The Invincible Iron Man #19

In this pivotal 2007 issue of The Invincible Iron Man, the Hulk returns to Earth in a stone spaceship, demanding retribution from the heroes who once outwitted him—threatening planetary destruction if he isn’t confronted. Iron Man, suited up in a custom Hulkbuster variant, takes to the skies to face the jade giant in a battle that could decide the fate of the world. Written by Christos Gage and illustrated by Butch Guice, with colors by Dean White and letters by VC's Joe Caramagna, the cover by Gerald Parel captures the intensity of the clash.
