Immortal Iron Fist #21 (2008) Marvel comic book. Written by DUANE SWIERCZYNSKI, Pencils by TIMOTHY GREEN II, Cover by JUAN DOE. Danny Rand was not the first Immortal Iron Fist...and he won't be the last! The year - 3099. The place - a distant planet first colonized a millennium ago by the People's Republic of China. Now, a humanity oppressed by a totalitarian technological tyrant has just one hope for salvation - the kung-fu freedom-fighting of the Immortal Iron Fist! But his coming is nothing more than a prophecy and a silent prayer...and even if the Iron Fist does arrive, he must first defeat the most powerful weapon the evil robot empire has...Robo Fat-Cobra! Hot off the heels of Duane Swierczynski and Travel Foreman's rip-roaring "MORTAL IRON FIST" arc comes an all-new look at the future legacy of the Immortal Iron Fist...with a jaw-dropping cover by Juan Doe!
