God Emperor Doom's History
When the multiverse finally perished in the final incursion between Earth-616 and Earth-1610, Doom used the power of the Beyonders to salvage the remains of several realities and build a patchwork planet named Battleworld, which was ruled under his iron fist, with the help of Stephen Strange, who was Battleworld's sheriff. Molecule Man continued empowering God Emperor Doom, and remained hidden in a chamber. During the early days of this planet, Doom encountered an alternate version of the Fantastic Four, one in which Reed Richards didn't exist. Their Sue Storm fell in love with Victor, and they had two children, Franklin and Valeria.
As eight years went by, Doom and Strange managed to twist the memories of their inhabitants, to the point they would no longer remember what had existed before Battleworld. Even though he was an omnipotent ruler, Victor ultimately felt he was failing his duty as a god, he thought he wasn't capable of properly inspiring his people, and even though Battleworld was the perfect world he wanted, he considered himself its only flaw.
The relative monotony of Doom's reign was interrupted with the discovery of an empty vessel in the domain known as Utopolis, a life raft that had been built by the survivors of Earth-1610, the villainous Maker and the Cabal. The vessel kept them in suspended animation for the eight years that passed, and had allowed them to survive the end of the multiverse and end up on Battleworld.
Sheriff Strange recognized the design of the raft, which was that of a similar vessel he had found three years earlier and had kept hidden in his Isle of Agamotto. When Strange investigated the vessel of his proprietary, he freed its occupants, the survivors of Earth-616, among which were Mr. Fantastic, Namor and Black Panther.
After being informed of the nature of Battleworld and its ruler, the survivors of Earth-616 helped Sheriff Strange confront the Maker and the Cabal, who had been finally pinned down by Battleworld's police force, the Thor Corps. Doom remained unwilling to take part in the conflict, until he saw Mr. Fantastic in the scene, which is when he immediately teleported to Utopolis, and stopped the fray, demanding the newcomers to recognize his authority. To prevent Doom from prejudicially acting upon the interlopers, Stephen used his magic to teleport them away. Following the disappearance of the Cabal and the heroes from Earth-616, Doom confronted Strange for disobeying him, and ultimately killed him after Stephen accused him of being afraid of Richards.
Doom later commanded Valeria and the department of science of Battleworld, the Foundation, to find the interlopers, pinning Strange's murder on them. Three weeks later, Battleworld was in disarray, with disorder having escalated into open rebellion in several domains, with somebody called "the Prophet" forming an army against Doom. The Prophet, who was later revealed to be none other than the Cabal's Maximus the Mad, and his army marched forward to Castle Doom. Some of Doom's allies started fighting against him, namely the Thor Corps, who had been convinced to fight against their god by the Thor survivor of Earth-616.
When he decided to step into the fight, Doom was confronted by Black Panther and Namor, with the former having acquired an Infinity Gauntlet from Sheriff Strange's sanctuary. After a battle that took them through the different planes of reality, Doom bested Black Panther, but he soon realized the fight was a distraction. He teleported to Molecule Man's chamber, which had been found by Mister Fantastic. The Molecule Man partially stripped Doom from his power in order to allow a fair fight. During the furious confrontation, Doom accused Richards of believing he could've done better had he had Doom's power, and when Reed conceded he did, so did Doom. On the grounds that both agreed, Molecule Man gave Doom's power to Reed, destroying Battleworld in the process.
With the power he had received from Molecule Man, and with help from his revived family, Mister Fantastic began to restore the Multiverse, including Earth-616. When he returned Victor to Latveria, Reed cured Doom of his scars.
