When the Multiverse was restored by Reed Richards, Earth-15513 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 arrived from their native universe and decided to stage a Contest of Champions for control of a concentrated ingot of Iso-8 known as the Iso-Sphere, with the Grandmaster and the Collector fighting for control, with the Grandmaster's team, being dubbed the Yellow Team. With each battle waged between the two teams, the winner Elder would acquire a percentage of the other's portion of the Iso-Sphere.
As contestants entered and left the game, the Collector remained with most of the Iso-Sphere, while the Grandmaster was left with a sliver, that made him barely powerful. During a final all-or-nothing match for the Iso-Sphere, Maestro and Punisher betrayed the people they had summoned and took them down. Maestro subsequently teleported to Grandmaster's HQ, and managed to defeat him due to the Grandmaster barely posessing any of the Iso-Sphere's power. The two portions of the Iso-Sphere desired to be with each other, prevented only by their owner's will. In a battle of minds, Maestro overtrumped the Collector's desire to possess the Iso-Sphere and acquired its entirety.
With entire control over the Iso-Sphere, Maestro casted out the Collector and the Grandmaster from the Battlerealm. Together with the Punisher of 2099, they imprisoned the Red and Yellow Teams and attempted to kill them one by one.
