party. There are some friendly Pokémon playing around, and one of them accidentally tickles her feet while chasing another Pokémon. This causes her to giggle and creates a fun and lively atmosphere.
For Ash, he could be dressed in a formal Kanto trainer's uniform with a shiny red cape, symbolizing his journey's success. Lillie could wear a beautiful white and blue dress inspired by Alola's ocean, with a crown of flowers on her head, like a princess of the region.
Ash is impulsive and always up for a challenge. This could lead him to choose a difficult - to - make but very cool - looking costume, like a Mega Lucario. He would spend hours trying to get the details right, like the blue and yellow markings. Lillie, who is a bit shy but has a creative side, might choose a less - known but very cute Pokemon like Stufful. She would make a plush - like dress with big ears and a little tail, and it would reflect her sweet and quiet personality.
In certain fanfiction stories, Ash could faint as a result of a psychological shock. Imagine if he discovers that one of his beloved Pokemon has been mind - controlled by an evil organization. The sheer horror and disbelief could be so overwhelming that he faints. Additionally, he might be caught in a powerful psychic attack from a very strong psychic - type Pokemon that not only weakens his physical state but also his mental state, leading to his fainting.
One possible scenario could be that Ash betrays May for a powerful Pokemon. Maybe he gets offered a super rare and strong Pokemon but has to cut ties with May to get it. Another could be that May betrays Ash because she is influenced by a rival trainer who convinces her that Ash is holding her back from reaching her true potential as a Pokemon trainer.
Perhaps in the fanfiction, there's a threat to the Pokemon world. Ash and May team up to face it. During their adventure, they rely on each other, share their hopes and fears. This mutual understanding and support lead them to a realization of their love for one another. And in the end, they plan to get married to build a future together in the Pokemon world.
One possible scenario could be that all their Pokémon friends are part of the wedding. Pikachu might be the ring - bearer, with little ribbons on its ears. Another scenario is that they have the wedding on a beach near a Pokémon Center. Ash could be wearing a traditional tuxedo, and Misty in a beautiful white dress with a water - type Pokémon motif.
One possible scenario could be that Ash and Serena are at a Pokemon festival. The music starts and they begin to dance. Ash, who is usually more focused on Pokemon battles, is a bit clumsy at first but Serena guides him. As they dance, their Pokemon join in the fun, creating a lively and heartwarming scene.
In many Pokemon fanfictions, the idea of Ash and Lillie getting married is quite interesting. Some fanfictions might focus on their adventures together that lead to their deepening relationship and ultimately marriage. It could start with them traveling through different regions, facing challenges side by side, and gradually realizing their feelings for each other. This would be a really sweet and heart - warming story for Pokemon fans who support this pairing.
