The Kidna'i, an alien race created for Imperium Universalis in the Imperium Offtopicum forums.
Seen on the left: The Kidna'i are insectoid, tall, lean creatures wih reptilian eyes. They appear to be masculine, given their deep voices and ample musculature. They have the ability to reproduce due to being able to produce genetic material from what we'd consider the two sexes. They seem stronger than many because their planet's gravity is several times that of Earth's.
What is most peculiar is their feeding habits. Dreadlock-like tentacle appendages hang from their heads, usually about eight. While their mouths open and close, they appear to be defunct; they feed by stabbing their prey with the dreadlocks' sharp ends and sucking the prey dry from the inside like a spider. This absorption process sometimes increases their prowess in a particular talent or skill, based on what the prey had...
Their mouth likewise no longer secretes venom - their fist-spikes are actually fangs. Don't get on the business end of those!
There used to be two races on the Kidna'gun, the Kidna'i homeworld, in a time long since forgotten.
On the right: The Kidna'i defeated this race and systematically absorbed them, and as such, are able to contort their bodies into a less menacing, some would say almost adorable/attractive version of themselves.
What would happen if the Kidna'i encountered more sentient races, however...? Would they, perhaps, be able to hyperevolve themselves and become the closest thing to perfection the galaxy has ever known?

The Kidna'i are obviously inspired by Cell from DBZ and the echidnas from Sonic.
