Another way these stories can end is with a new balance being created. Maybe the character is part human and part animal forever. This could be a result of a complex magic that couldn't be fully reversed. It shows how the character has grown and changed, and now exists in a new state that combines both her human and animal selves, bringing a unique perspective to both worlds.
Often, they end with the character being transformed back to their original form. For example, through finding a magic antidote or by the kindness of another magical being.
They often end with the transformed character fully accepting and loving their new identity. For example, they might find a new community that accepts them and they start a new life.
Often, they end with the character either fully accepting or rejecting their partial transformation. If they accept it, they might use it to their advantage and become a sort of protector or hero in their world. For example, a character who can partially transform into a bear might use their new strength to defend their village.
Often, they end with the character being transformed back to their original form. For example, they might find a magical item or perform a certain task that reverses the transformation.
One example could be a story where a young girl finds a magical amulet. When she touches it, she transforms into a beautiful swan. She then has to navigate the world of the swans while still having her human consciousness and dealing with the challenges of being in an animal's body.
Many inanimate transformation stories end with a sense of wonder and a new equilibrium. Say a rusty old key turns into a magic key that unlocks a hidden door to a wonderful land. The characters then explore this new land, and the story kind of settles into this new situation where the transformation has led to a new adventure or discovery.
Often, they start with the introduction of the character in their original state. For example, in 'Watership Down', we first meet the rabbits in their warren. Then, something forces them to transform or adapt, like the destruction of their home. This sets them on a journey where they encounter various challenges and meet other characters. Their animal forms influence how they face these challenges, like how rabbits might use their speed and burrowing skills.
Often, they end with the character being transformed back to their original form. This is a common and satisfying ending as it restores the normal state of things.
Often, they end with the authorities intervening. The animals are removed from the hoarder's property. For example, in the case of the cat hoarder, the cats were taken to animal shelters where they could receive proper medical treatment and care.
They provide a fictional space for people to understand the concept. By reading about the characters' experiences during transformation, readers can get a sense of the internal and external challenges that come with changing gender. For example, how a character feels when they start to notice physical changes in an mtf transformation story.
Protection is also a big theme. They usually transform to protect something, like the Earth or their friends. In 'Sailor Moon', Sailor Moon transforms to fight against the forces of evil that threaten the world. And the animal - like features in her transformation might symbolize certain qualities like agility (like a rabbit) that help her in battle.
