By the mid-1970s, owing to the successful efforts of its new creative teams, the Legion of Super-Heroes began to share equal billing with its iconic member, Superboy. The new, racier Legion's popularity skyrocketed, setting the stage for more 30th century classics to come. This volume celebrates that legendary era of Legion history with 16 classic stories from SUPERBOY AND THE LEGION OF SUPER-HEROES #213-223 and KARATE KID #1, written by Cary Bates, Jim Shooter and Paul Levitz, with art by Mike Grell, Ric Estrada, Michael Nasser and others, and a cover by Grell. In addition, long-time Legion fan Mike Flynn contributes an introduction.
