Martian (The Fate of the Poseidonia)

Martians are a sapient humanoid species from the planet Mars.

Biology
Martians physically resemble Humans, although their chests and shoulders are more well-developed, making the limbs appear thinner in comparison. Their skin is red and coppery, with a strange texture that feels like a dry sponge to the touch. Their eyes glow in the dark with a faint phosphorescence. Most noticeably, they have long white feathers covering their heads, arms and shoulders. These feathers can fold to cover their upper bodies like a shawl, or stand erect and spread out like a peacock's tail. Like Humans, Martians are a dioecious species with male and female individuals.

Culture and society
Martians don't wear clothes.
