BONELESS

The Boneless are beings from a  two-dimensional universe. They shortlt managed to invade our tridimensional worlds in 2014 in Bristol, UK. They are able to reduce both lifeforms and other three-dimensional objects to two-dimensions and back to a rough tridimension afterward, with the ability to possess them.

DAVANNANS

Planet of Origin: Davanna, in the Milky Way galaxy
The Davannans are a humanoid species wich developed an advanced emotionless civilisation with space faring capacities which, as of the 1950ies, was dying from the aftermath of a devastating nuclear war of their homeworld combined with an epidemix which caused their blood to evaporate.
The look very similar to humand but with white pupil-less eyes. They are telepathic and, focussing their eyes on a subject, capable of hypnosis and even killing by destroying the optic and nervous tissues of the victim.They feed on a black liquid containing all the nutrients they need. They are very sensible to loud sounds, which can be very painful to them.
In 1957, they sent a scoutto study the effects of Human blood in their own biology, but after they lost contact with him, they decided not to go on any further with potential invasion plans. A fact they never knew, their scout had in fact died in a car accident.
The alien had brought with him a non-sentient creature from his home planet, which resssembles a mix between an octopus and a flying umbrella and which could attack people by jumping at their head and covering it with its surface.

DAGGRA

The Daggra are a vaguely humanoid species which had developed a space faring civilisation as of 2002. They are vaguely reminiscent of the classic E.T. the extraterrestrial, but larger. They possess telepathic powers,  a large flat head with a pair of large eyes, a long neck, long and thin arms with 3 digits. On other worlds, they protect their fragile body inside power armours.

In 2002, a daggra spacecraft crashed  into Mount Ibuski, Japan and was captured and contained in the National Institute of Space Science, but not before it had managed to send a creature relayed a distress call to its Mothership. Whether accidentally or intentionally, the creature was killed an gesture that sparked a war between the Daggra and humanity in which humanity was nrealy wiped. Survivors hiding in Tibet managed to build a machine called the Time Shifter, which they used to return to the past and prevent the war from starting by rescuing the alien and returning it to the Daggra, therefore erasing the whole war timeline.

MOON / MOON CREATURE

The moon creature is a giant living creature which had been developping inside its egg, Earth's moon, for possibly as long as 4 billions of years. It hatched in 2049 after an intense one year growth period during which it increased its mass dramatically, breaking the Moon's crust in the process.

At birth, it weighted 1,3 billions tons, most of it being the egg it itself was ready to lay as soon as it was being born, and which was to become Earth's new moon, along with the dust left by the disintegration of the former moon's crust.

The creature itself is composed of a short somewhat moth-like body with long flayed tail and of two pairs of diaphan wings that composed most of its mass. After laying its egg, it flew away toward deep space.

Its whereabouts afterward remain unknown, as do its origins: was the egg initially layed by another creature or did it evolve on spot, possibly as a result of the planetoid Theia with the Earth. This also raises the question of a possible panspermia originating from Theia. But this hypothesis is highly speculative.

Here are two 3D echography of the Moon dating hours prior to its hatching.

BYNARS

Planet of Origin: Bynaus, a planet oribiting the star Beta Magellan, in the Milkty Way galaxy within a 1000 light years of Earth.

The Bynars are a species os short genderless sentient humanoids with lilac skin and enlarged skulls. They have a patch of dark purple hair on both sides of their neck and asymmetrical ears. They work and live in pairs, usually with a matching asymetries to equate to a symetry. Their primary language consists of high-frequency sounds, unintelligible to humans but they are able to change frequencies down to communicate with other species.

They developed a technologically advanced civilisation in such a way that at birth, each bynar's parietal lobe is surgically removed and replaced by a synaptic processor taht allows them to connect directly to a central master computer they built on their homeworld. Every Bynar is equipped with a buffer, carried at their waist, to help them manage the  rate of information they send and receive.

In 2364, due to a nearby star going nova, they were temporarily forced to shut down their computer which caused a planetwide black out.

TELLERS

The Teller are large muscular sentient humanoids gifted with powerful telepathic powers. They have grey elephant-like skin and elephant-like feet, a vaguely snail-like head with articulated eye stalks on each side of it, a short ribbed tail and two long claws serving as hands. Their nostrils are presumably situated under in series, along their eye stalks. One of their main defense mechanism consist of emissions of psywaves that can liquify the brain of their victims, indicently causing the skull to cave in.

They probably developed a primitive culture on thier howeworld but were all exterminated after being discovered by offworlders, presumably humans, at some point in the future. Two were kept alive to serve as guilt detectors for a galactic bank until the bank was closed and they were relocated to an uninhabited world.

ZYKARIANS

Planet of Origin: Zykaria

Zykarians are two species living in symbiosis, one being looks much like a humanoid headless body, the other, much like a human head. The body by itslef seems to have limited initiative, most of the thinking for both being done by the head being, which in exchange, rely the body for locomotion, prehension, protection and sustainance. It is important to note that the head needs the help of the body to disengage itself from the ladder.

Zykarians have been known to ingest food by the mouth, which leads to believe that the head is a channel to get nutriments in the body who is in charge of digestion. If it is the only channel remains unknown.

No Zykarian females has been seen by members of other species and their existence in fact remains a big point of interrogation although, while the Zykarian reproductive cycle is unknown, it has been reported that some individulas have displayed some levels of attraction to females of other species such as humans.

Zykarians have developed an advanced technological space faring if somewhat secretive civilisation as of the 25th century with occasionnal contacts with Earth.

PROCESS

The Process is oviparous wormlike sentient annelid parasite looking much like a leech with lamprey-like mouths at each end. It moves by cartwheeling itself end over end, leaving a slime trail behind. It had clawed fins and red-brown skin which turned grey with age. It possesses some psychic powers and traps its victims in silk cocoon to  feed on their mental energy but also appears to be datavore, sustaining itself by consuming information.While originally not bigger than normal leeches, with enough food, it is able grow the several meters in lenght.
Its origin is unknown but one specimen is known to have been in Ealing, UK, during the 1990s, at which point it got on stow away in a time machine and disappeared from the planet.

POD PEOPLE / BODY SNATCHERS

The Pod People are a nomadic alien species of small gelatinous creatures originating from a dying planet. They evolved the ability to defy gravity and left their planet in search of a new world to settle on to float in space for millenia before occasionnally landing on suitable worlds. The Pods' sole purpose in life was that of individual survival, with no attention given to the civilizations they conquered or the resources they squandered. They would then consume all of the planet's resources, only to then leave in search of yet another new world. It is hinted that such a consumption was the fate of the civilizations that once inhabited Mars and the Moon. 

Upon landing on a planet, they would try to replace the dominant species by  growing into large plant form which would spawn emotionless replicas from its pods; As a pod reaches full development, it assimilates the physical characteristics, memories, and personalities of any sleeping person placed near it; these duplicates are devoid of all human emotion. The assmiliation process would leave the original bodies to disintegrate into dust once the duplication process was completed. The duplicates had lifespans of only five years, and could not sexually reproduce.

Earth was among the planets the landed on. Stories of case where such cases happened

In 1956, they landed in a small California town. Alien plant spores grow into large seed pods, each one capable of reproducing internally a duplicate replacement copy of each human. A local doctor uncovers what is occurring and managed to stop the invasion with the help of the Federal Authorities.

In the 1978 invasion, the pod landed in San Francisco and managed to bring their effort further. The replicas showed the ability to communicate thru scream in a creepy alien voice to alert other pod people of those not yet taken and seemed to exhibit a kind of extra-sensory perception. Replicas merging more than one subject were also witnessed like a case of a merged man and his dog.

As similar scenario happened in 1993 in an Alabama Amry base.

In 2007, the invaders changed their method, from pods, they made contact with humans directly through liquids and then worked much like viruses which,  once the person had fallen asleep,  rewrote human DNA. The aliens then vomited a gelatinous substance into liquids to help the invasion continue. When the invasion gains considerable strength, the pod people transform humans by directly injecting them with the substance, under the guise of "influenza vaccines".  However, it was discovered that people who had certain illnesses during childhood were completely immune to the virus. A vaccine was created and the entire pandemic is cured within a year; those infected, after being treated,we re unable to remember events during their infection, "as though they were in a deep sleep".  In one California town, though, the invaders used their traditional method, but with more egg-like pods.

SONTARANS

Planet of origin: Tthe moon of planet Sontar (AKA Sontara), a planet with 5 times Earth's gravity, in the Milky Way Galaxy.

Several thousand years ago, at a time when the Kaveetch people, a humanoid species native to Sontar which had developed an advanced space faring civilisation, were losing a war against the Rutan Host and coming close to extinction, they established on the moon of their homeworld an infrastructure allowing them to mass produce clones genetically engineered to excel in the art of war. The belligerent and militaristic Sontaran clones managed to fight off the Rutan assaults and got rid of the remaining Kaveetch they deemed inferior to themselves. The existence of their creators was eventually erased from their history. Their revised origin presentedand rewritten as them as a species split into clans, which fought amongst themselves until the arrival of a common foe, the Rutans, forced them into unity.

The Sontarans are grey-brown skinned greenblooded  humanoids. They have have large potato-like neckless heads, three fingered hands and short stocky bodies. Due to the high gravity of the moon of Sontar where they were first created, they have great strength and resilience in lower gravity environments. Although extremely resistant, they are vulnerable to coronic acid. They absorb energy via the probic vent on the back of their necks. A sudden blow to the vent would stun them while the penetration of a sharp object into it will kill them. Tampering with the energy feed could also lead to a reversal effect that could destroy them from the inside out.

The Sontarans are capable of creating around a million clones every four minutes, grown in vats and were nourished by sezerfine gas, and are therefore able to sustain massive casualties.  They can also heal their wounds with a stubby tubular device called a tissue rectifier.

The Sontaran technology has allowed them to miniaturised FTL technology to a point where small one men craft have interstellar range. Whatever their size, their starships are usually spherical. They use teleportation technology using generators situated at area of materialisation and dematerialisation, and limited time travel technology which they inherited from the Kaveetch. By the 13th centuray, they used osmic projection. In the 20th century, they started making attempts to obtain more effective time travel

Sontarans also used mind control individuals, either taking over their minds through rheon carbine, a thin, metallic weapon, which was designed to optimally fit the Sontaran hand, and was used for energy projection and hyponotism; or controlling them with devices attached to the neck.

Sontarans used a Base-6 counting system.

They are known to have visited Earth during the ancient Egyptian civilisation, where he was worshipped as a god until the humans learned that he planned to destroy Earth, at whihc point he was buried alive in a pyramid.  

In the 13th century, a scout, landed in England and claimed it for the Sontaran Empire. He proceeded to make an alliance a local warlord, and to transport scientists from the late 20th century into the past using his osmic projection. He would then hypnotise them in order to make them work on his ship.

From that point on, several sontaran scoutships eithet landed or crashed on Earth, most of the time with fatal results, like the one that crashed in  Tunguska in the 1920ies. But it is not until 2009 that an all out invasion of the planet was attempted. As the Sontarans were momentarily losing their eternal war against the Rutans,  the Tenth Sontaran Battle Fleet made plans to convert Earth into a cloning world but failed, resulting in the destruction of their fleet.

BA'NETH

Planet of origin: Unknown, in the opposite quadrant to Earht in the Milky Way galaxy.

The Ba'neth are a non-humanoid sentient species which has developed an extremely xenophobic and reclusive space faring civilisation as of the 22rd century. They possess 3 sets of tentacles on the side of their boyd, whihc can be used for either locomotion or prehension, along with another one at the back of their "neck", which is normally used over their head, and another one at the base of their body, whihc serves as a tail and to help stabilise them in a standing position.

BA'KU

Planet of origin: Unknown, relocated to Ba'Ku, a ringed planet in The Briar Patch, AKA Klach D'Kel Brakt, in the Milky Way, a region containing dangerous space matter including the remains of supernovae, false vacuum fluctuations, metaphasic radiation and at least two habitable planets, one of which was Ba'Ku. 

The Ba'ku are a humanoid species almost indistinguishable from humans, which, in the early 21st century, developed a civilization capable on space travel as well as the means of building weapons of mass destruction which brought them to the brink of self-annihilation. A small, enlightened group of the Ba'ku people escaped the horror of their homeworld and found an isolated planet where they followed a simple way of life and prohibited themselves from using technology. The metaphasic radiation in the planet's rings caused their aging process to significantly decelerate, making them nearly immortal. 

A younger generation, eager to explore the galaxy, rebelled against their elders. Unsuccessful, they were exiled in the late-23rd century and eventually became the Son'a people, a nomadic interstellar power, living under the direction of the Son'a Command. Narcissistic and materialistic, they put great values in metals and ores and raided inhabited worlds for these resources, often using slave labor. Without the regenerative effects of the Ba'ku homeworld's metaphasic radiation, they became infertile and worked heard ot retard their death by any possible means, including genetic manipulation and surgical techniques. Some sociologists attributed their aggressive behavior to desperation. 

In 2375, First Contact between the Ba'ku and the Federation was established during a failed cultural observation mission, when a monitoring post was discovered on the planet. This came at a moment of tensions between the Ba'ku, the So'na, the two groups were reunited.

ELDAR / SPACE ELVES

Planet of origin: Unknown, in the Milky Way galaxy

The Eldar are an ancient race of tall and slender extremely very long-lived human-looking humanoids, with much faster metabolic rates than humans, as well as better reflexes and a superior intellect. They were created by the Old Ones some 65 millions years ago to serve in their War against the C'Tan and their Necrons servants. Following the departure or disparation of their makers at the end of the war, they became a dominant species in the Milky Way galaxy. They possess strong psychic powers and have a fair amount of their population endowed with some level of prescience.

It is so believed that within the upcoming 28 000 years, they will come close to extinction, with survivors existing in a few wondering craftwords, planetoid sized spaceships, hiding among the stars. The reason of their fall will come from within, as consumed by arrogance and with no need for substantial work , the pursuit of their desires will lead them toward a path of instant fulfillment and unbridled violence. The psychic emanations of these activities will give the Eldar vices a life of its own, a consciousness known as Slaanesh, the Devourer of Souls, whose psychic scream of birth will tore the souls from all the Eldar within a thousand light years of it and plunge the Eldar homeworlds into a limbo of partial existence, a region which will become known as the Eye of Terror, a bridge between real space and the Warp, the psychic imprint of all the souls within the Milky Way. 

Much of Elda culture is based around their mythological cycles. The most famous of these cycles was the War in Heaven, an epic conflict between the Eldar deities, in two factions lead by Vaul, the god of the forge, and Kaela Mensha Khaine, the god of war, which is based on the war the Old ones led against the C'Tan and their Necrons servants some 65 millions years ago.

Eldar technology is notable for its use of Spirit stones, wraithbone and the Webway.

The Eldar use spirit stones to capture, contain and protect their souls at the moment of death. These stones are then collected and inserted into their Craftworld's "Infinity Circuit", where they may rest along with the spirits of their ancestors. In times of need, the spirit stones of the Craftworld's strongest warriors may be taken from the Infinity Circuit and placed inside Wraithbone automatons to once again fight for the Craftworld. 

Wraithbone is the main construction material of the Eldar, and the staple of their psycho-technic engineering. It is pyschic energy solidifed into mattter through psychic power. It is a psychic conductor and so not only provides the structure for the things built of it, but also power distribution and communications. Wraithbone is a highly resilient material, and capable of limited self-repair. It, and the other building materials of the Eldar, will grow and react more like tissue and plants than the building materials of other races.  Every Eldar Craftworld contains an Infinity Circuit, which is the Wraithbone skeleton of the Craftworld . Within this matrix the souls of all the Craftworld's dead reside in a form of group consciousness, providing both a well of psychic power for the ship and a massive ancestral mind to advise and guide the living. The Infinity Circuit is the closest thing that the Eldar have to an afterlife; if their souls are not caught and integrated into it, they will be lost into the Warp and subject to its perils. For this reason the Eldar will defend their Craftworlds with a fury and tenacity almost unrivaled; they risk losing not only their home but their souls and that of their ancestors.

The Eldar travel through the galaxy by use of the Webway,  a system of ancient "tunnels" through  the Warp but completely isolated from its inherent dangers. It is a vast and tangled network of doorways between fixed points in real space, by which the Eldar can travel far more rapidly than most races.

FLYING SAUCERS ALIENS

The Flying Saucers Aliens are a humanoid species looking much like a frailer version of humans which developped an advanced technnological civilisation and achieved interestellar space travel technology. They had to flee their home planet and entire star system was destroyed when their sun went cold centuries ago. Claiming to be that those inside the saucer fleet orbiting the Earth  are the last of their species, they tried to invade Earth in the late fifties after some a dozen of artificial satellites had been put into orbit by Project Skyhook. After launching an attack on Washington, Paris, London and Moscow, they were destroyed by a weapon that could negate their saucers' magnetic propulsion system.

VENUSIANS / YMIR

 

Primitive but not-aggressive unless provoked, the Ymirs are oviparous green skinned two meters tall  reptilian scaly bipeds with a long forked tail and a sagittal crest that extend into a long ridge running from the top heir head to their tail. They have a humanoid torso. Both their arms ans feet are clawed and three-fingered. Their lower legs are turned backward and their face has vaguely simian features, with jowls hanging from their cheaks. They have large nostrils, pointed ears and a pair of eyes surrounded by protective ridges. They have no heart or lungs but a "network of small tubes throughout (their) entire body" and breathes through 'fiberous filtering elements" that protects it from airborne poisons. They breathe sulfur. Under otherworldly conditions, Ymirs are known to be able to grow to much exotic proportions than their native one. On Earth, for instance, they have been known to grow up to 7 meters.
