Action 285 (Feb. 62) marks the first time an issue has been devoted to one story, as Jerry Siegel and Jim Mooney have Superman finally reveal Supergirl’s existence to the world.
Linda’s adoptive parents, Fred and Edna Danvers, go over the edge of a bridge, and she reveals her powers while saving them. She is worried, as Superman told her to wait until his announcement, but Superman is forgiving. Good thing. Was she supposed to let them die?
Finally, the big moment arrives. Superman does a world-wide broadcast, introducing his cousin, and explaining her origin. Lori Lemaris and Jerro watch from Atlantis. Luthor is shown listening to this all on the radio, but does not comment about the mysterious Supergirl her had encountered in earlier issues.
Superman then heads out for a space mission, leaving the Earth in Supergirl’s hands. A mysterious menace, appearing as huge legs, starts tromping around, and JFK himself requests Supergirl’s help. She is at another fair with Dick Malverne, in her guise as Linda Danvers, and leaves him trapped in a maze to answer the president’s call as Supergirl.
The weird invading legs prove more than she can handle by herself, but she knows where to go for help. Or rather, when.
Heading to the 30th century, she heads to see the Legion. Cosmic Boy, Lightning Lad and Saturn Girl are pleased to see her, but it’s Brainiac 5 who proves helpful, giving her a weapon to use against the creature.
In gratitude, Supergirl is invited to the White House, where she meets not only JFK, but also the vice-president, LBJ, and Kennedy’s wife, JKO. Ok, so she wasn’t “O” yet. It fits the pattern.
