A lot of fanfictions also focus on Serena's growth as a character. For instance, how she becomes a stronger trainer or overcomes her insecurities with Ash's support. And sometimes, there are alternate universe stories where their relationship or their Pokemon journeys take a completely different turn.
A frequent theme is the support they give each other. Serena is always there to cheer Ash on in battles, and Ash helps Serena become more confident in her own abilities. Another theme is the idea of first love, as it's often portrayed as a pure and innocent feeling in these fanfictions.
Adventure is a major theme as well. They are all on Pokemon - catching adventures, and fanfictions often take them on new and exciting quests. Maybe they discover a new and rare Pokemon species or explore an uncharted region. These adventures not only test their skills as trainers but also strengthen their bonds with each other.
Growth and self - discovery are also themes. Through the act of kissing Ash, Serena may be seen as taking a step forward in her own personal growth. She is being bold and expressing her true feelings, which can be a form of self - discovery for her character. For Ash, it might also be a moment of realizing his own emotional development and how Serena has become an important part of his life.
Some fanfictions like to play with the idea of alternate universes. For example, what if Ash and Serena met in a completely different setting? Or what if their roles were reversed in some way? These alternate universe concepts can lead to really interesting and unique stories that still revolve around their relationship.
One common theme could be jealousy. Maybe Serena is jealous of Ash's attention to his Pokemon or other friends. Another theme might be competition. She could hate Ash because she sees him as a rival in the Pokemon world. Also, it could be due to misunderstandings. Ash might do something that Serena misinterprets and that causes her to dislike him.
One common theme is love and relationship development. It often shows how Serena and Ash's feelings for each other grow over time. Another theme could be adventure. The kiss might happen in the middle of an exciting Pokemon adventure. And of course, there's the theme of friendship evolving into something more.
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 common theme is their adventures together. Even in a relationship - focused fanfic, they might still be on Pokemon - related quests. Another is the development of their feelings for each other over time, showing how they gradually fall in love.
Adventure is also a big theme. In the Pokemon world, they go on various adventures, and fanfictions expand on these. For example, they might encounter rare Pokemon or face new and powerful trainers. Also, the theme of self - discovery is present. Serena may discover more about herself through her relationship with Ash, and vice versa. In some fanfictions, they also deal with the theme of sacrifice, like sacrificing personal goals for the sake of their friendship or the greater good in the Pokemon world.
