Other Uses
Various comic stories, pre- and post-Crisis, have offered glimpses of possible futures assuming that one of the various incarnations of Supergirl would eventually change her codename to Superwoman upon reaching what she considered adulthood. One example is a 1980 issue of Superman Family, in which all the stories are set in the then- near future 1999 or 2000 (the timeframe is cited only as "the turn of the century") with the characters aged appropriately, including an older Linda Danvers (Kara Zor-El) who divides her time between her career as Superwoman and serving as governor of Florida.
Alternatively, some stories assume one of Superman's female descendants would assume the name "Superwoman", like his daughter Kara and great-granddaughter Lara from the Elseworlds series, Superman & Batman: Generations.
