It was discovered by Blue Marvel, who kept exploring it after his son Kevin was left stranded there when the Brashears foiled the plan of a villain to use a portal to the Exo-Space to tear the dimension apart due to the energy feedback. He initially believed the Exo-Space to be merely an alternate dimension.
Some time later, Max peacefully reached out his father to work together to free Kevin. They managed to devise a solution, and used it to temporarily bring Kevin, now empowered by the Neutral Zone, to defeat a being from the powerful Beyond Corporation. Kevin's return lasted a few seconds, but Blue Marvel set out to try to reach out again.
The arrival of a mysterious being into the universe caused a breach in the fabric of reality, creating a tear the size of a planet which could have potentially torn the galaxy apart if Ms. America of the Ultimates hadn't closed it.
