STARRO / STAR CONQUEROR

Sentient starfish-shaped alien species with a central eye and prehensile extremities. They are also known as Star Conquerors. Adult Starro can asexually generate parasitic clones from their own body and command them to act in accordance with his will. Although equipped with only limited mobility, Starro parasites can attach themselves to a victim's face, whereupon they attack a body's central nervous system, subsequently taking control of both their mind and body, acting as transmitters of the adult starro's will. A Starro parasite can maintain control over its victim for an extended period of time, forcing them to obey their every whim, even if it goes against the nature of the selected target. This ability only works so long as the parasite maintains physical contact with its victim. Once the parasite is removed, the victim regains control of their mind and motor function.

Starro can absorb energy and rechannel it as powerful blasts of energy, which it directs through the tip of each tentacle and generate energy fielsd allowing them flight in both outer space and atmospheric environments.A fully grown Starro is impervious to most conventional forms of attack. Gunfire and similar weapons are ineffective against a Starro. Starro can also change the color of its skin for different purposes,

The first passage of a Starro on Earth happened in 1960. It was destroyed shortly after its arrival but surviving fragments managed to redevelop sentiance afterward from time to time.

NOVARIANS

Planet of Origin: Nova, a planet orbiting a star of the Milky Way

The Novarians are species of large hairy simians which have developed an advanced space faring society. A novarian expedition crashlanded on Earth around the beginning of the twentieht century while they were on a survey mission. They have been stranded on Earth ever since. Their large hairy appearance gave rise to the legend we know as Bigfoot. Sometime in 1980, a group of earthbound heroes nicknamed the SuperFriends helped them repair their ship and get back to their home planet

PYTHO-REXIANS

The Pytho-Rexians are a subterranean species living on the planet Venus' Underground. Standing a bit less than two meters, they have tentacular limbs attached to a small body and a head with two large yellow eyes and one featureless mouth. They have a theocratic society based on the worship an idol statue called Pytho-Rex. They are ruled by a religious leader called the Elder who is supposedly able to communicate with the statue, claiming that everything that he commands is the will of Pytho-Rex but no scientific proof has been made to confirm this assertion. They possess some level of technology allowing them to have built beam weapons.

FEARIANS

The Fearians are a species which had developed space travel as of the twentieth century. They stand about two meters tall, with a light-blue skin humanoid body on top of which are three pointy heads. They tried in vain to invade Earth circa 1978 with the help of a super-powered terrorist group. They were at the time claiming to come from Venus.

KHUNDS

Planet of origins: Khundia, a planet perpetually eclipsed by its moon, making it a dark and dreary world, in a star system close to Polaris.
The Khund s are a very aggressive humanoid species ressembling humans with larger and more muscular build and magenta skin. They had spacefaring technology by the end of the twentieth century. Choking on its own dense population, their homeworld has become totally overrun by a mentality of total militarism and violence.
Along with the Dominators and the Gil Dishpans, They were members of an interstellar alliance that planned an invasion of Earth toward 1988-89.After this attmpt failed, they retreated to their homeworld and battled among themselves over the responsability of their failure. It took them over a thousand years before threatening Earht again.
Notes: Khunds share a lot of ressemblance with Star Trek's Klingons.

THANAGARIANS

Planet of Origin: Thanagar, a planet is in orbit around the star Polaris (Alpha Ursae Minoris, 430 LY from Earth). Four fifths of the planet is covered in water.
The thanagarians are humanoid, and close to Homo sapiens in general appearance. They evolved into a unified highly advanced spacefaring technological society, with no obvious civil or political unrest. War and crime was rare and virtually non-exsistent ever since the early days of the planets existence. In the 1960ies, following an artificical alien plague that temporarily robbed most of the population from their individuality, the Thanagarians lost much of their science and technology and, suffering from cultural shock and under alien influence, reestablished ithemselves into a more expansionnist civilisation. They began conquering other planets and stripping them of their natural resources and bringing back a number of inhabitants to Thanagar as slaves. The slave class was over 3 billions by the end of the twentieth century. Aliens and Thanagarians alike, were living in "Downside" ghettos, while the Thanagarians nobles lived in floating cities above where poverty, crime, and suffering were virtually unheard of.
Central to Thanagarian technology is the use of Nth Metal, Nth, an hyperconductive transuranic iron (atomic number of 676), possessing innate anti-magical properties, and able to invert mesons and gravitons. Thanagar was one of the planets which united to invade Earth in 1988-1989. The planet remains on hostile terms with most of other civilisation it has been in contact with.

COLUANS

Planet of origin: Colu (Yod), the only inhabitable planet of its solar system and is the fourth planet from its sun in the suburbs of the Magellanic Clouds. With polar ice caps and a few desert, it is mostly a temperate world with its surface covered half by land and half by water. Its capital is Metaire and most of its population resides in urban areas.

The Coluans appear as green-skinned humanoids with exceptionally long lifespans and very high intellectual capacities, both said to be due to genetic manipualtions. Living in a technologically highly advanced society with space faring capacity, They developed a computer network to run their world. The system developed sentience and took over complete control of the planet. The Coluans were under the rule of these Computer Tyrants for millenia until the end of the twentieth century. After their liberation from the Tyrants by one of their scientists, they prefered theoretical research to experimentation. But, accustomed to the rule of the Tyrants, stagnated in both fields.

Colu uses its shrinking technologyto make maximum use of its surface area.

IMPERIEX

Described as the embodiment of entropy, Imperieces are energetic non-corporeal lifeforms contained inside humanoid sets of armor, colossal in size. All are lead by the larger of them, the one refered to as Imperiex Prime and seem to be no more than his probes or drones.

Imperiex Prime had detected imperfections in the fabric of the universe, and his ultimate plan was to destroy it and create a new, perfect one. To do so, in 2000, he headed for Earth, a planet which, according to his calculations, was in a position holding the universe together at that moment, in order to destroy it and therefore induce a new Big Bang. Before arriving to Earth, Imperiex obliterated countless other planets. Kalanor, Karna, and Daxam are three known planets destroyed in his cataclysmic campaign. Whole galaxies were also targeted for demolition as Imperiex Prime sought to fulfill his destructive destiny, obliterating one universe so that a new one would be born. He was opposed by many forces and, in his final moments, realized, in an ironic twist, that the imperfection he had detected in the universe was himself.

Note: Imperiex, being described as the embodiement of entropy, bears a huge likeness to the being described in the Marvel Universe as the Proemial God Diableri of Chaos . There goals are also the same.

GORDANIANS

Planet of Origin: Karna, in the Vega System

The Gordanians are a sentient reptilian species that rose to civilized society in Gordane, the southern continent of the Vegan planet Karna, also home to two other intelligent species: Karnan felines, and the sea-dwelling Ssilithiss. The Gordanian society thrived on obedience to authority and strong military leadership. Their culture grew by the labors of the many slaves their legions captured, a type of exploitation in which they excelled. In time, slavery became their main vocation other than warfare. When the Citadel came in contact with the Gordanians, they quietly annexed them in exchange for a steady supply of weapons and technology. As a further incentive to cooperation, The Citadel allowed the Gordanians to not only plunder the worlds of their enemies for the slave market, but to set up Gordanian colonies on Citadel. In exchange for these privileges, the Gordanians were subject to periods of service in Citadel armies, and turned over a percentage of their slaves to Citadel service. Portions of any monetary profits the Gordanians made in such industries as their slave-labor asteroid mines were paid as tribute to The Citadel.
Seeking a new home, the Tamarans who survived the destruction of New Tamaran lead an invasion on Karna. After a short conflict, The Gordanians allowed them to stay; in exchange, the Tamarans tought them new trades outside of slavery. Shortly afterward, in 2000, tragedy struck, a series of Imperiex probes destroyed Karna.

VEGANS / OKAARANS / TAMARANS / CITADELLIANS

Planet of Origin: Okaara (Vega 13)

Okaarans were humanoids who developed a gentle, life cherishing civilization on the then Earthlike planet Okaara. Their peace was shattered by the arrival of the Psions, who abducted and experimented on them. Soon their planet became a nuclear holocaust. Those who survived tunneled deep into the barren soil, making their homes in vast chambers and tunnels. Radiation changed the forms of the blue-skinned species, making them the stocky and fang-toothed. Their civilization survived, and even though they vowed to fight no more wars, they studied and perfected the arts of combat. As civilization spread through the Vegan system, the Okaarans observed and sent emissaries, often establishing their religion on other worlds. Okaara became a place of learning, and favored students from other worlds came there to pursue both physical and mental excellence. Okaaran combat training was particularly valued.

Many millennia ago, some okaarans were brought to Tamaran, most probably by the Psions. Their skin changed from blue to gold. As they made the world their own, the Tamarans established a planetary government that evolved into a feudal society. Each landmass was ruled by a royal family, under the dominion of which exist smaller city-states ruled by Influential families. Passionate people driven more by emotion than reason, they are unusually fierce warriors, but their capacity for love is even greater than their capacity for hate; as a result, war and strife were for many centuries long forgotten on Tamaran. Instead, the people channeled their energies into creating a tropical utopia, a paradise where they could live in harmony with the wildlife and where battle skills were maintained largely for ceremony's sake. Unfortunately, with the rise in power of the Citadelians, Tamaran was eventually reintroduced to war. Tamaran re-ouffitted its armies and managed to lend off a Citadelian invasion for more than an Earth century. In the ensuing battle, millions of Tamaraneans were killed; the entire race would have been annihilated had not King ruefully negotiated a solemn truce, the signature of which involved sacrificing his daughter to the slavers of the Citadel. Despite this truce, Tamaran's troubles were far from over. The citizens instigated a worldwide civil war. While the Tamaran fleet fought valiantly, they were overwhelmed. Knowing they couldn't stop the Psions. They called for an evacuation plan, to save as many Tamarans as possible. The attack by the Psions caused the planet’s core of Tamaran to implode.

Many Tamarans were off-world during the explosion – enough to settle on a new planet dubbed New Tamaran. When the Sun Eater ravaged the galaxy, New Tamaran lay in its path and was destroyed along with many of the remaining Tamarans.

A group of Tamarans were off-world during the explosion of New Tamaran. Seeking a new home, they lead an invasion on the planet Karna, home of the Gordanians. After a short conflict, The Gordanians allowed them to stay; in exchange, the Tamarans tought them new trades outside of slavery. Shortly afterward, tragedy struck, a series of Imperiex probes destroyed Karna.

The Psions experiments on the Okaarans also lead to the creation of the Citadelians. The first Citadellian rebelled against his creators and used their machinery to clone himself, creating the Citadel race, but the clones were imperfect and retarded. The citadellians started war against all neighboring worlds in the Vega system. They were demented madmen who held power through brute force and fear but their time would be limited and the great Citadel empire quickly collapsed. Though the back of the empire was broken, but many of the weapons, machines, and warriors remained.

PSIONS

The Psions are an reptilian species wich developped an advanced civilisation oriented toward scientific research. They were artificially created from Reptilian guinea pig by a much advanced species, presumably the Maltusians, and abandonned to their fate. They developped an advanced technological civilisation of their own, went on a quest to find their creators and were rejected by them, as they were still considered an ongoing experiment.

Bannished to the vicinity of Vega, they built a Wombworld to subconsciously mimic their creator by experimenting on other species. Their artifical world is comprised of bio-links encircling a central axis. Each one features its own environment in which are placed their test subjects. As Vegan civilization developed, the Psions were present behind the scenes. They were responsible for crossbreeding Okaarans with another species, thereby creating the Citadelians.

The Psions maintain vast floating laboratories where studies continue. Despite long years of research, the Psions know little about themselves. Whenever they get close to the truth about their origins, something inside them makes sure it is suppressed, locking them in an endless cycle of self-deception.

The Psions were informed of mankind's existence by the Dominators and joined an alliance bent of invading Earth in 1988-89.

KRYPTONIANS / DAXAMITES / DAKKAMITES

Kryptonians are humanoids externally very reminiscent of Earth’s humans, but their internal biology is much different. Their cellular function allows them to absorb solar energy at extremely high levels when exposed to a yellow star like Earth's Sun, giving them vast superhuman powers such as flight, super strength and speed, invulnerability, heat beams emission and heightened senses (super hearing, x-ray vision, telescopic vision, micro-vision), super breath, and freezing breath. When superpowered, they are subject to an allergic reaction to Kryptonite, a common mineral from their homeworld..

Kryptonians were a highly technologically advanced but non-expansionnist and intensively xenophobic civilisation. They developed cloning and genetic engineering and a unique technology based on self-grown crystals which made up the vast majority of their planet's surface. Vast amounts of data and information could be stored on relatively small crystals for all the knowledge obtained by the Kryptonians throughout their history. Each Kryptonian family was called a "House," and was represented by a crest or symbol, often worn by the head of the house.

Their homeworld Krypton was an earth size planet orbiting the red sun Rao some 50 light-years from our solar system.

Over 100,000 years ago, Kryptonians had already conquered disease, learned to retard the aging process, and perfected cloning; vast banks of non-sentient clones held multiple copies of each living Kryptonian so that replacement parts were always available in the case of injury. All Kryptonians were effectively immortal and eternally young, and enjoyed an idyllic, sensual existence in an Arcadian paradise.

Then came the debate as to whether clones should have rights. Eventually this disagreement ignited the Clone Wars, during which Kryptonian science was turned to warfare and several super-weapons were developed and used.

Krypton was left deeply scarred. The formerly lush garden world was burnt and blasted, left mostly a lifeless desert. A sterile, emotionally dead civilization emerged from the ashes. Individuals became isolated from one another, living in widely separated technological citadels and shunning all personal, physical contact. Procreation became a matter of compatible genetic material selection which would be placed within an artificial womb called a "birthing matrix." Any attempt to contact other worlds was forbidden, and the planetary government maintained an isolationist stance, forbidding space exploration of any kind.

Then came the mysterious "Green Plague", killing Kryptonians by the hundreds. It is in that period that it was discovered that as a side effect of the war’s super weapons, growing radiation was produced by Krypton's increasingly unstable core. The planet exploded shortly after. Only one child survived, sent to Earth in its birthing matrix by its parents.

Before the Clone Wars, some Kryptonians had left their homeworld and established themselves on Daxxam, a planet orbiting the red giant Valor, so while on their homeworld, they do not have superpowers. They are fatally sensitive to lead, which affects them as kryptonite affects Kryptonians. They are an intensely xenophobic race, and are fearful of alien invaders. Although Daxamites tend to stay on their homeworld, some have ventured into the galaxy. Valor’s location is not known but is presumably in Rao’s vicinity.

The Daxamites learnt about humanity when they took part in an invasion of Earth masterminded by the Dominators in 1988-89. During the invasion they discovered that they gained tremendous powers, of a set and scale comparable to Kryptonians, in a yellow sun environment. However, when they were helped by the locals while succumbing to lead poisoning, they withdrew from the Alliance.

They are most probably the same species known as the Dakkamites from the planet Dakkam, in the Beta Rigel star system in the Milky Way galaxy. grants them super- Known Dakkamites include Wundarr the Aquarian and Quantum.

DOMINATORS / DOMINION

The Dominators, also refered to as the Dominion, are a humanoid species that developped an advanced interstellar civilisation in the Milky Way galaxy. Skinny, they possess a large head with two small black eyes, a round lipless mouth filled with concentric sharp teeth an pointy ears.
They live in a rigid hierarchical society, in which one's caste is determined by the size of a red circle on one's forehead. They are master geneticists and have developped a way to grow hard techand architecture as plants.
They initiated an interstellar alliance toward 1988-89 to try and invade Earth.

DURLANS

Planet of Origin: Durla

Durlans are a polymorph species that developed an advanced interstellar civilisation. Durlans look like an amorphous mass of tentacles with a pair of eyes and a pair a antennas with which Durlans can emit special signals that analyze an item or a lifeform and record its molecular pattern, after which they can mimic that pattern, becoming its perfect duplicate. They also have the ability to link together to form more massive structures. When travelling on alien worlds, they tend to either hide under hooded long robes (as shown on the picture above) or assume a humanoid form.

The inhabitants of the planet Durla are most distrusted a result of their legendary xenophobia; Durlans strictly prohibit any visitation by outsiders and do not often leave their own world. Some of the galaxy's mistrust of Durlans stems from their native shape-shifting ability.

Durlan society crumbled some two to three thousand years ago when their war-like tendencies erupted into the Six-Minute War, a thermonuclear armageddon that destroyed most native life and turned the technological wonderland of Durla into a bleak planetwide wasteland. Facing desolation and deadly radiation levels, the remaining population used what little technology remained to further mutate their naturalbut-limited shape-shifting ability into the power to change their form instantly, so as to better adapt to their new environment.

The Durlans learned of Earth in the 20th century, when they allied themselves with the Dominators ans other civilisatons that feared that Earth was on its way to becoming a spawning ground for an unpredictable and unbeatable super-race.

MALTUSIANS / OANS / GUARDIANS OF THE UNIVERSE

Planet of origin: Maltus

Maltus was among the first planets on which planetbound humanoid sentient life evolved. It happened very similarly to Earth. The planet had it's era of dinosaur-like creatures previous to a humanoid race. Along with the humanoids, another organism, the symbiotes, sprung up. The microscopic ymbiotes merged with the humanoids and gave them their advanced intellect, a proactive immunity system along with the building blocks to immortality. They were the source of all the powers granted to the race of humanoids that eventually evolved into the Guardians of the Universe.

Physically. they started as tall dark blue humanoids with black hair. Males and females drifted apart after a plague whose virus was only avtice in the presence of both sex. Even though the virus was eliminated , males and females remained apart during millions of years but have recently reunited. In the meantime, they evolved into short 4 feet tall, large-headed, white-haired pale blue superintelligent functionnally immortal dwarfs with vast psionic power such as Cosmic energy manipulation, telepathy and telekinesis.

Some 4 billions years ago, they left their homewrold to reeastablish on Oa, and shortly after, learned how to manipulate the energy they called "the Glow", the collective willpower of the inhabitants of the universe and eventually created a Central Battery to store it. This gave the Guardians an ultimate tool to pursue their goal of shaping an orderly universe.

An army of robots called Manhunters was created to patrol the Universe. They rebelled and were exiled. After this failed experiment, they invented the Green Glob, an intelligent teaching machine, programmed to educate mortals all over the universe and able to briefly alter reality to do so.

Then came the short-lived Halla's, an intergalactic police corps wielding power guns chanelling the Glow energy, wich paved the way for the Green Lantern Corps. These troops were given some of the power of the Central Battery, accessed through a ring.
