Superman #21 (1988) by John Byrne kicks off "The Supergirl Saga," introducing a new, post-Crisis Supergirl who isn't Kara Zor-El but a mysterious, shapeshifting alien empowered by Lex Luthor, leading to confusion and conflict with Superman as she imitates Lana Lang and challenges his understanding of Kryptonian history and family, setting up a major storyline for the era.
This issue marks the debut of a reimagined Supergirl for the post-Crisis DC Universe, an alien entity rather than Superman's cousin, as Byrne wanted Superman to be the sole survivor of Krypton.
All comics come bagged and boarded
