Superman's greatest feats are not his strength or ability to fly at ridiculous speeds but his tendency to put other people's lives before his own. While he has moved Earths, contained singularities, and even pushed the moon into its rightful place using magnetic fields, the Man of Steel is best known for his acts of kindness. So when his archnemesis Lex Luthor comes to him demanding that he find a cure for his terminal disease, Superman has no choice but to comply. Written by Mark Waid with artwork from Bryan Hitch and Kevin Nowlan, colors by David Baron, and lettering from Richard Starkings and Tyler Smith of Comicraft, Superman: The Last Days of Lex Luthor #1 from DC Black Label shows how intertwined Clark and Lex's lives are.
