It could be an adventure story where Ash and Misty, as mermaids, explore the underwater world of Pokémon. They might discover new Pokémon species that are unique to the underwater realm and have to face challenges like protecting their underwater home from some kind of threat.
Perhaps it's a romantic fanfiction. Ash and Misty, in their mermaid forms, could fall in love all over again in a different context. The underwater setting can add a lot of charm to their relationship, with beautiful coral reefs as their backdrop and dolphin - like Pokémon playing around them as they share their feelings.
You can try looking on fanfiction websites like FanFiction.net or Archive of Our Own. They have a large collection of fan - made stories, and you can simply search for 'Ash and Misty mermaid' in their search bars.
The story could be about their daughter's journey in the Pokémon world. Maybe she inherits Ash's love for adventure and Misty's strong will. She could start her own Pokémon journey, facing challenges and making new friends, just like her parents did.
Perhaps it occurs during a time of danger. They could be in a situation where they think they might not make it out alive. In that moment of fear and closeness, their emotions run high and they share a kiss. This would add a lot of drama and intensity to the fanfiction, as it would show how their relationship could be strengthened by such a life - threatening experience.
Well, in such a fanfiction, it could begin with Misty being the one to make the first move towards a romantic relationship. She might confess her love to Ash. From there, they would start to build a more intimate relationship. The fanfiction could include them traveling together again, but this time as a couple. They would face challenges as a couple, like dealing with jealous rivals or misunderstandings. But in the end, they would decide to get married. The wedding could be held in a beautiful location, like a Pokemon - filled forest or by a crystal - clear lake. And their Pokemon would play important roles in the ceremony, like Pikachu being the ring - bearer.
In some fanfics, Misty might be portrayed as betraying Ash for power. For example, if there is a powerful trainer who offers Misty a chance to become an even greater trainer, but at the cost of leaving Ash behind. She could be tempted by the allure of advanced training techniques or rare Pokémon that this new opportunity presents.
The fanfiction might start with the unexpected news of Misty being pregnant. Ash could be initially shocked but then overjoyed. As the baby grows, they could travel together as a family, with their baby making friends with different Pokémon along the way. It would be a heartwarming story of a Pokémon - loving family.
Well, their life would be full of adventures. They could travel around different regions together, with Misty showing her water - type Pokémon skills and Ash using his battle experience. They might also start a Pokémon training school in Pallet Town, teaching young trainers about Pokémon care and battle strategies.
Well, considering Ash's journey across different regions and Misty's connection to water Pokémon, the wedding could be by a large, beautiful lake. Ash and Misty would exchange vows with the sun setting in the background. All their friends from their travels, like Brock and Tracey, would be there. And there would be lots of Pokémon - water - type Pokémon creating a magical water display as they say 'I do'.
One possible plot could be that they are on a journey and stop at an inn. They end up sharing a bed due to limited accommodation. They start by being a bit shy but then have a deep conversation about their adventures, dreams, and how much they mean to each other as friends who have been through a lot.
It could be really cute. Maybe it would start with Ash and Misty finally realizing their feelings for each other and getting married. Then, they could discover they're going to have a baby. The fanfic might show them preparing for the baby's arrival, like getting a special Pokemon to be the baby's guardian.
