In honor of the 100th birthday of Jack "The King" Kirby, some of today's greatest comics creators are throwing down a one-of-a-kind challenge to one another to create the most breathtaking, mind-blowing story the world has ever known. This is The Kamandi Challenge! Kamandi, Jack Kirby's beloved post-apocalyptic Last Boy on Earth, fights for his survival and the fate of all humankind in a world overrun by intelligent tigers, giant robot leopards, edible plant people and even more wonders. But this is no ordinary comics story. Each all-star creative team leaves Kamandi in a death-defying cliffhanger, and it's up to the next storytellers to pick up the gauntlet and figure out how Kamandi will survive! The result is a wild comics ride that's worthy of the King himself! Take up the challenge and see how a combination of comics legends and today's best creators-including Tom King (Batman), Neal Adams (Green Lantern/Green Arrow), James Tynion IV (Detective Comics), Bill Willingham (Fables), Amanda Conner and Jimmy Palmiotti (Harley Quinn), Ivan Reis (Justice League), Walter Simonson (Orion) and more-set out the ultimate challenge for their fellow creators!
