Action Comics #252 irl is mostly known for teaming up with Barbara Gordon when working with the Bat Family, especially after their iconic “Girl’s Night Out” episode from the animated New Batman Adventures. But one of Kara’s best team ups was with another Batgirl – Stephanie Brown.
In this issue Supergirl comes to visit Stephanie at Gotham University for some R&R. But, of course, Stephanie and Kara are superheroes so this average trip to the movies turns intos the story where it all began in 1959.
Supergirl crash lands on Earth, and Superman finds out he is not the only Kryptonian still alive – he has a cousin from his home planet.
Superman quickly brings Kara to an orphanage to live, and gives her a secret identity – Linda Lee. Kara tries to adjust to her new life on Earth as she balances her life secretly as Supergirl and orphan, Linda Lee.
Kara’s origin is only a few pages long, but the issue jam packs a lot of Kara’s story in these limited confines. It’s a good set up to show the hero Supergirl would become and what stories you could expect from future Action Comics issues at that time.
