Love and affection are common themes. Since there's a kiss involved, it often explores the budding or established relationship between Ash and Mallow. Another theme could be discovery, like the characters discovering new feelings for each other through the kiss.
One common theme is probably the development of their relationship. The kiss could be a turning point in their story within the fanfiction. It might also touch on themes of friendship - turned - love. Maybe they were friends before and the kiss changes the dynamic completely. Additionally, themes of passion and longing could be present, as the kiss is a physical manifestation of their deeper emotions.
Another theme is self - discovery. Ash Mallow usually learns more about himself and his powers during the course of the fanfiction. For example, in some stories, he realizes his true potential when faced with great challenges.
One common theme is friendship. Since Ash and Mallow are friends in the Pokemon universe, many fanfictions explore the depth of their friendship, like how they support each other during tough battles or in their personal growth.
Another theme is the development of their relationship. It often starts from being friends or comrades in the Pokemon journey and then slowly blossoms into something more romantic. Writers like to explore how they gradually realize their feelings for each other through different events, like helping each other out in tough battles or sharing a special moment during a festival in the Pokemon world.
One common theme could be friendship. Ash and Mallow might be shown having a deep and meaningful friendship that develops into something more. Another theme could be adventure, with them going on quests or exploring new places together.
A common plotline could be that Ash discovers Mallow has betrayed him in some form, perhaps by sharing a secret he entrusted to her. This then leads to a rift in their relationship and Ash has to decide whether to forgive her or not.
Nature and exploration are also common themes. Given that Pokemon are often found in various natural habitats, fanfictions might have Mallow exploring different terrains, from lush forests to vast oceans. This exploration also ties into her discovery of new pokemon species and learning about their behaviors.
Given that this is a rather unusual concept, if it exists, the themes could be quite unique. There could be a focus on how the pregnancy affects the mallow's role in the story's setting. For example, if it's in a fantasy world, perhaps the mallow's pregnancy has some sort of magical or prophetic significance. Or in a more mundane setting, it could be about the mallow adjusting to a new life with a baby on the way, including things like preparing a nursery or dealing with career changes if relevant in the fictional context.
A common theme is the exploration of their individual growth within the group. For instance, Lillie might overcome her shyness with the help of Ash and Mallow. Also, there are fanfictions that focus on their teamwork against powerful opponents. They might combine their different skills and Pokemon to defeat a difficult enemy. It's interesting to see how different authors play with these elements.
Often, the theme of unspoken feelings is present. May and Ash might be secretly in love for a long time but too shy or focused on their Pokémon goals to act on it. Then, finally, there's a moment of realization and the kiss. It's also common for the fanfiction to explore how their friends and Pokémon react to this new development in their relationship.
One common theme is the build - up of their relationship over time. The fanfictions often show how Ash and May grow closer through their adventures together, leading to that special moment of a kiss.
