J'onn was a reserve member of the Justice League prior to the destruction of Metropolis. He did not associate himself with the League when it became a worldwide police force, opting to support Batman and his endeavors with the Insurgency.

When Batman formed the Insurgency, J'onn did not immediately announce his presence; Batman wanted him to remain hidden until he knew who he could trust.

J'onn acted as a spy in the Watchtower and on several missions with Superman and Wonderwoman, including their discovery of Lex Luthor.

Bruce then devised a plan to kidnap Hawkgirl and replace her with J'onn. The plan worked, feeding information to Bruce for a long time. When J'onn, as Hawkgirl, teleported to the Batcave and saved Alfred's life from Batman's giant penny, Robin put the pieces together and deducted that J'onn was not Hawkgirl. Uncovered, J'onn hid elsewhere while Damian made his escape to tell the Justice League that Shiera was still being kidnapped.

Following the revelation of Bruce's identity to the world as Batman, J'onn posed as Batman while Bruce escaped far from the cave. He talked to the Justice League, whereupon Diana threatened him to stop his actions. In response, J'onn flies into the air and through a cloud, becoming intangible in the process. He knocks Green Lantern out of the air and confronts Superman. He shows Clark a vision of J'onn's exile from his home, where he was dominated by the White Martians and his children were taken from him. "You know this feeling," referencing Clark's loss of Lois, their baby, and Metropolis.

Diana then tries to interfere, but J'onn grows vines and snakes into her body, strangling her organs and body parts. She orders Clark to use his heat vision on her, seemingly killing J'onn in the process.

Possible Post-Regime Epilogue

Injustice Gods Among Us Vol 1 1 Textless

This section of history takes place in a timeline outside that of normal Injustice: Gods Among Us history. Information here does not reflect the true history of neither the Injustice: Gods Among Us universe nor the Injustice: The Regime universe, and should not be seen as relevant to future sequels or comic adaptations.

Martian Manhunter IGAU 0001

Banishing his friend and former teammate Superman to the Phantom Zone was difficult for J'onn J'onzz, but necessary. As the One Earth Regime had formed, J'onn, ever the outsider, had chosen to watch from a distance to bide his time. He assumed the form of an Atlantean, and served as royal archivist. Aquaman little suspected that his trusted subject's uncanny ability to gather news of the surface world was the result of telepathic powers.

When J'onn learned that heroes from a parallel dimension were aiding Batman's Insurgency, he assisted as well, leading rescue operations in Metropolis and Gotham after Superman's rampage. In the post Regime era, the Martian Manhunter continued to serve his adopted world, gathering the next generation of heroes to form a new Justice League.



  • Vulnerability to Fire: Martians are much more vulnerable to fire than the average Earth human. At times this has been portrayed as physical, psychological, or a combination of the two. The effect of this is to strip any Martian of their powers as they involuntarily lose control of their body.
