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 a biological transformation from adult to child. In this scenario, the regression may be the result of medical intervention, paranormal forces, scientific breakthroughs, transmigration or any number of fictitious rejuvenation technologies.
