Myah-Zeitzho
Also known as Greys/Grays, Myah-Zeitzho are the most common Hathan to be found on Earth. Originally coming to earth in the 1920s when their planet began to die, a series of agreements were created between their people and the U.N. of the time to allow them to slowly ship their people into the states, however when rumors and stories began to run rampant in the 1980s, certain parts were changed, but still they were allowed to come. It is believed their people were housed in secret facilities across the world, and apart of the agreement was for them to bring pieces of their world, from soil, to plants, to animals, with them. Unfortunately when the 1990s came and video became a house hold ability, this agreement was once again changed, instead of just a bit of an altercation, it was fully cancelled this time, as the leaders of the U.N. didn't believe the world was ready to learn the secrets of space.
While it is unknown what exactly happened to their home and those who couldn't get off the dying world, the Myag-Zeitzho who stayed here went through several horrible events, ranging from experimentation to torture, to even living a life of luxury as an assistant to the Emperor of Cananadia. It wasn't until the 2030s, when Zeke Zerdin made his infamous 'Final Moments' speech, that alien life was truly accepted by the world. It was during this time that the million and a half Zeits were allowed to leave, and even then wasn't until the 2080s before they were allowed full freedom from governments, unfortunately this was short lived as the world went into a war during it's next decade.
Now only a couple thousand still survive, however thankfully due to the many experiments done to their initial people, cross breeding between them and humans have become possible, as well as the creation of clones using the machines found in the S.M.I.L.E. bunkers.
There are two particular forms of Myah-Zeitzho; Miel and Kauh. Miel
Typically shorter, standing at an average of 4'8", the Miel Myah-Zeitzho have no noses, no noticeable outer ears, and only have a small orifice for a mouth with teeth somewhat similar to ours but coming to more of a point. They have no hair, elongated bodies with small chests, and lack almost all muscular definition with a visible skeletal structure. Their legs are shorter and jointed differently from humans, and their arms are longer. In proportion to their body, their heads are unusually large, and hold a very round shape, and their skin has an almost latex, silk like smoothness. Another thing different about them from humans is that they wield only three fingers. The Miel are unusually nice and often try to make friends with everyone and everything, but don't let that lead you to thinking they won't get angry, as when they get offended, they have been known to leave a fairly vicious bite. Kauh Very similar in appearance to their Miel cousins, the Kauh Myah-Zeitzho have a more triangular shaped head, and average a taller height of 5'1", with more proportionate legs to their bodies. Their skin is typically more loose and wrinkled. Unlike the Miel, they have five fingers. Almost all Kauh seem to have a love for squash, and give off a much ruder attitude than the Miel.
