Action 290 (July 1962) is another all red-kryptonite issue, but not as good as the previous one.
Superman and Krypto fly through a red kryptonite cloud in this Swan and Klein story, and wind up losing the invulnerability in half their bodies.
Superman does manage to pull off his normal super-feats, in more complex ways, to cover this loss of power. Lois Lane is hot on his trail, though, dragging Jimmy Olsen along with her, as she tries to find a way to exploit the situation and prove Clark is Superman.
Some backwards clothing, and a really uncomfortable position on the couch, are all that are needed to fool her again.
The Supergirl story, by Siegel and Mooney, is more interesting.
Phantom Girl presents Supergirl with a statue of herself for her birthday. The statue turns out to be made of red kryptonite. This is supposedly an accident. Really? Phantom Girl just happened to find a piece of red kryptonite and carved it into a statue of Supergirl? I think not.
At any rate, the red kryptonite has the effect of passing super-powers on to anyone Supergirl kisses. And as it’s her birthday, she planted kisses on her mom, Dick Malverne, and Jerro.
When Edna Danvers manifests super-speed, Linda figures out what is going on. She goes to check on Dick Malverne, who shows off his new abilities by taking her flying.
Jerro has also taken to the air, and the rivals wind up meeting. But they do not immediately begin fighting, as I was expecting them to do. Lois and Lana would be at each others throats by now. But the boys get along, and work together,until their powers wear off, leaving them in danger.
The Supergirl Emergency Squad have their debut, coming out of Kandor to rescue the two boys. Supergirl is just thrilled to have her own mini-army of devoted followers, and glad that the boys powers have worn off.
So you have to wonder, what was Phantom Girl up to? Coming from the future, she must have known the properties of this version of red kryptonite. Why give Brainiac 5’s rivals for Supergirl’s attention powers? Perhaps to show Supergirl that they cannot handle them well, unlike Brainiac 5?
