Immortal Iron Fist #20 (2008) Marvel comic book. Written by DUANE SWIERCZYNSKI, Pencils & Cover by TRAVEL FOREMAN. Danny Rand's life--it all comes down to this! The job title may be "Immortal Iron Fist," but the individuals who take on that mantle are anything but. And after his 33rd birthday, Danny found out exactly why--when he came face to face with the Ch'i-Lin, a malevolent force that kills every Iron Fist at age 33. But why? And how was his predecessor, the long-lived Orson Randall, able to escape it? Danny better figure something out fast, or he'll be trading in his costume for a green-and-yellow body bag! It's the pulse-pounding conclusion of THE MORTAL IRON FIST, by Duane Swierczynski (CABLE) and Travel Foreman (ARES)!
