Kryptonite is gone, but the Man of Steel's troubles have just begun in this collection of pivotal Superman stories from the 1970s! DC Finest presents comprehensive collections of the most in-demand and celebrated periods in DC Comics history, spanning genres, characters, and eras! Everyone knows Superman's major weakness- Kryptonite. But what happens when that's taken off the board, as a scientific experiment turns all the kryptonite on Earth to iron? Originally published in 1971, "Kryptonite Nevermore" turned the Man of Steel's status quo on its head, as his powers slowly begin to fade and a doppelg nger Superman arrives on the scene with strange powers of its own-and any contact between the two might result in the destruction of the planet! Along with "Kryptonite Nevermore," DC Finest- Superman- Kryptonite Nevermore includes further Bronze Age adventures by comics legends including Dennis O'Neil, Curt Swan, Cary Bates, and Len Wein! This volume collects stories from Action Comics #393-406; Superman #233-238, #240-246.
