Still has some work to be done, likely some massive improvements to be made and possibly toning them down a little. These are intended to be the universes "universal bad guys" to be used in an RP, not so much for a players character.

Designation: Hivemind
Homeworld: O'aklo
Language: Telepathic
Average height of adults: 6"7
Skin color: Ranging from pale red to blood red
Hair color: None
Breathes: 70% Sulphur 15% Methane 15% Oxygen
Strengths:
Collective Intelligence: Kha'Veni become more intelligent the more of them there are.
Physical strength: Kha'Veni have incredible physical strength, capable of tearing and eating their way through ship hulls.
Claws: Their long claws aid them in both digging and killing their prey.
Heat Tolerance: Their homeworld is an incredibly hot, hellish place, this allows them to endure and even flourish in temperatures up to 460 Celsius, just above the boiling point of the sulfur in their homeworlds atmosphere
Weaknesses:
Collective Intelligence: A lone Kha'Veni, or even a group of less than 20 or so is little more intelligent than a rabid animal with little regard for self preservation.
Dormant: Kha'Veni will go into a state of hibernation, burrowing into the ground, for years at a time, rendering them completely defenceless.
Cold Intolerance: Anything below a temperature of roughly 230 Celsius will cause Kha'Veni to enter a hibernation state
Distinctions: Their skin resembles exposed muscles and their faces are apparently featureless apart from their large circular, tooth lined, maw. They are ravenous creatures and will attempt to eat anything and everything.
Average Lifespan: 300 Standard Years
Races: All known Kha'Veni are completely indistinguishable from each other
Estimated Population: Unknown, possibly in the Trillions
Diet: Primarily meat, though they will attempt to eat anything.
Communication: Telepathic, incapable of physical speech
Culture: Kha'Veni culture is little known to other races due to their permanent hostility and the utter failure of any attempts at communication. They often inhabit a planet and begin digging out large underground hives from which they will hunt from, once they have consumed most life on a planet they will go into a state of hibernation, waiting for the planet to flourish with life again. There appears to be no form of caste system or social interaction between individual Kha'Veni, all are just a smaller part of a larger organism.
Technology level: Kha'Veni are not particularly technologically advanced, even in greater concentrations, they have been known to inhabit other planets than their homeworld but their method of interstellar travel is unkown. It is presumed they simply stow themselves away on any ship that visits a planet infested with Kha'Veni, causing that ship to unwittingly spread their infestation to countless other worlds.
General behavior: They are incredibly hostile to all other biological life, viewing it as little more than a food source. They will often hide and stalk their prey, able to be incredibly covert about their actions, they can hide away inside a ship for years, never to be discovered until it is too late.
History: [Describe an abridged history.]: The Kha'Veni came from an incredibly hostile world, covered in geysers that spat out hot sulphur into the atmosphere, few things could survive in such a place. They evolved over the years to become the apex predator of their planet, but their numbers were incredibly limited by the scarcity of life on their homeworld. This was until at some point another race presumably investigated their planet, unknowingly spreading them to life-rich worlds that would allow them to reproduce to untold numbers.
Ever since then the Kha'Veni have had only one single minded goal, to spread and consume.
