After being sealed away in Amenth alongside the First Horsemen, Genesis and the other mutants decided to make Arrako their home and build towers to protect them from the threat of the Daemons. She along with the High Council of Arakko ruled over Arakko for centuries, while fending off the Daemons' attacks. However, at some point in time the High Mutant Prophet Idyll foresaw the inevitable defeat of Arakko by the hands of their at told the Council about this. At first Genesis laughed at this claim and threatened Idyll to decapitate him, but then decided to listen to him and she, alongside her army went on a years old crusade to end Arakko's threat for good. Their battles became legends on Arakko and their victories were celebrated. She and her army eventually faced their fellow mutant White Sword, and his One Hundred Champions, who saw Genesis and her army as equal to his enemies and showed them no mercy, forcing Genesis and what was left from her army to retreat to Arakko.
Eventually, Isca send a message to Genesis from Amenth's dark god and leader of the Daemons, Annihilation who challenged her to a combat for the ultimate victory. Genesis accepted the challenge and went to the Hall of Annihilation where Annihilation and her army awaited her. The two fought fiercely, and eventually Genesis defeated the dark god which proved her to be strong enough to wear it. However, she refused to become one with it, leading to the Daemons to imprison her, while they assaulted Arakko. As Genesis was unable to stand the massacre, she finally decided to wear the Golden Helm causing Arakko to defected to the side of Amenth.After confronting Saturnyne in the Starlight Citadel, Apocalypse would encounter his wife once more, as she revealed herself to be the latest to wear the mask of Annihilation. After that, the two met again under the Starlight Citadel where she told her husband the full true story of what had happened to them while on Amenth.
Annihilation then observed behind the scenes as the tournament went on. Following the battle between White Sword and Gorgon, the scores for Arakko and Krakoa were even, and both Annihilation and Apocalypse prepared to fight. During their battle, Genesis without the Golden Helm, seemed to have the upper hand as she managed to destroy her husband's sword, but suddenly Apocalypse grabbed her sword, the Twilight Sword, shoved it to her stomach. She begged Apocalypse to kill her, but he refused leaving Annihilation to take control of Genesis and summon almost all of the Amenthian forces to Otherworld, intending to conquer Krakoa for good. However, as the war went on the Champions of Krakoa were joined by the reassembled X-Men and Captain Britain Corps and eventually the Vescora. As the war was seemingly turning to Krakoa's favor, Apocalypse was able to remove the Golden Helm off Genesis' head, causing it to possess Apocalypse. However, unlike Genesis, Apocalypse was able overcome the Helm's influence and used it to make the Amenthian forces to surrender. After that, Saturnyne turned the Golden Helm into a less corrupting staff and gifted it Genesis, while Apocalypse switched places with Arakko, returning the long lost island back to Earth, and then Apocalypse reunited with his family and began governing Amenth together.
