Origin
An ancient race of chaotic and warlike beings the Burning Martians were perceived as a threat by the Guardians of the Universe.  Opposed to eradicating an entire race, the Oans saw potential in the Martians and genetically manipulated them to be vulnerable to the very force which drove their chaotic impulses, fire.

Suppressed of their chaotic impulses Martians then became known for their creative works, culture and dedication to justice and peace.

Eventually Martians were rendered practically extinct by a psychic virus which exposed their collective minds to chaos and consumed them in an uncontrollable flame.

The only known survivor J'onn J'onzz wandered the vast Martian desserts in shock for what may have been years or a millennium, until he was teleported to Earth by Professor Erdel, who was attempting to create an interstellar communications device.
