“The Cage of Doom!”

Superman trapped behind bars surrounded by suited figures spraying Kryptonite is a chilling sight, and this June 1969 issue of Action Comics makes the Man of Steel look genuinely vulnerable — his anguished plea to "finish me off fast" printed right on the cover for maximum dramatic impact. "The Cage of Doom!" promises exactly what it delivers visually: a desperate, weakened Superman at the mercy of cold, calculating captors. With cover art penciled by Curt Swan and inked by Neal Adams, this is a striking piece of late-Silver Age DC work that holds up beautifully.

At a regular meeting of the Legion of Super-Heroes, the Legionnaires lose control of their powers. Urthlo arrives and announces that he now controls the Legionnaires' powers and there is nothing they can do about it. But Saturn Girl comes up with a serum to temporarily cure Mon-El and immunize him against lead, and Superboy releases him from the Phantom Zone to knock out Urthlo, who turns out to be an automaton created by Lex Luthor sent into the future to destroy the Legion.
