History
The planet Mars, nicknamed Ma'aleca'andra by the Martians, was home to a powerful and hostile race known as the Burning. These beings reproduced through asexual means and possessed vast pyrokinetic powers and abilities. In addition to these traits, they made extensive plans of intergalactic conquest, proving to be an immense threat to the Martians, who were residents of Mars. Worrying that these beings would ruin untold and soon to be lives and species, the Guardians of the Universe interfered in the scenario and defeated the race and instilled in Martians, the residents of Mars, a deep fear of fire and a weakness that would extend in the bloodline of Martians for years and centuries. Martians were also split into two separate races; the White Martians and the Green Martians. One of these many Martians of the two races that were produced from the split of Martians as a whole was J'onn J'onzz, who was transported to Earth in the 20th century.

It would take some time until J'onn J'onzz learned, much to his dismay and surprise, that he was transported from Mars to Earth not only through space, but time as well and that his planet had dissolved to a state of extinction, as no Martians were present on the surface of the red planet.
