Planet of Origin: Mars
The Martians are short green skinned humanoids with a large head, wide eyes, pointy ears and a pair on antenna coming out of the top of their head. They developed an advanced civilisation capable of advanced space travel a long time ago when their planet was still able to sustain life. Some still survive deep below the surface but most have left their homeworld to wonder the cosmos, actively looking for a new home on whihc they could start anew.
Men of Mars action figures where commercialised in the sixties. Their story was told at the back of their blisterpack:
From below the surface of the dying planet Mars, the descendants of a once great race live on. Above them the majestic cities have long since crumbled and the vast canals lie buried beneath a silent sea of rust red sands. With time and water running out, Alpha 7 and other members of the Martian Armada travel the galaxy in search of another suitable planet to make their own. Their frequent reconnaissance missions and landings on our Earth have given rise to what most Earth men consider "wild stories" of "flying saucers" and "little green men".
