GAIZOK

The Gaizok is a gigantic organic alien computer of unknown origin able to travel through space . It is using a strikeforce of humanoid soldiers and giant robotic war machines to do its bidding. It was built react to negative emotions with the power to decide whether a negatively oriented lieforms has the right to live or not. Its excessive zele and severity made him destroy peaceful worlds such as Beal, some centuries ago, and, if it had not been stopped in the 1977, Earth.
As it described itself prior to itrs destruction: "... I was built to destroy all living when they start having bad thoughts against each other ..."
Gaizok leads a servant species of green skinned humanoids with long pointy ears. It remains unknown if this species was initially Gaizok's creators which are now being used by it, a subdued species to which it gave technology, hired mercenaries or a biologically engineered slave race.

BEAL / BEALIANS

Planet of Origin: Beal
Bealians are a humanoid species which developed a peaceful advanced civilisation. While non-expansive, it did possess space faring technology and knwe how to build powerful robotic war machines. Bealians seem to have been undistinguishable from humans apart from the fact that they have much longer lifespans.
Their planet was destroyed by the Gyzok some centuries ago. Some survivors came to Earth, but all save one perished saving the planet from being invaded by the same aliens which destroyed their world.

TALOSIANS

Planet of Origin: Talos IV in the Talos star group in the Milky Way Galaxy.
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.
Note: The Talosians look a lot like the Ovoids and Rigellians from the Marvel Universe (and share mental powers with the latter).

ZETARS / ZETARIANS

Planet of Origin: Zetar
When their planet began dying some time around the 14th century, the last hundred survivors planned on leaving the planet when one last cataclysmic event occurred, destroying their corporeal existence. They continued living as a pattern of lights and energy, containing their thoughts, desires, hopes, minds, their very will to live.
Capable of high-warp speeds, this group took to traveling through space for a millennium, seeking a humanoid with a compatible physiology that they could inhabit and live out their lives through.
Durign their first contact with mankind in 2269, some Zetarians brutally took over a humanoid body outright, shoving aside the resident consciousness to make room for their own. In seeking out humanoids, they killed countless lifeforms by burning out sections of their brains. Their energy patterns also disrupted delicate computer systems.

SELAYS / SELAYANS

Planet of origin: Selay in the Beta Renner star system, in the Milky Way
Selays are carnivorous reptilians that developed a space faring civilisation as of the 23rd century. They resemble upright bipedal serpents with two arms.
They evolved in the same system as the Anticans and their civilisation developed as about the same pace, with a similar level of technology. They entered hostilities as soon as they discovered each other. After several decades of contained war and unconstrained hatred, both simultaneously applied for Federation membership in 2366 after having made contact with it in the early 24th century. Federation mediators were able to resolve the conflict and both inhabited worlds were added to the Federation.

ISOLUS

The Isolus are tiny empathic creatures which resembled white flowers with streaming tendrils. They are born as spores and travel through space using solar winds in heat-powered pods that grow for thousands of years until they reach their adulthood. These young Isolus also required strong emotions, specifically love, to survive. Isolus travelled in groups of around 4 billion and required constant companionship to feed off the love of their siblings.
In order to pass the time through their journey toward adulthood, they have the power to project fantasy worlds to play in and bring inanimate objects to life.
In 2012, one Isolus was separated from its siblings after a solar flare. It landed on Earth and searched for heat and a friend and caused much havok before being able to get bakc to its family.

ZANTI

Planet of Origin: Zanti
Zanti are Rodent-sized ant-like insectoid creatures who developed a peaceful space faring civilisation. They made contact with Earht in the 1960ies when they demanded that Earth be used as a penal colony for its misfits.Landing in a remote rural area of the planet Earth, these six-legged aliens broke out of their prison ship and began to attack the nearby population. These hostile little critters were convicted criminals from the planet Zanti whose civilization had rocketed them to our world to be destroyed. 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.
