Комикс World War Hulk Aftersmash: Warbound Vol #4

Within the dome surrounding Gammaworld, Hiroim has discovered that his Old Power is what is powering the dome. Concluding the only way for the dome to fall is through his death, he tries to convince Korg to end his life. When Korg refuses, Hiroim attacks, trying to force his ally to slay him in combat. Korg refuses to do so because he doesn't care about the humans who are trapped within the dome. However, Hiroim demonstrates how powerful the Old Power has become by smashing Korg's head open and then using his power to heal the damage. He warns his ally that he will not be able to control the Old Power for much longer. He then strikes Korg again, send the Kronan landing before a group of people searching for rescue. Korg warns Hiroim to stay back because of the humans, but the Shadow Priest is not swayed.
