Green Martian (Barsoom)

The Green Martians are one of the predominant races of Barsoom. They are green-skinned monstrous people who stalk the dead sea bottoms of barsoom. They are intelligent and capable of organizing themselves into a society, but they are almost to a man all brutish and cruel.

Biology & Attire
The Green Martians are the largest of the Martian races, the males standing up to fifteen feet tall and the females up to twelve. They have green skin, small antennae-like ears just above the eyes, and large tusks. In the males these tusks extend upwards to the level of the eyes. The eyes themselves are large and wide-set, with snowy white sclera and blood red irises. Each eye is capable of moving independently of the other. Green women differ in the fact that their skin color is lighter, their tusks extend up to the level of their antennae, and they also have vestigial fingernails.Like all other Martian humanoids, they lay eggs; newly laid eggs are described as being the size of a goose egg, and the young take up to five years to hatch. The young are miniature replicas of the adults, standing 3 to 4 feet in height when hatched, with yellowish-green skin that darkens as they age. The most distinct trait of the species is their six limbs - two arms, two legs, and an intermediary set of limbs that can be used as arms or legs. Like most other Martian humanoids, the Green Martians go almost completely naked, wearing only a harness and jewelry.

History
The complete origin of the Green Martians is mostly unknown. They first appeared in the waning days of the White Martian races, when the oceans began to recede, and began raiding the Orovar and Lotharian cities, driving these once-great civilizations into increasingly remote regions. When the White races abandoned the cities, the Green hordes took over. Though they appear to have lacked the intelligence to make use of most of the ancient technology left behind, their size, brute strength, and abundance of limbs for many years prevented them from being driven out.

As time grew on, the Green hordes ran out of enemies and began to fight amongst themselves. They began to split into different hordes based on the kingdoms they occupied - the horde that occupied the ancient city of Thark began to call themselves Tharks, the horde that controlled Warhoon began to call themselves Warhoon, etc. The bitter rivalry between the Tharks and Warhoons led to brutal campaigns of genocide, which had the side-effect of reducing the Green populations to the extent that the emerging Red Martians finally managed to claim some of the major kingdoms like Helium, Dusar, Ptarth, and Amhor.
