J'onn J'onzz is the Martian Manhunter, one of the last survivors of the planet Mars who came to Earth in search of justice and peace.
Mars was a living world, populated by a race of humanoids divided by skin color. However, one day the populace received a psychic warning, which the government perceived as a threat and recruited several of its people, including a young J'onn J'onzz to investigate. While on their mission, the government agent Ma'alefa'ak unveiled a double-cross, killing all of the subjects except J'onzz and then used their blood for a magic ritual that super-empowered J'onn - permanently, against his will.
Hunting Ma'alefa'ak, J'onn discovered a monster - the cause of the psychic warning that had sent him on the mission in the first place. Taking the shape of J'onn J'onzz's daughter, the monster explained that it was the embodiment of the dying Martian biosphere, trying to warn the populace to help it. However, the embodiment decreed that they were unworthy, and Mars and the Martians died, throwing J'onn to Earth, where he attempted to become a hero once again.
