If there is any word that could describe a Gorgas, it is dragon, or dragon-like. They are huge muscular reptiles with six limbs, a pair of legs, and two pairs of arms with the back pair being modified as powerful wings. Their tails are twice as long as their torso, and they have a medium sized yet flexible neck, with a narrow saurian head. Some variations may have a sort of beak instead of a snout. Their tails often have 'organic spears' with keratin-like material for a sharp tip of their tail.
While their is no distinct differences between males and females, each individual can have a wide variety of differences. The most noticeable unique features one could have are the size, shapes, positions, and amount of horns on a head, any sort of spine or scutes along the back/spine, frill variation or lack of frills, size, and a variety of colors for their scales and eyes.
The average sizes for a Gorgas range between 9 feet tall, to 18 feet tall, and 805 lbs to 1,349 lbs. They seem to have a potentially indefinite lifespan as their cells do not seem to age past their maturity state, nor do they seem to get any hindrance with older ages, in fact they seem to only get better as they age. Like most other reptiles they do not stop growing, rather their growth rate shrinks overtime. In theory a Gorgas that lives long enough could very well exceed the own average height of its species. However rarely do any exceed 400 years in age due to their violent nature, disease, and other factors. They also take a very long time to mature due to their long life, it takes about 100 years or more for an infant to mature, one of the many reasons as to why they have a relatively low population.
They and many other reptilian species of their home world have what seems to be an indefinite heat resistance. It seems very much impossible to burn, melt, incinerate, disintegrate, or damage a Gorgas by any method of extreme temperature alone, even plasma, molten rock, and other factors of such extreme temperatures seem to do next to nothing to them. However this immunity leaves to some misconceptions. They are still vulnerable to explosive forces from many heat-related weapons, theoretically while dropping a Gorgas into the sun the heat wouldn't kill them, they'd still die instantly from the intense gravity, lack of oxygen, and the likes. While they are remarkable resistant to acids and bases they can still be broken down or eroded by powerful chemicals, they just can't receive 'chemical burns'. However due to their adaptability to extreme environmental heat and their cold-blooded nature, they struggle with cold temperatures. Even in room temperature a Gorgas will become 'chilly' and uncomfortable, becoming less efficient and active in such conditions. Anything below room temperature however, is potentially fatal to a Gorgas without proper protection. Cryogenic weaponry would be especially effective against them.
They are also incredibly strong, the average Gorgas can easily lift 2/3's of a ton, and there have been records of those who can carry over a single ton of weight. Most Gorgas's can break through steel walls if they are not fortified enough granted with some struggle on their part. Even their jaws and teeth can bend an iron bar. In terms of speed, they can run up to 25 miles per hour on average, and can run for 3 miles in distance. In flight they are slower, 15 mph and can only fly for about half a mile. their tough claws can dig into tough materials such as weaker metals, wood, and stone, and they have been known to scale walls and ceilings in this matter as it is stealthier then flying.
Despite their heavy bodies The wings of the Gorgas are just as strong as their other two arms, and can allow sustained flight in gravity that is around earth's level.
Most of their scales and their skeletal structure is as durable as stainless steel, and has a similar metallic texture despite its organic nature. The only exception to their scales is the paler, smoother scales that run along their chests and underparts of their body and limbs such as beneath the tail and skin membrane of their wings, essentially being weak spots in their natural armor. Even still though, they are stubborn creatures with great will power and strong bodies.
Their most remarkable ability however is their ability to breathe fire. Essentially each Gorgas is a walking flamethrower. They have a specialized organ sac within their throat that can secrete a flammable chemical produced through biochemical methods. Their forked tongues and the line of their lips are tipped with a carbon bio-structure that when they flick against each other in a certain and quick motion, it creates sparks similar to when striking flint and steel. By creating these sparks they can ignite the released gas, and can create jets of flames from within their throats that can be spewed out for a distance of over 9 meters, and can sustain such a breath weapon for as long as a minute. They are however, briefly vulnerable as they cannot breath in oxygen while spewing out flames, so they become exhausted for a few moments after using their fire. Additionally, it takes a few minutes for the bio-gas to build back up in their specialized organ.
Their eyes produce a faint bio-illumination, that is often described as dim candle flames when viewed in low lighting or in darkness. Like snakes and lizards, their forked tongues are great at tracking and narrowing down scent trails from over 3 miles away. Wounds can naturally heal much faster then many other life forms, as a large gash, dented scales, broken bones, and other such injuries can be healed naturally a little over 2 weeks, a process that is aided by the fact that they shed and regrow new sets of scales and teeth within a week. Their cells remarkably can also regenerate almost any internal organ except for the brain, and can even regenerate limbs. However it takes a very long time to regrow a limb or tail back, 50 years being the minimum. They cannot come back from death either, while they can potentially recover from most fatal wounds they would still need advanced medical treatment to keep them stable enough to allow their natural recovery. They due have a relatively high immunity for diseases, but they are certainly not immune to diseases, especially foreign ailments.
Ironically, due to their size it is difficult for them to operate foreign weaponry, tools, and machinery. While their hands are opposable they have large, clawed fingers and only have 4 digits instead of five. Their conscience is far more primitive then the more advanced alien and human species, but they are still sapient and can speak well, some have been remarkably wise.
