Perry White gets the starring role in Action 278 (July 1961), in a story by Coleman, Swan and Kaye.
Perry sees an unusual plant outside his house. Having less common sense than one might expect, he picks a fruit from the plant and eats it, and promptly gains super-powers.
He adopts the identity of Masterman, but wonders if kryptonite will have any effect on him. Jimmy Olsen happens to be photographing the four known forms of kryptonite at this time, for a story Lois Lane is doing for the Daily Planet colour supplement.
Perry does fight crime as Masterman, but has more fun toying with the Planet staff. Still, the scene as he and Clark both find reasons to get away and change costumes is fun.
We then discover that Perry White is actually possessed by some alien plant life. See what happens when you eat random plants?
Superman and Perry White battle it out, Superman wearing the kryptonite-proof armor he devised against Luthor. But it’s Supergirl who saves the day, killing the plant possessing Perry by using white kryptonite, which only kills plant life.
There are very few white kryptonite stories, which makes it easy to label this one the best.
A good day turns very bad for Supergirl in this story by Siegel and Mooney.
Superman announces to Supergirl that, once he and Krypto return from an outer space mission, he will reveal her identity to the world. Superman has even made a tape showing her how this will play out – which is enough to tell you that it absolutely will not.
A cloud of kryptonite dust encircles the Earth, and Supergirl takes refuse underwater, with Lori Lemaris and Jerro.
After she saves a ship, people assume that it is Superman hiding under the water, and she performs a series of impressive feats, requested of Superman, all without leaving the ocean.
But as the story reaches its end, and Superman returns, Supergirl discovers that her powers have suddenly and inexplicably vanished. Superman has no idea what to do to bring them back, so he just sends her back to the orphanage.
Linda is left, confused, but still wearing her wig to bed.
