Age Regression

Stories in this category deal with characters starting at one age, then regressing in some way to a younger age. Most stories portray a physical regression, but mental, emotional, and other shifts related to age can happen as well. While a lot of stories are about regressing from an adult to a child, they can cover any range of ages.

Properties
In transgendered art and fiction, the protagonist frequently undergoes either psychological or physical regression, with neither being mutually exclusive. In the former, a male character may believe he has become a young female; plot devices often involve hypnosis, classical conditioning, amnesia or - less commonly - sexual roleplay.

Physical regression, by contrast, generally requires an actual transformation from adult to child. In this scenario, the regression may be the result of medical intervention, divine judgement, scientific breakthroughs, transmigration or any number of fictitious rejuvenation technologies.
