Uberfic

Uberfic (short for Uber fanfic, UberXena, or simply Uber or Über) is a kind of alternative universe fan fiction in which characters or events are portrayed somewhat closely to original canon but usually in a different time period, many times featuring the ancestors, descendants or reincarnations of canon characters. The term originated in Xena: Warrior Princess fandom. This sort of story was used by the series itself, beginning with the second season episode "The Xena Scrolls".

Some consider the first uberfic in the XWP fandom to be the X-files crossover Warrior's Heart by Darkone that first appeared in February 1997.

A popular example of the genre are the characters Dar and Kerry that were first seen in Tropical Storm.
