After the final battle between God Emperor Doom and Mister Fantastic, Battleworld was destroyed, and this reality became a distorted portion of time and space. Due to this universe having been the epicenter of the rebirth of the Multiverse, in it abounded a substance known as Iso-8, which originated as a byproduct of creation itself.
The Elders of the Universe then staged a Contest of Champions for control of a concentrated ingot of Iso-8 known as the Iso-Sphere, until The Collector's champion, Maestro, secretly allied with The Grandmaster's champion, Punisher, ultimately defeating The Grandmaster and utilizing his portion of the Iso-Sphere to overcome The Collector as well. With the full power of the Iso-Sphere at his disposal, Maestro then banished the Elders from the universe while reforming Battleworld, so that he could assume the position of God-King of the Battlerealm.
