Well, in such a fanfiction, it could be really interesting. Serena has a romantic side towards Ash, and Misty has a long - standing connection with him. The story might focus on how they try to outdo each other in terms of getting Ash's attention. Maybe they'll compete in things like helping Ash catch Pokémon or just spending time with him. It all depends on the writer's take on their relationships.
Well, in Ash x Mirror Serena fanfiction, often there's a sense of the unexpected. Since Mirror Serena is a different version, she may have different personality traits compared to the original Serena. This can lead to unique interactions with Ash. For example, she might be more assertive or have different goals.
A possible storyline could be that Misty and Serena accidentally find out about each other's feelings for Ash. So, they start a friendly competition where they try to do things that would make Ash notice them more. For example, Serena might practice harder for her Pokémon performances, and Misty could train her Pokémon to be even stronger to impress Ash.
In this kind of fanfiction, it could be about a rivalry in high school. Ash and Dawn might be a team or a couple, and Serena is their rival. Maybe it's a battle of skills like Pokémon battles or a competition for popularity. For example, they could be competing in a school - wide Pokémon tournament, and Serena has some new strategies that Ash and Dawn need to counter.
Another fanfiction to check out is 'Mirror Serena's Journey with Ash'. This one starts with Mirror Serena being quite different from what we expect, but as she spends time with Ash, she begins to change and their relationship evolves in a really engaging way. It's a great read for fans of this pairing.
One possible scenario could be that in this high school fanfiction, Ash and Serena form a team to compete against Iris in a Pokémon battle tournament organized by the school. Ash's experience and Serena's elegance might create a unique synergy that gives them an edge, while Iris with her strong and wild Pokémon could pose a great challenge. Maybe there are also some romantic subplots between Ash and Serena as they battle side by side, and their relationship might grow deeper during this rivalry with Iris.
I think Serena is more popular in Ash fanfiction. Her character development in the anime was quite significant, especially in relation to Ash. In fanfictions, this can be taken further. Her determination to follow Ash and her own dreams simultaneously makes for great story material. While May was a great character, Serena's more recent and somewhat more complex relationship with Ash gives fanfiction writers more to work with, like exploring how they might reunite or continue their journey together in different scenarios.
One idea could be a friendly competition between Dawn and Serena over who can help Ash catch the most rare Pokémon in a new region. They might set different strategies and use their unique skills to outdo each other while still remaining friends.
They would probably be a bit shy at first. Ash being his usual energetic self but also respectful of Serena's space in the tent. Serena might be a bit nervous but also excited to be sharing such a close space with Ash.
The plot might revolve around a Pokémon sports day at high school. Ash and Serena join forces to take on Iris in a series of challenges. Maybe they compete in races where their Pokémon have to run or fly across the school grounds. Ash's Pikachu could be the star runner, while Serena's Pokémon might have some special abilities for the flying part. Iris, with her dragon - type Pokémon, could be a tough competitor. Their rivalry could be not just about winning but also about proving different Pokémon training methods are better.
