Following countless incursions across every reality, the Multiverse was destroyed. Doctor Doom and Doctor Strange were confronting the beings responsible of this, the Beyonders, at the same time the final incursion was taking place between Earth-616 and Earth-1610.[1]

After having acquired omnipotent abilities, Doctor Doom was capable of creating an entire new planet from the remnants of incursion points between collapsing worlds, that new planet was Battleworld.[2] All the remains of these realities are known as domains, most have the ability to interact with each other, but it is not encouraged. Only three domains (consisting of the Deadlands, Perfection, and New Xandar) are separated from the rest by a giant wall named the Shield, simply for the fact that all three contain threats that if loosed would destroy the other domains.[3] Due to the Shield's importance, attacking or damaging the Shield, even if by accident, will lead to automatic exile to the wall to guard it.[4]

In Battleworld, Doom is praised as a deity. The right hand to Doom's religion is the Law, and its left hand is the Foundation, focused on discovery and science.[3] Eight years have passed since the creation of Battleworld, and its inhabitants no longer have memory of the worlds they lived in prior to Battleworld, and the now believe they have always lived on it.[2] Each domain of Battleworld is ruled by a baron or baroness. The borders of each kingdom are clearly defined, and travel between different domains is discouraged as it requires special dispensation from the local baron. The Thor Corps are Battleworld's police force, and are under direct command by Doom.
