One common theme is Ash gaining new powers through the transformation. He might use these powers to overcome tough battles in the Pokémon world.
Another theme could be the relationship between Ash and his Pokémon changing. Since he has transformed into Absol, his Pokémon might react differently to him, and this can lead to some interesting character development and storylines. It could also explore how Ash adapts to his new form and the instincts that come with it. For example, Absol is known for its ability to sense disasters, so Ash in this form might have to deal with those premonitions and how it affects his journey.
Often, there's a theme of self - discovery. Ash might learn more about himself, his place in the Pokémon world, and his connection to different Pokémon species as a result of the transformation. It can also involve a struggle between his human self and the new Absol - like instincts, which can create internal conflict and drive the story forward.
One common theme is adventure. Since Ash is often on his Pokemon journey, the fanfictions might include Absol joining him on his adventures, and their relationship growing during those travels.
Another theme is the relationship with trainers. Sometimes, the transformation of Absol is linked to its bond with its trainer. A strong bond might trigger a positive transformation, while a broken bond could lead to a more chaotic or negative transformation.
One common theme is friendship. The transformation of Absol into an anthro form often leads to a deeper bond with Ash. They might go on adventures together and support each other, showing how friendship can transcend species boundaries even in a transformed state.
One common theme could be the beauty of Absol in a unique way. Maybe it's about how its appearance stands out in the Pokémon world. Another theme might be a relationship between Absol and a trainer, focusing on how the trainer discovers the beauty of Absol, not just physically but also in terms of its personality.
A common theme is the struggle for acceptance. When Ash transforms, other characters might react differently. Some may be afraid or skeptical, and Ash has to deal with not being recognized or trusted at first. Another is the theme of sacrifice. His transformation could be the result of sacrificing something important, like a deep bond with a particular Pokemon. And of course, there's the theme of heroism. Transformed Ash becomes a symbol of hope and is able to save the day in more epic ways than before.
One common theme is the loss of self. When Ash transforms in horror fanfiction, he might start to lose his identity as a trainer. For example, he could become more like the Pokemon he transforms into, forgetting his goals and friends. Another theme is the fear of the unknown. The transformation process itself is often mysterious and unpredictable, creating a sense of horror. Also, there can be themes related to being an outcast. Since his transformation is abnormal, Ash might be shunned by his friends or society in the fanfiction.
You can try searching on fanfiction platforms like FanFiction.net or Archive of Our Own. They usually have a wide variety of fanfictions including those related to Ash and Absol transformation.
Another theme could be the relationship between the female Absol and a trainer. This might involve themes of trust, growth, and friendship as they journey together through the Pokemon world. Maybe the trainer initially misunderstands the Absol due to its somewhat intimidating appearance, but they gradually form a deep bond.
Survival is also a theme. They could be in a situation where they have to rely on each other to survive in a harsh environment, like a post - apocalyptic world or a dangerous, unexplored territory.
I'm not sure specifically as it could be about many things. It might be a fan - made story related to a transformation involving Absol, which could be in the context of a Pokémon fanfic perhaps, where Absol undergoes some kind of change or transformation.
