Transformation Fiction

Go To

Transformation Fiction is a genre of fiction depicting a transformation or shapeshifting of one form or another. Whether it's a willing transformation or not depends on the piece of fiction, as well as whenever it's reversible or not, and whether they can transform or shapeshift into more than one type of being. The transformation would most likely be depicted as a Bit-by-Bit Transformation, but this isn't required.


While a piece of Transformation Fiction might have some Author Appeal or be slanted towards specific Fanservice, transformation can also be used to explore such themes as gender roles, racism, feelings of isolation/not belonging, and the maturation process.

Types of transformation seen in Transformation Fiction include but are not limited to:

This genre is Older Than Dirt. Almost every world mythology has tales involving Baleful Polymorphs, Emergency Transformation, Transflormations, and Shapeshifters — the Youkai; The Fair Folk; Skin Walkers; the Norse, Greek, and Roman gods; the Djinn of the Middle East, the Coyote and Raven tales of Native American Lore and many more.


The transformation can be Played for Drama in a Beast and Beauty, Fish out of Water, or Freakiness Shame tale. Played For Fear with Transformation Horror or Played for Laughs or as An Aesop in a Trickster's tale. Transformations can begin The Hero's Journey and can have the story end either in a Downer Ending or a Bittersweet Ending, although examples of them ending with a Happy Ending also exist. Compare Henshin Hero (which is more about switching back and forth from a superpowered form). Compare Xenofiction (stories told from the viewpoint of a non-human-like character) See Transformation Causes for a list of possible ways one would transform or shapeshift into a different form within the story. See also Werewolf Works and Werebeast Works.

A Transformation Comic is a type of transformation fiction dealing with transformations within comics. May overlap with any trope in the Shapeshifting index.

As an important note, having a being who transforms or shapeshifts throughout the story doesn't mean the work's of this genre. In order to count, the transformation(s) have to be the focus of the story in some way.
