The Multiversal War caused by Kang the Conqueror, in Avengers: The Kang Dynasty, will boost the incursions across the universes, which will be destroying the multiverse. The universes will start colliding and destroying each others. Galactus will interfere, consuming an Earth from each incursion to prevent the end of the universes involved in it. The final incursion, between the 616 Universe and the Ultimate Universe, will seem to destroy the entire multiverse with the destruction of both universes. The heroes from each universe will fight against each others and try to destroy each others' planets, but, it will not work. Before the colliding of both universes, the last Kang stole Galactus' power and created a new planet with the main locations from the whole multiverse, where he rules everything. Doom will want to take Kang's place as ruler of this new planet and will kill him, becoming the new ruler of the planet, as God Emperor Doom. To prevent the heroes from taking him away of the throne, he will erase everyone's memories, so they can't remember about their lives before the creation of this new world. The heroes, without their memories from their past home, Earth, will have to defeat Doom and restore the multiverse.
