Termitan esque

Although this is not the definite design for what the Termitan will look like, it has definitely some aspects. Termitans are recently inspired by the UFO Mythology's Insectoids, Grays, and Reptilians, in that descending order, but originally with notes taken from Biblical Demons and Predator and Xenomorph aliens. They come in many shapes and forms, as one of their best strengths is to splice their soldiers in the womb with DNA of similar creatures (usually arachnids and insects) of the planet they are going to invade, not only to make a specialized soldier but also to make it more adaptable to said planet. Who knows? A termitan soldier class made from splicing with Earth Praying mantis might come in hand offworld, too. 
This particular picture maybe a technomancer type class of sorts. he's wearing armor and somewhat priestly robes, and technotronic membrane. I'm not happy with the over all design but I take note of some of the smaller details for future reference. This is a prototype. This design might be used for a specific class or villain, but not for the average gun and file termitan. 
Altering them in the Queen's womb is a compromise between natural birth born recruits and clones grown in a vat. They utilize cloning from time to time, but unless they are in dire need or have a plan for a specific squad of super soldiers, straight up cloning is rare. This caste based system that controls what caste (soldier, worker, hybrid, etc) in the natural womb of the living queen is called Droning, since it would be the compromise between artificial clones and natural birth born offspring. Civilians are allowed to exist, but as far as having natural family units and reproducing the normal way is heavily regulated and generally frowned upon in their technocratic society. The termitans are logical and almost robotic at times, but often they try to hide that they do have emotions and that pain is partly what inspires them. It would take a lot of them to admit it, though, as they feel they rise above getting sad or hurt.
Originally, there was a race of insectoids that outranked the reptilians, even. The Mantids and Tall long nosed grays and whites actually outrank the Reptilians who serve as the Empire Union's Main warrior class, and as the tall grays gave the short grays as a slave race to the reptilians, the Mantids (who were originally very spiritual and even theocratic) gave the technocratic termitans to the Reptilians to be their air force and cannon fodder of sorts. The reptilians are very mean to the Termitans, because they are SUPER prideful, and feel when they abuse a gray or Termitan they are getting even with the image of their superiors on the galactic totem pole. 
Each race has it's own sub castes. Draconians have their own worker and priest castes as an individual race/sub empire, but as a part of the whole they specialize best in being military. The original Mantids specialize in being diplomats, priests, and scientists, and the grays lab assistants. The Termitans seem to be the Airforce and non combat MOS's to the Reptilians' marine corp, so to speak. Again, each race has their own castes and military branches, but even thought the termitans have marines and navy, in the grand scheme of thing they serve the whole as an airforce. 
This is why Ace and Beaky wonder if the Termitans are a fallen race that is being punished by being put as front line soldiers on conquering earth. Like they disgraced themselves and to regain their honor they have to do a dangerous job that they initially suck at, much to the Reptilians' amusement. Most don't seem happy to be stationed on earth in combat roles. The Scarlet Dominion may  have underestimated Earth's resolve when they casually sent the support classes to the frontlines. 
They are a member faction of the main bad guys, the Scarlet Dominion Imperial Federation or Scarlet Dominion for short. It's an empire (or rather, a centralized but heavy compartmentalized Feudal Union of lesser, petty empires) who have been known to fight amongst themselves. It presents itself as a Federal Monarchy of sorts, giving the impression that each individual Dominion has some autonomy and identity, and implying some constitutional or democratic type government among them. It's a facade. Just like with the People's Republic of Tyranny trope, just because a nation calls itself "The People's Democratic Republic of Kazwhackystan" doesn't mean it's actually all those things. It's probably a communist dictatorship, lol. 
The reason why it calls itself a federation is not a compromise between a democratic confederal type of government and a more unitary Republican type of government, but it's a compromise between decentralized Feudal tyrants and more centralized and Unitary Imperial Fascist tyrants. (like a compromise between Feudal Japan and Imperial Japan...not helping the common man, even if it says it is.) In general the Scarlet Dominion prefers to be a hedgemonic empire, but lately it's been compromised and is getting more directly brutal. 
The Termitan Hex-Mindarchy, A technocratic social Monarchy and hive mind collective that is compartmentalized by shadow fascist oligarchies, is one such lesser empire in the "federation" or "fuedalration" as Beaky calls it. It's a colonial empire and can practice fuedalism, but in a Corporate and scientific sense. As in the government could be unitary but the economy is run by a NeoFuedal Corporatocracy and science by a feudal technocracy. Basically the shadow government fascist oligarchies and the NeoFeudal Corporatocracy and Fuedal Technocracies are safe gaurds by the over all government to keep the empire union intertwined while giving the false illusion of sovereignty.
The only reason why Imperial Federation (or Empire Union) allows different kinds of government in it's different vassals is not to respect sovereignty, but to experiment. One sub empire maybe communist, one maybe more corporate or feudal, one maybe fascist, many having traits of all of the above. But the only reason they allow differences is because they know that different beings are better controlled different ways, and are practicing for what they will use on the humans to control and perhaps exterminate them. 
The termitans are kind of a garbage bin/love child race of the universe, mean't to rival and if need be replace humans as the Imperial middle class of sorts in the universe. 

It is rumored they originally started out as a planet of various insects, arachnids, and crustaceans who were all evolving at the same rate and were becoming a multifaceted society. As in not just ants were in a colony, not just ants, hornets, and other hexopods were in the colony under the same queen or queens, but even distant insects and arachnids were working as part of a collective, usually a hive minded social monarchy.  It is then thought that Scarlet Dominion showed up, mutated them into monstrous slaves to control them and utilize them as scientists and soldiers, a sort of airforce of the greater empire. Pure bred, natural, or "regular" Termitans are a rarity. 
Others have stated that the Dominion created them from the getgo using genetic templates from reptilian, insectoid, gray, and human races. We may never know.
