Jack Kirby reinvented the superhero genre with his sprawling saga of the Fourth World--a bold storytelling vision that was decades ahead of its time. In honor of this extraordinary talent's centennial, DC Comics is proud to re-present the groundbreaking work of the King of Comics in a brand-new series of trade paperback editions collecting his classic DC titles in all their four-color glory! After walking away from a seemingly un-survivable plane crash, test pilot Ace Morgan, mountain climber Red Ryan, heavyweight boxing champ Rocky Davis and underwater explorer Prof Haley make a pact to continue defying death and seeking out mystery around the world. Their motto is "Dare Anything," and their assignments are the most unusual and incredible tasks ever encountered! There is no danger that they fear, or risk that they will not accept! They call themselves...the Challengers of the Unknown!

Discover some of comics' most daring writing and dynamic art--and thrill to the imaginative power of one of the medium's greatest masters--in CHALLENGERS OF THE UNKNOWN BY JACK KIRBY, collecting all of the King's stories from SHOWCASE #6-7 and 11-12 and CHALLENGERS OF THE UNKNOWN #1-8, accompanied by illuminating essays from former DC editor Paul Kupperberg and acclaimed Kirby historian John Morrow.
