A special, HULK-sized issue commemorating 100 issues of gamma-irradiated goodness with two big stories: Planet Hulk, Allegiance, Part 1: Is he the Sakaarson, destined to save the planet from its greatest enemies, or the Worldbreaker, the legendary destroyer of everything? The HULK continues his epic story on Planet Sakaar. In this issue, the HULK and Caiera the Oldstrong lead their warriors in an all-out battle against the horrifying Spikes. But even with the Hulk growing stronger, how can he and his warriors prevail against an enemy that consumes and possesses everything it touches? Featuring another shocking development in the story of Miek - and further hints about the identity of the Sakaarson - and the Worldbreaker. Plus, a 12-page back-up featuring the return of one of HULK's greatest artists, Gary Frank, as someone discovers that the Illuminati were responsible for sending the Hulk into space! Also reprints Incredible Hulk (vol. 1) #152 and #300!
