NA'VIS / PANDORANS / ALPHA CENTAURIANS

Planet of Origign: Pandora, a lush, Earth-like moon of the planet Polyphemus, in the Alpha Centauri system. Pandora itself has two moons. It was briefly colonised by humans in the 22th century but soon abandonned after an all-out revolt of the natives in 2154.
The Na’vis are a paleolithic species of blue skinned sapient humanoids with feline characteristics standing around 3 meters high. Their civilisationj is based on harmony with their ecosystem under a tribal structure. They live in large Hometrees and worship a mother goddess called Eywa. The Na'vis have tails whihc can be used as organic interface to bond with other lifeforms of the planet.

LAMETALIANS / RAMETALIANS

Planet of Origin: LaMetal. 
For millenias, the planet Lametall orbited the dark sun Ra. Ra followed an extremely large elliptical orbit which completed a revolution around the Sun in a 1,000 year period. Its orbit brought it, after a long journey in the far reaches of the outer solar system through the system's ecosphere. As far as it can be traced, by a capcrice of celestial mechanics, Ra was always hidden by Lametal from Earth's point of view. 
Circa 1999, the planet passed nearer to the Earth than it ever did before. Its atmosphere extended like a tail and fused with Earth’s atmosphere. This phenomenon, called the “Atmospheric Bridge” was short lived as  the “bridge” collapsed and disappeared 48 hours after LaMetal had started to move away from Earth. Their proximity to the Sun then slingshut Lametal and Ra out of the Solar system, heading toward the Andromeda galaxy.
Lametal is a planet with an air pressure, gravity, and atmospheric components which are roughly the same as Earth’s. However, it is much bigger. Observations vary as to its exact size. Some sources talk of a diameter of 109,404 km -about nine times Earth’s size- while other observations gave it only three times the size of the Earth. Those discrepencies in observations might be the result of visual distorsion caused by Ra's gravity well. It is known to be hollow with a moon-size core at its center. Its speed of rotation is 48 hours 22 minutes 43 seconds. 
The surface of the planet is usually covered by a thick layer of ice with a maximum extent of 3,000 meters. It is a bitterly cold world with a surface temperature of -280°C. 
During its time in the Solar System, each time it was coming near enough to the Sun, the ice melted, seas were born and cities buried underneath the ice began to appear, among them, the capital, Miyu City. The planet then knew a brief summer before its orbit brought it back toward the colder outer solar system. As it did, ice began to cover the planet again, starting at its poles and moving toward the equator.
After its departure from the Solar System, an orbital artificial sun was enginneered. It lasted  a thousand years before dying out. Then began the mechanisation of Lametal's population to ensure they could carry on in the depths of interstellar space. A civil insued, culminating with the destruction of the planet's outer shell. Luckily this happened as the planet was entering Euphrates, a binary star system locked in a fixed position halfway between the Milky Way and the Andromeda Galaxy. the inner core on which survivors had found shelter soon stabilised around Heavy Melder, one of the system's planet and became its moon.

Lametalians are humanoids looking much like Earth's humans but have much longer lifespans. They used to put themselves in hibernation while their planet was in the outer solar system, awakening only during their spring, as the planet was entering the inner system. At each passage of their world in the inner solar sytem, they had sent emissaries to Earth and had their planet not left the Solar System, they planned upon resettling on it. After its departure toward Andromeda. A plan was put in place to gradually transform the whole population into cyborgs in order for them to be able to survive in the intersideral void. When the planet's core put itself into Heavy Melder's orbit, the organics stayed while the mechanized ones continued toward Andromeda where they established themselves. 
It should be noted, as Lametal presumably gave birth to at least to a viable ecosystem and maybe a intelligent life (although it is dubious that human looking lifeforms would develop in parallel on both Earth and Lametal without any common origin whatsoever) that the planet was most probably in a much stabler orbit around the sun at one point, most presumably in the inner solar system, from which it has been torn at some point in the past.
It should also be noted that it took about a thousand years for the wandering Lametal to journey the 1,3 million light years separating the Solar System from the Euphrates star system which is halfway from the Milky Way to the Andromeda Galaxy; something that is physically impossible unless the planet was travelling faster than the speed of light or using shortcuts from point A to point B.
The two aforementionned points may be related to the presence of the black sun Ra in the vicinity of Lametal.

NOO

The Noo is a consciousness that developed just after the Big Bang during Plank Time and encompassed all the universe until is was sealed outside of it by the laws of physics. At the dawn of the 4th Millenium AD a scientific expedition journeyed to the Hourglass Nebula and discovered the gate of Yedar, a passage leading to the dimension where Noo was bannished. The scientists were possessed by the Noo, which enabled it to interact with our universe. Its ultimate goal is to fully return to our universe by reclaiming a part of its original body-in this case, the Earth itself. The possessed warped the planet into an alternate dimension using a Density Serial Cannon. The space pirate Harlock tricked the Noo into shooting its ship the Arcadia with the weapon, allowing him to meet it on its own ground and restore the Earth.
Noo's influence on our dimension lies in creating fear in sentient beings and thereby enslaving their wills and driving them against one another.

MONGOVIANS

Planet of Origin: Mongo, a rogue planet that passed through our solar system in 1933. Mongo is an inhospitable planet, with various extreme climate zones. Travelers to Mongo must pass through a "Death Zone" on the way, described as being "a zone devoid of any force". Mongo has at least two recognised moons, one of them being the planetoid Lunita. Mongo is approximately one of the diameter of earth but has a gravitational density that is only slightly less. It is a relatively young world with towering mountains not yet worn smooth by time and many areas of volcanic activity. Its vegetation is still limited to isolated areas of botanical giants.
Mongovians are humanoid looking much like Earht humans, with some subspecies having some morphological particularities such as lionmen and hawkmen.
In 1933, the mongovians were living under the control of a dictator, Emperor Ming. The people of Mongo had progressed scientifically beyond Earth. According to Ming, "the reason for our success is that we possess none of the human traits of kindness, mercy or pity! We are coldly scientific and ruthless!" The capital of Mongo is Minog City, also known as Nascent City. The main currency is the gold mingol. The area around the Emperor's palace is desolate and devoid of vegetation. Giant dragons live in the nearby caves. Other vicious animals of Mongo include monkey men, orangopoids and white-striped, bear-like animals.
The oceans of Mongo are home to giant sea life, including eels, sharks, water dragons and octosaks.
The planet is socially and geographically divided in several realms and the major ones are:
* Arboria is a forest principality governed by Prince Barin
* Frigia, a frozen kingdom ruled by Barin's cousin, Queen Fria,
* Coralia is an underwater kingdom beneath the Sea of Mystery. It is located east of Arboria and is ruled by Queen Undina,
* The Land of the Lion Men also borders the Sea of Mystery, and is ruled by King Jugrid and Prince Thun,
* The Magnetic Mountains are located east of the Land of the Lion Men and became the base of operations for Ming, after he was deposed
* The Sky City of the Hawk Men is located north of the Magnetic Mountains, and the leader of this realm is King Vultan,
* Tropica is a continent of forests. It is directly east of the Sky City. Queen Desira rules Tropica.
* The Fire Lands are located on the east coast of Tropica.

It also remains unknowns if they themsleves developed space faring technology or if they inherited it from their predecessors .

The insectoids made a desperate attempt to invade Earth in the 1970ies, disgused as humans and using the alien monsters Gigan and King Ghidorah they controled via technoloigcal means but their attempt was thwarted by the earth mutant monsters Godzilla and Anguirus. They later formed a deal with the seatopian human subculture living under the earth and showed them how to control the Gigan cyborg but with as disastrous results. The exact nature of their deal remains unknown.

GALMANS / GAMILAS / GAMILONS / ISCANDARIANS

Planet of Origin: Galman, distant of about 20 000 light years from Earth,
The Galmans are a humanoid species looking much like blue skin humans which developed an advanced interstellar technology a long time ago near the Milky Way's core.
At their height, they had expanded throughout the Galaxy and the Magellanic Clouds. However, as the Galman Empire waned, they lost control of their territories and were reduced to a few scant planets near their devastated homeworld. When the Bolar Union rose in power, they overtook Galman space and subjected it to severe living conditions. Of the scattered colonies outside the Milky Way, only the ones estalished on the twin planets of Gamilas / Iscandar managed to survive and prosper.
Circa 2200, Dessler, its leader, saved the Galman from complete destruction by freeing Galman from the grip of the Bolars. The Galman-Gamilas expanded into the Core region, the sagitarius and Orion arms. Their independance war from the Bolar Union resulted in the destruction of more than ten worlds, with the Bolar’s Planet Berth being the first casualty. Both sides used Planet-Destroying Missiles and Warp Missiles. Galman was laid waste by the arrival of the black galaxy phenomenon circa 2205.

It can produce further water to break through barriers and locks, and blast high-pressure sprays from their mouths and arms. The infected hosts show parched, cracked mouths, blackened teeth, and, after a while, faded blue eyes.

ANCIENTS / LANTEANS / ATLANTEANS / ANCESTORS / ALTERANS / ANQUEETAS

Planet of Origin: unknown in another galaxy
The Ancients are an advanced humanoid race who developed an intergalactic civilisation millions ago and eventually ascended to a state of pure energy on a "higher plane" of existence. They are best known as the builders of the Stargates networks found in the Milky Way and Pegasus galaxy.
Millions of years ago, a philosophical division emerged among them. Some grew more and more fervent in their religious belief, while others adopted a more scientific and rational outlook. Ultimately, the two groups split apart and began to oppose each other. The religious ones, aka the Ori, decided to destroy the non-believers who, rather than to fight them, left for what they called Avalon, the Milky Way.
There, they built an impressive empire, a vast network of stargates linking all their colonies and sent ships to spread Stargates to other galaxies. Among the planets they settled was Earth. As the planet's original Stargate in Antarctica was the oldest gate ever encountered, Earth was probably one of their more important worlds and the departure point of their stargate spreading ships. Eventually, they were afflicted with a plague tailored by the Ori. Most fled. Those who remained in the Milky Way galaxy either ascended or died out.
Those who fled to the Pegasus Galaxy settled on a planet they named 'Lantea'. Finding Pegasus devoid of sentient life, they seeded it with humans and Stargates. At some point they encountered a leech-like organism called the 'Iratus bug', which possessed impressive healing and immunological capabilities. Through feeding on humans, this organism absorbed genetic information from them and eventually evolved into the vampire-like Wraith.
The Wraith developed into an advanced but violent hive society while avoiding the attention of the Ancients until they felt their number big enough to confront them. Despite the Ancients' technological superiority, the Wraith overwhelmed them. The Ancients fled back to the Milky Way throught the Antarctica Stargates. Some stayed on Earth, spreading out to distant lands and helping to populate them, Others departed the planet, to live out their days on other worlds and allied themselves with the Nox, the Furlings and the Asgard. The remainder chose isolation in which to meditate and seek enlightenment. This would eventually lead to a spiritual ascension for some.
After their ascension, the ancients continued to oppose their former nemesis, the Ori, who had also reached Enlightenment. Although the two factions were deadlocked in strength, until, in 2007, a superweapon designed by the ancients was used by humans to destroy the Ori.

The Talosians were an aged, cerebral, sentient, humanoid species who were once a technologically advanced culture but a nuclear holocaust left their planet virtually uninhabitable and killed most of the species. The survivors of the nuclear war congregated in underground dwellings, where they became dependent on their mental ability to create stunningly real illusions, an ability that had been developed by their ancestors. As their mental powers grew, they lost the ability to use the technology left behind by their ancestors. The Talosians found that life using illusion was addictive, almost like a human developing a physical and psychological dependence on narcotics. They became bored with the content of the illusions which they had. Their dependence upon these illusions for mental stimuli caused the Talosians to begin capturing space travelers to use as the living basis for their illusions.

In the ensuing battle, these tiny but vicious criminals were stomped, and shot into extinction. The Zanti then sent a message of thanks to have done a task they could not do as their moral code prohibited them from killing their own kind.

FURRY ALIENS

The Furry aliens are a sexuate small (about 2 feet tall) humanoid species who developed a space faring civilisation and a technology that allows them to enlarge themselves to human size. Three indiivduals of the species briefly came to Earth in 1989 and absorbed american culture by watching ten minutes of television.

FACULTY PARASITES

The only known contact between humanity and the parasites happened in 1998 in Herrington, Ohio when a colony of the species tries dot take over a highschool by infection and infiltration. How and from where did they arrive remains unknown.
They appeared as small aquatic creatures that remained in a 'hibernative' state when on land. However, once infesting a human body or within water, the parasite became very active. Their small 'teeth' were capable of cutting human flesh. It sprouted tentacle-like fins around its form to move around its environment which also were perhaps used to 'fuse' with the host. Hosts infected were nearly incapable of being distinguished from non-infected hosts but the parasites were vulnerable to certain drug compounds inhaled through the nostrils which hurt them greatly. Once inside the host, the tentacles would link to the hosts body extensively. They granted increased strength and the hosts were capable of extending some of these tentacles outside the body into the form of tongues. The hosts were also remarkably preserved by the parasites and even decapitation did not kill them or the host, with the limb chopped off being reconnected. They were also capable of sprouting tentacles to move across its environment.
The queen or mother organism organism was actually human sized and able to shape shift between its normal form and that of its host which it seemed to have completely sbsorbed. The mother organism possessed many tentacles that were very strong and was capable of 'spitting' out its 'offspring' to infect new hosts. As the queen and its offspring were linked, its death would destroy the race without any harm to the hosts.

PUPPET MASTERS

The Puppet Masters are sentient stingray shaped exo-parasites which has somehow developed or most probably acquired space travel technology. Their forms are aerodynamic allowing them to glide through the air and use their tendril-like tongues, that can shoot out and pierce rocks, to aid them in movement. They could wrap their bodies and form a ball like shape where it would hibernate until a host would approach. They can reproduce without partners and transmit their genetic memory to their offspring.
Once arriving on a planet, Puppet Masters attempt to infiltrate the indigenous society. The initial infectees attempt to behave normally and trick new hosts into being infected by other parasites. This process of infiltration and implantation continue until the parasites dominate the environment.
Infection requires the parasites to attach themselves to the back of the host where a tongue-like tendril comes out the the creature's mouth and drill into the neck and two suckers take control of the host's nervous system. Once implanted by the parasite, the host serves as the creatures puppet and benefits from improved strength due to a stimulation of the adrenaline gland. They are also capable of taking far more punishment and damage from outside attacks then a normal human. Should the host be trapped or wounded, the parasite can abandon it and fly away. While the parasites work on a collective goal, they are individualistic and do not possess a hive-mind. Information is shared either verbally or chemically through 'feelers' on the back of the parasite which connect to the feelers of another parasite.
They are vulnerable to neurological diseases as their bodies were dominated by neural tissue.
Note: Apart from their shape, They are somewhat similar to the Goa'uld of SG-1.

TWILO-ITES / TWILOITES

Planet of Origin: Twilo
The Twilo-ites were the product of a nightmare experienced by comedy writer Rob Petrie (played by Dick Van Dyke) after he watched a late show thriller about aliens from outer space. In his dream Rob discovers that he is the last earthling who has not yet been possessed by aliens from the planet Twilo. The Twilo-ites had eyes in the back of their head, ate walnuts, and spoke with a British accent. They subdued earthlings by exposing them to the chemical Absorbitron. The Twilo-ite's leader Kolak took the form of Danny Thomas, and eloquent man dressed in bowler hat and cane who happened to be billed as the weekly guest star on "The Alan Brady Show." As Rob returned to the safety of his home, he opened his front entry closet only to find his wife, Laura (Mary Tyler Moore) inside lying ontop of thousands of walnuts (the favorite food of Twilo-ites). As Rob's nightmare climaxed, Kolak and all those possessed by him encircled him. But just then, Rob woke up.

VERMICIOUS KNIDS

Planet of Origin: Vermes (18427000000 miles from Earth)
Green-brown, with slimy skin and large eyes, at rest, It looks like “an enormous egg balanced on its pointed end. It was as tall as a big boy and wider than the fattest man. The greenish-brown had a shiny wetish appearcance andthere were wrinkles in it. About three quarter up, in the widest part, there were two large round eyes as big as a teacup. These eyes were white, but each had a brilliant red pupil in the center.”
“the Vermicious knid can turn itself into any shape it wants. It has no bones. Its body is really one huge muslce, enormously strong, but very stretchy and sqwishy, like a mixture of rubber and putty with steel wires inisde. Normally, it is egg shaped but it can just easily give itself two legs like a human of four legs like a horse. It can become as round as a balll or as long as a kite-string. From fifty yeard away, a fully grown vermicious knid could stretch out its neck and bite your head without even getting up... Can be big as a whale, as long as a truck”
"They travel through space in great swarms, landing on other stars and planets and destroying everything they find. There to be some rather nice creature living on the Moon a long time ago. They were called Poozas. But the vermicious knids ate the lot. They did the same on Venus and Mars and many other planets."

TOMMYKNOCKERS

It remains unclear if Tommyknockers are indeed an alien species or victims of an alien gas that turns individuals of other species into Tommyknocker creatures, drone like beings who instinctively follow some comportemental patterns, such as adapt existing technological material to fit Tommyknockers's needs and create new Tommyknockers. The nature of the gas, an alien tool or a lifeform of its own, remains unknown but its effects have been witnessed in the late twenthieth century in New England.
Upon exposure to an alien atmosphere, the gas is released through oxidation into the surrounding area. Initial exposure to small amounts of the gas results in any sentient creature mutating into a Tommyknocker, a process they refer to as "the becoming." Less advanced creatures are incapable of adapting to the gas and are subsequently killed off by it. The first stage begins with the person gaining the ability to improve (but not understand) the surrounding technology. As the amount of alien gas in the air increases, continued exposure results in the person undergoing drastic change as their teeth and hair fall out and their personalities become increasingly unstable. In the final stages, their skin fades to translucent, their blood congeals and turns green, sexual characteristics fade away, and they become incapable of surviving outside of the gas's influence. Likewise, any person entering the contaminated area during the final stages of the becoming will suffer physical damage similar to radiation poisoning and quickly die.
Tommykockers appear as humanoid creatures taller than a human due to abnormally long legs, feet that ended in a single over-sized claw each, and extended dog-like faces with gray translucent skin and milky colored eyes. Their species lacks any distinctive gender and also possesses telepathic abilities which they use to communicate with each other as well as read the minds of any who aren't like them. Yet despite their hive consciousness and their level of scientific skill, the Tommyknockers are little more than "cavemen from space," who are able to improve technology but not to create it or even harness it to its greatest capabilities. They also have the mentality of unruly children, cooperating only in the most dire circumstances and frequently turning on each other at the slightest provocation.
A Tommyknocker sapceship once crashlanded on Earth due to a fight that had broken out among its pilots. Cast in the shape of an immense flying saucer, the alien vessel was piloted by mental control and powered by the life force of lower-ranking Tommyknockers. The ship stayed burried for centuries until it was exposed to Earht's atmosphere and its gas was released, starting the Tommyknocker process.

VORTEX LIFE FORM

Planet of Origin: Vortex, the third planet orbiting the star Cassandra in the head of the constellation Pegasus.

The Vortex are able to adapt quickly to new environments, evolving into new forms and/or hybridating with local creatures in order to create new lifeforms and are capable of bioengineering to some extent, as well. The Vortex life forms come in several different shapes. All appear to be at least partially, if not mostly or completely, aquatic.

• Larva – Vortex larvae are clear, and shaped like a slightly squashed teardrop; at the large end of the "drop" are two tentacles that look like a chain of bubbles.
• Drones are green or blue in color and have heads shaped like ridged, bladed peanuts, along with thin bodies.
• Soldiers appear similar in shape to dolphins, but are black and very skeletal in appearance, in addition to looking more machine than anima, with exaggerated skull-like head, or ridged, bladed head similar to the standard Vortex drones. These were bioengineered on Earth to withstand high water pressures; they will explode if they get too close to the surface.
• Queen – The Vortex Queen is the mother of all Vortex life forms, and the most intelligent among them. She looks like an extremely large, disembodied Vortex Drone head. Her tongue is prehensile and has claspers at the end that can pull unlucky prey into her insides.
• Jellyfish – Bioengineered jellyfish that behave much like Earht’s jellyfish, they are brown with black spots and they possess one single tentacle at the base of their bodies. They are poisonous even for the Vortex themselves.
• Amoebas – Bioengineered Blob-like creatures capable of travelling through water and air alike. Being airborne seems to weaken them. They are very sensitive to sonars.

The Vortex are a technologically advanced species, They come to harvest from the Earth's oceans every 500 of Earth's years, when the planets are in alignment, because they have lost their own ability to make food. The Vortex hives are mechanical, with cannon-like structures that shoot what may be organic "bullets" for defense in addition to very strong currents of water hostile to non-Vortex life. The hives are mostly underwater, though some parts situated above the surface have been seen; whether this was intentional or a result of falling water levels is unknown. The Vortex know how to produce electricity, and they are known to possess a powerful weapon capable of destroying entire cities located on other planets. According to some legends, Atlantis was destroyed by this weapon.

OVOIDS / BIRKEELS

Planet of Origin: Birkeel, the third planet orbiting the star Jantsak in the Wilky Way galaxy.

A highly enlightened and peace-loving species, the Ovoids successfully conquered death itself. Able to place their essences in fresh, new bodies when their old ones had become too aged or infirm, the Ovoids were virtually immortal.
Although their overall popualtion is of 5 millions individuals, they have developed a space faring but non-expansionnist civilisation.
They possess the mental ability of telekinesis.
They are thin 8 ft tall humanoids with an enlarged heads and yellow skin, and therefore look a lot like taller rigellians but no proof has yet been given leading to believe that both species are related.

RIGELLIANS / COLONISERS

Planet of Origin: Rigel 3, in the Milky Way Galaxy
Rigellians are humnaoid species which developed an interstellar technocratic empire. Their leaders are generally elected due to their high intelligence. Their leader is known as the Grand Commissioner.
They are a humanoid species, looking much like humans with larger heads and a yellow skin tone. They possess psionic abilities which allow them to control others mentally or physicallyt. They can also mentally change their physical density at the speed of thought which allows them to resist any physical forces. They thrive to build an empire via colonization.
The Rigellians are skilled in robotics and have created a race of robotic lifeforms called the Recorders. The Recorders are generally used as scouts to explore new territory and report back to the Rigellians.
Their overall population is of 17.7 billions individuals.
They possess Advanced warp-drive starships, manipulation of subatomic particles, teleportation, robotics, ability to move planets via tractor beams and space warps.
Note: Although smaller, they otherwise look much like Ovoids.

CHIGS

Planet of Origin: Basic chemical compounds from which the Chigs evolved came from Earthm but their evolution took place on the single moon orbiting the Chig homeworld, where they evolved. This moon is sacred to the Chigs because it is where life originated via panspermia and where Chigs still go to be born.

Chigs are a humanoid species which developed a space faring civilisation. They have small, black eyes in recessed eye sockets, with gills on the sides of their head and large, jutting chins. They appear to be unable to survive in atmospheres that support human life as both air and water are poison to them and they must wear armored life-support systems that provide them with the methane they need to breathe.
The Chigs actually evolved from bacteria that originated on Earth billions of years ago: an asteroid collision threw these bacteria into space, carried by meteorites, where they eventually landed on the Chig sacred moon. Life on Earth had already advanced to the eukaryote stage of development, the rate of evolution proceeded slightly faster for the bacteria on their new world, allowing life there to evolve to the point that it could produce the sentient Chigs at roughly the same time that modern humans evolved.
As of the 21st century. Chigs have faster-than-light spacefaring technology and advanced weapon systems. They use a combination of plasma-based energy weapons and ballistic missiles for their aerospace fighters and capital ships. Chig ground forces use anti-gravity hover tanks, anti-personnel plasma weapons and flamethrowers. The Chigs also possess large battleships and a destroyer class vesselr. They also developed a stealth fighter with a hull impervious to standard aerial cannon fire.

SILVER GHOSTS

The Silver Ghosts are an highly advanced non-humanoid species. They are most unique in appearance, being large floating spheres of silvery chrome protecting a fragile inner body. They are largely benevolent explorers, concerned more with science and experimentation than conquest. They come from a world devastated by a supernova early in their history; despite being abandoned to the cold of space ("the Heat Sink" as they called it), the Ghosts survived. The Ghosts are often associated with forbidden experiments, as they frequently toy with the laws of nature to advance their own knowledge.
