Another possible plotline could be that Evil Ash is on a quest to conquer a certain region. Serena, with her own Pokemon, decides to oppose him.

A common plotline is that they get injured while exploring a mysterious new region. Maybe they encounter a rare and powerful Pokemon that attacks them. Another is during a big competition where there's some sort of sabotage. For example, someone could have set a trap for them in the arena. And sometimes it's just a random accident like a landslide while they're on a mountain path.
One possible plotline could be Ash's discovery of his own latent legendary powers. Maybe he starts to exhibit abilities that are unique to legendary Pokemon, like controlling the weather or having an extraordinary bond with all types of Pokemon.
Well, clearly Ash and Serena are the main characters. Ash, in this case, is the 'evil' version, which is a departure from his usual good - natured self. Serena is likely to be the one who tries to bring back the old Ash or at least stop his evil deeds.
In the fanfiction, perhaps there's a plot where Ash has to save a legendary pokemon from an evil organization. He might use his experience and the trust of his other pokemon to rescue it.

A possible fanfiction plot could be that Ash, Serena, and May are invited to a mysterious island full of unknown Pokemon. They have to work together to survive and discover the secrets of the island. Ash's leadership, Serena's ability to communicate with Pokemon, and May's quick decision - making skills would be crucial.
One interesting plot could be Ash and Serena going on a journey together just the two of them. They face challenges that test their relationship and in the end, they realize their feelings for each other more deeply. For example, they might get lost in a mysterious forest and have to rely on each other to find their way out, which brings them closer.
A great storyline could be that Serena decides to start a new Pokemon performance group in Alola, and Ash helps her recruit members. They could travel around the Alola region, looking for Pokemon and trainers with special talents in performing. This would not only bring a new aspect to their relationship but also introduce new characters and Pokemon to the story.
Well, perhaps in a scenario where Serena is in danger and Ash saves her. The relief and pent - up emotions lead to a kiss. It shows how deep their bond has become through all their adventures together. This kind of situation is often used to heighten the drama and romance in fan - made stories.
