Iron Man: Extremis

Extremis is a six-issue Iron Man story arc written by Warren Ellis with art by Adi Granov and published by Marvel Comics. The arc first appears in Iron Man (vol. 4) #1-#6. "Extremis" profoundly redefines the status quo for Iron Man, introducing a new origin story for Iron Man, the first since the character's creation, and increasing the power of Iron Man's armor significantly.
