The Exo-Space, also known as the Neutral Zone, is the space found between realities,[5] beyond the Superflow,[2][6] where negative and positive matter coexist.[7] It is home to eldritch forms and predatory concepts,[2] and powerful matter called Neutronium.[8] The Neutral Zone is a "buffer zone" that leads to the Outside, beyond the Multiverse.[5][2][6][1]

The Brashears[]

It was discovered by the Blue Marvel, who kept exploring it after his son Kevin was left stranded there when the Brashears foiled Dr. Evald Skorpion's villianous plan to access the Neutral Zone and weaponize its Neutronium.[8] He initially believed the Exo-Space to be merely an alternate dimension.[9]

Adam's other son, Max Brashear also worked in finding a way to rescue Kevin. However, he failed to stabilize the portal and it had to be shut down.[8]

Some time later, Max peacefully reached out to his father to work together to free Kevin.[9] They managed to devise a solution, and used it to temporarily bring Kevin, now empowered by the Neutral Zone, to banish the powerful Beyond Corporation's agent. Kevin's return lasted a few seconds, but Blue Marvel set out to try to reach out again.[10]

The Ultimates[]

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 America Chavez had not closed it. This impressed the Blue Marvel and he welcomed her into the Ultimates.[5]

The border to the Outside

The Ultimates later ventured into Neutral Zone, after passing through deep space and the Superflow, in order to reach the Outside.[2] There, they met Conner Sims,[11] the Anti-Man, who was previously thought to be dead.[12] The Blue Marvel attacked his former friend but his son Kevin returned and convinced him to take Conner with them.[11]

The Sharra-IV, a Shi'ar monitoring station orbiting around and observing the Great K'ythri, a wormhole connected to the Exo-Space, was attacked by Thanos when he used the Exo-Space as his entry point back to existence.[13]

Conner Sims attempted to commit suicide by going to the Outside and passed the Neutral Zone along the way, but was saved by the Lifebringer Galactus.[6]

The Defenders[]

Eternity gathered the Defenders to investigate a threat from outside the Multiverse and orchestrated a series of events that would lead his selected crew into the Neutral Zone. In this "liminal space," he opened the way to the Outside.[1]
