Mars

Mars is the 4th planet closest to the Sun, and the second-smallest planet in the Solar System, being larger than only Mercury. It is a close neighbor to Earth and Teria.

Biology
Mars is often referred to as the "Red Planet", due to the effect of the iron oxide prevalent on Mars's surface, which gives it a reddish appearance distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, with surface features reminiscent of the impact craters of the Moon and the valleys, deserts and polar ice caps of Earth.

The days and seasons are comparable to those of Earth, because the rotational period as well as the tilt of the rotational axis relative to the ecliptic plane are similar. Mars is the site of Olympus Mons, the largest volcano and highest known mountain on any planet in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. While not comprised of Oxygen, the atmosphere on Mars is habitable, as it has been the home of its locals for generations.

Martian humanoids are rather unique when compared to other extraterrestrial races. Martians have violet skin, pointed ears that seem to point out in two different directions, and inverted eyes where the iris is white and the sclera is a different color. Interestingly, they also possess fangs reminiscent of "Vampires", which wouldn't been too far from the truth considering their culture. Martians suck fluids from their fangs, including blood, for nutrients, they need protective clothing when out in the sunlight, they possess no reflection when passing by a mirrored surface, and they lack any type of heart in their biology. The latter may also explain why they drink blood, since there is no heart to pump it through their bodies. Unlike traditional vampires however, they cannot shape-shift, they can be killed by normal means, and they aren't undead.

Martians don't live on a normal life-cycle like most beings, instead being "reset" after they "die". When a Martian reaches old age, their biological clock reverses, and they begin aging backwards, until they become an infant, in which the clock resets back to normal again. This never-ending cycle means that while Martians can age, it is unknown how old any of them are. They also retain all of their memories and intelligence when the cycle begins its first reversal, with Senialism being considered a illness for their kind.

Martians are a mostly all-female race (Though they don't refer to themselves as male or female), as they have evolved beyond the point of needing males to reproduce. Instead, they have two distinct genders; The Kudlak, who are Martians with the male reproductive system, as well as a few other traits, and the Kresnik, who are mostly similar to your typical female humanoid. It is extremely rare for males to be born, and even then, the offspring of a male Martian has a 0.01% chance of being male. If and when a male Martian is born, they are not outcastes, but are usually used as wet-nurses for the young.

Martians are extremely technologically advanced, and have visited other planets many times with their starships. As seen with their visits to Earth, they are sometimes viewed as hostile, due to their abduction of humans, however, this is done so that the people they bring to Mars can share their culture with the planet. Martians are a very inclusive culture, despite their harsh appearance, and hope to one day break down the borders between worlds and unite all cultures in harmony.

History
Martians have made contact with Earth multiple times throughout history, such as in 1947 when the male Martian Vega had crash-landed on Earth's Roswell, New Mexico, and began using his vampiric powers over the humans that lived there. Eventually, he was tracked down by the Martian Grand Republic's Army, as they shared with humanity their knowledge on how to seal Vega away. With the help of Anastasia Verum Nativiallum, Vega was entombed deep underground at Area 51, and as thanks, the Martians gave humanity some of their technologic knowledge, so long as they promised to never speak of their encounter.

Martians would still be seen here and there, inviting random people to go live on Mars, leaving crop circles in their departure.

Trivia

 * The Martian culture is very reminiscent of the Gerudo from The Legend of Zelda series, with Vega being comparative to Ganondorf due to him being the only male of his kind to be born in years.
