IXODES / CRAWLING EYE / TROLLENBERG TERROR

The Ixodes are a sentient non-humanoid which developed a space faring civilisation who look like a several meters wide fleshy balls cover with bulging veins with a giant eye located frontally on their equator and several powerful tentacles about twice as long as their body which they use both for prehension and locomotion. They generally move about surrounded by a cloud that provides them the subzero temperatures they need to survive.

They are known to have settled camps on some of Earth's mountain tops in the 1950ies for reasons unknown but following aggresive behaviours, were either destroyed or chased away. The means they use to travel through space remains unknown.

B'SAARI

Planet of Origin: B'Saari II, the 2nd planet of a solar system of the same name, circa a 100 light-years from Earth, near the star Denobula.

The B'Saari were an intelligent spacefaring species which were the first species whith whom the Denobulans made contact, some times prior to the 19th century. They had a technique for reviving the deads reminiscent of the one exhibited in the film Frankenstein, which left the rivived with functionning with basic neural and metabolic functions.

BO'MAR

 

The B'omar are a sentient xenophobic humanoid species which developed an isolationist faster than light space faring civilisation that established itself on several worlds of the Delta Quadrant, the quadrant of the Milky Way opposite to the one Earth it in. Their government was known as the B'omar Sovereignty. Externally, they ressemble humans with the exception of a cranial ridge that prolonge itself to the end of their nose, which much flatter and wider than that other humans, with nostrils far apart.

The B'omar were neighbors with the Nassordin, with whom they had delicate trade negotiations.

KILAAKS KILAAKIANS / キラアク星人? / KIRAAKU SEIJIN / KILAAK PLANET PEOPLE

Planet of Origin: Kilaak (position unknown - the Kilaaks claim it is between MArs and Jupiter, but show no evidence on the matter)

The Kilaakians are a species of small metallic worm-like creatures with a space faring and mind control technologies who live in high temperature environments.

They  travelled to Earth circa 1999, establishing a base on the moon and posing as  a race of female humanoids from the planet Kilaak, which they said was between Mars and Jupiter. The aliens invaded the monster reserve known as Monster Island and assumed control of the giant monsters and resident scientists, soon sending them to attack several major cities across the globe, such as NNew York, Moscow, Bejing, London and Paris.Their efforts were finally thwarted by the destruction of their Moon base.

TYRANIDS

The Tyranids are an extragalactic sentient ecosystem of innumerable different species based on the same genetic material dedicated, under a unique hive mind called the Synapse, to survival, propagation and evolutionary advancement originating from an extragalactic from outside the Local Group. They travel across the universe at supraluminal speed in their fleets of gigantic hive ships, systematically consuming all biomatter they meet. All Tyranid organisms in a fleet are synaptic and contribute to a communal Hive Mind.

The components of a Tyranid Hive Fleet travel almost exclusively in large groups known as swarms that possess specialized biomechanical creatures for destroying and consuming a wide variety of prey life forms. Through their invasions, Tyranids acquire new biological traits from other lifeforms, processing these new traits through their reporductive process managed bhy their Norn-Queens. The Tyranids do not build but  use gene-splicing and bioengineering to grow what they need from the organic biomatter harvested from the planets they consume.

It is believed that tyranid advanced parties will scout the Milky Way around the 35th millenium leading several hives behind them around the 41st millenium from different directions.

PAIRANS

Planet of Origin: Paira, a planet on the same orbit as Earth but on the opposite side of the sun

The pairans are a pacific sentient non-humanoid species which developed an advanced civilisation capable of interplanetary space travel millenia ago and have been watching Earth for 4000 years. They look like 2 meters tall starfishes standing up on their 2 bottom legs and using their 2 middle legs for manipulation. A giant eye at the center of their body serves as their main sensory organ.

Pairan technology allows them to transmutate into another lifeform, a technique they used with humanity when they made contact with selected humans in 1956 to warn mankind of the danger of Planet R, a comet on collision course with our own as well as of the nulcear research, mainly the development of Urium 101, a substance much more powerful than regualr radioactive elements.The comet was finally destroyed thanks to the use of Urium 101 and the Pairans returned to their homeworld.
