The Incredible Hulk #156

In "Holocaust at the Heart of the Atom!", the Hulk arrives on Jarella's world with Bruce Banner’s mind intact, only to find the city of K'ai in ruins and his beloved Jarella captured by the traitorous Lord Visis. With Banner’s intellect guiding him, he rallies the people in rebellion—until Visis allies with the deadly assassin Krylar, whose weapon forces the Hulk to confront his own darkest fears. Written by Archie Goodwin and illustrated by Herb Trimpe, with cover art by Trimpe, this 1972 Marvel classic delivers a mind-bending clash of identities, where the green giant must face the monstrous version of himself—while the line between hero and beast blurs.
