J'onn J'onzz is the last of the Green Martians. After arriving on Earth, J'onn adopted the alias of John Jones and became the superhero known as Martian Manhunter.


Justice League: Doom

Martian Manhunter assisted the Justice League in fighting the Royal Flush Gang. He used his mental powers to scan the minds of each member of the gang, but none of them knew the origin of the device.

Later, Martian Manhunter (in his human identity of John Jones) is celebrating his birthday with his colleagues from the police force. He receives a soda from a mysterious woman (who is actually Ma'alefa'ak in disguise). The drink is laced with magnesium carbonate, which is disruptive to Martian biology and leaves the Manhunter struggling to maintain his form while sweating out the highly flammable magnesium. Ma'alefa'ak uses a lighter to set his enemy on fire (Martian Manhunter's only weakness) leaving him to constantly burn for weeks or longer without the possibility to extinguish the flames, even when he goes into the nearby ocean. Batman provides Cyborg and Wonder Woman with aluminum oxide that when injected into the Martian by Wonder Woman, neutralizes the magnesium.

The Justice League arrived in time to save Superman. Cyborg cut his flesh, while Martian Manhunter took out the Kryptonite Bullet by shape-shifting his fingers.

In the Hall of Doom, Martian Manhunter defeated Ma'alefa'ak when the Justice League attacked the Legion of Doom. He and the other members of the Justice League barely manage to save Earth from Vandal Savage's scheme to orchestrate an apocalyptic cataclysm with a powerful solar flare.

He attended Batman's membership trial in the Watchtower.
