Saurian

Saurians are that are described as sapient reptiods who evolved from  blooded. They are depicted in movies and video games like Mortal Kombat, Star Fox, and even Star Trek.

Origins
A saurian in its most advanced evolutionary stage is depicted as a. Over millions of years of evolution, their will also evolve into, initially developing a form of psychic defense. This ability allows them to camouflage themselves, or enter into a chameleon like state. On Earth, this ability even allows them to occasionally walk among unbeknownst humans. Advanced species develop superior technology to enhance their cloaking abilities, even invisibility. However, the most highly advanced reptoids are the type that can walk between dimensions becoming visible and invisible at will, without the aid of technology. Reptoids of this nature are extremely rare. The progenitors of the Saurians are exactly this type of advanced reptoid. A loose term for their identification is, the Tiamatians. They came from what the call, the Lokas or Talas. Some of these reptoids may be depicted as.

Earth seeds
In, the Tiamatians seeded dinosaurs and Saurians on Earth, and quite possibly other worlds, for the open minded. The Saurians on Earth, evolved from who used their thumb spike as a tool or defense mechanism. proposed that this thumb was attached to a venom gland. Tweedie's theory is not supported by the mainstream, but it is interesting that venom does play an important role in the evolutionary process. It is not confirmed that all Saurians have this evolved ability, but some have been known to possess a powerful corrosive fluid that can easily burn through steel and most organic materials, including other Saurians who do not have a defense against this natural weapon.

Society
The Saurians on Earth used a matriarchal society that was so important to them that if one were to drift away from the influence of their matriarch, or a surrogate, they would slowly lose sanity, thereby losing parts or all of their psychokinesis abilities. The Saurians once thrived on the surface of Earth, but eventually relocated to the subterranean levels below, building vast cities that interconnect at key locations, such as the poles, and Mount Shasta.

Mortal Kombat
In Mortal Kombat, the Saurians are known as "Raptors" and "Zaterrians". They were eventually driven from their homeworld by a war waged between the Elder Gods, Raiden, and Shinnok. In an attempt to survive extinction they fled to the realm of Zaterra, where they thrived once more (although in the end this attempt at survival would prove futile). When Shao Kahn, the emperor of Outworld, invaded and merged his realm with that of Zaterra, the Saurians were seemingly driven to extinction. There are only two known survivors of the species: Reptile and Khameleon, although one could assume that Chameleon is one as well considering his similar abilities and name style.

Star Fox
In Star Fox, saurians live on "Dinosaur Planet" called Sauria. It is a large planet inhabited by multiple tribes of dinosaur denizens. The climate is as varied as that of Corneria, with lush green forests, traversable volcanoes, snowy mountains, and purple dusted mountains. The ruling tribes are the EarthWalkers and the CloudRunners. The CloudRunners and EarthWalkers are at odds.

Star Trek
In Star Trek, the Saurian race are spacefaring humanoid reptilianoid species who are members of the United Federation of Planets in the 23rd century. They are lizard-like humanoids with purple skin and bulging yellow eyes.
