The ISO-Sphere is a powerful artifact that is capable of rewriting reality and granting its wielder any wish.
The Collector has claimed that the Iso-Sphere grants its possessor enough power to rival gods.
In Earth-15513, the Iso-Sphere is the most potent form of the Neutronium in its Iso-8 form. The Elders of the Universe waged in a Contest of Champions for its possession, a game in which different individuals they abducted from across the Multiverse fought to the death of behalf of each Elder.
Near the end of the contest, only two contestants remained, Maestro and the Punisher, representing the Collector and the Grandmaster, respectively. As part of a secret scheme to acquire the entire power of the Iso-Sphere for himself, Maestro proposed the idea of a refined and new Contest of Champions, in which Maestro and the Punisher would act as summoners and choose several new players to play on each Elder's behalf.
With each battle the new players fought, the percentage of the Iso-Sphere each of the remaining two Elders possessed varied. When the Grandmaster found himself with only a sliver of the Iso-Sphere, Maestro attacked him and stole his portion, which still didn't rival in power the amount of Iso-Sphere the Collector possessed. However, 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 trumped the Collector's desire to possess the Iso-Sphere and acquired its entirety.
The Iso-Sphere was snatched from the Maestro by Outlaw when he was distracted fighting other contestants. Outlaw's desire to use the Iso-Sphere to return everyone to their normal lives and end the contest overpowered Maestro's, and the Iso-Sphere shattered as it teleported the contestants to wherever they wanted to be, and Maestro to a cell in the Collector's Museum.
