Making her comics debut in ACTION COMICS #252, from 1959, the Girl of Steel quickly became Superman's secret weapon in his battle for Truth, Justice and the American Way--and a key hero in the DC Universe. In these initial stories, Supergirl, like her cousin Superman a survivor of the planet Krypton, adjusts to life on Earth with her adoptive parents, the Danvers. The stories alternate between small town slice-of-life tales about boys who must be shown that magic can be real, Supergirl's own efforts to master her new powers, and time-traveling jaunts into the far future and past. Plus- How can Supergirl babysit a Superman who's been mysteriously transformed into an infant? These classic tales are now featured in SUPERGIRL- THE SILVER AGE VOL. 1! Collects stories from ACTION COMICS #252-284.
