name : the leviathan. it’s what they prefer to call both themselves, the head, and the entire mass as a whole. this can often get confusing, but considering they were all initially part of the same creature, the leviathan are loathe to deviate from the singular title. gender : without gender. they/them, but in the plural sense. species : cosmic-level, eldritch super-vacuum. visual age : considering they most often take the form of jimmy novak, late 30′s. however, they’ve done a bit of detail alteration to make the body look younger out of personal preference and pride. physical age : the leviathan, if we’re going off season seven of supernatural’s canonical information, was god’s prime creation. they are one of the oldest beings in existence, which would equate their age to being somewhere in the billions. visual size : 5′11″, will get offended if you ask their weight. approximate size : their mass as an entire entity is comparable to the gas giant jupiter, so legitimately around 4,185,699,999,999,999,752,125,022,208 pounds. their length is not determinable in the terms of scientific comprehension but to put it simplistically, they’re deliriously gargantuan. defining features : blue eyes (most of the time), medium-length black hair that ends at about the nape of their neck, an impossibly affluent amount of razor-sharp teeth, black blood. a distinctly slimmer, almost effeminate, body build in comparison to both that of jimmy novak and castiel in season seven; more angular facial features, delicate wrists and a slender waist, somehow leggier. is prone to brief spells of extraneous body parts, primarily eyes and mouths.

appearance : the leviathan have long since ditched the infamous ensemble of the ill-fitting suit and lopsided trench coat and have adopted a style similar to that seen of the leviathan in season seven: suits. however, instead of simply sticking to the (again unflattering) variety of black suits with garish shoulder-pads that appeared in wealth among both the leviathan and angel ranks, the leviathan have chosen to expend their considerable wealth on the best of the best. every suit is tailored to perfection to properly and attractively fit their vessel’s body; they wear every color imaginable as long as it’s fashionable, and you wouldn’t be wrong if you got the impression of unadulterated vanity, because the leviathan are the embodiment of pride to an almost literal sense.

they tend to wear the – basically – perpetual expression of a smug smile, often baring considerably more teeth than necessary. their physical mannerisms are, more often than not, vaguely patronizing and demeaning, as if they were talking to someone of incredible stupidity; their stride is as exaggerated as their dramatic nature, paying homage to their tendency to flaunt in that they saunter rather than simply walk, as if taking every individual opportunity to show themselves off. it’s a gift.

 as of late, they’ll usually be seen sporting a pair of wrist-length leather gloves (a gift) and a single ring, sat on their right middle finger; the ring has a combined concoction of grace from two angels (they won’t say which), and is a very important item to them.

personality : hedonistic in every aspect of the word. overly indulgent, undoubtedly one of the most conceited creatures in existence, and in possession of, undoubtedly, one of the most deafening and large consciousnesses in creation. the leviathan are an egomaniac with a god complex so utterly ingrained into their subconscious that their end goal is to devour god; they are self-praising and will take any opportunity to preen, often going so far as to go on tangents about how much better they are in comparison to their rivals, often while keeping said rivals pinned beneath their shoe like a cowering cur.

 remorselessly violent and sadomasochistic, the leviathan will kill (and torture) without hesitation, spending countless hours leeching the life from their prey in order to satisfy their sick nature, which is a direct result of various factors – prior to being trapped in purgatory and effectively sundered into hundreds of thousands of pieces, the leviathan were among the most peaceful of entities, mindlessly obedient in adhering to their given purpose. now, with a somewhat broken multi-limbed consciousness, the leviathan are a creature lethally unstable and short-tempered, delusional in their perception of their own self-righteousness and, somehow, still doggedly following their god-given purpose while taking nearly every breath to demonize god and creation as a whole.

needless to say, they’re rough around the edges. despite their raging superiority complex, the leviathan are also piteously insecure in some aspects. they shy away from vulnerability unless in a sexual setting (and even then one is hard-pressed to get them to ask for anything coherently) and have abandonment issues, resulting in a high level of need that could be rightfully stressful to any and all partners. they tend to clam up instead of expressing emotion; they despise most forms of platonic and romantic touch as well as expressions of pity or empathy, and are expert in pushing others away while voraciously seeking attention. they’ve recently gotten better in terms of mentality due to the efforts of their saintly mate, and have become considerably softer around the edges, pliant to most forms of positive reinforcement coupled with physicality. they’ve also become fiercely protective and possessive of what they deem “theirs”.

weaknesses : the leviathan are endlessly starving, in the literal sense. they have to consume a large amount of organic matter on a daily basis in order to maintain the slivers of stability they do possess, and to deprive them of that necessity not only weakens them, it drives them insane. after around three or four days deprived of a meal, the leviathan will go into “hibernation”, becoming unresponsive to near everything but the potential for food. as a result of this perpetual voracity, the leviathan are unstable and volatile, and can be misled, confused, or easily bested if they’ve gone some time without sustenance. the less they eat, the closer to “mortal” they are.

borax is acidic to them, but cannot kill them. in large dosages, it can deter them from pursuing someone, but in most cases it only serves to anger them further.

they have a wicked temper, and an even more wicked sense of pride. if you demean them, insult them, or anything of the sort, you can reduce them to a frothing, repulsive congregation of maddened rage. however, this will mostly likely result in your death, so it’s not recommended.

they possess a phobia of fire, and of being incapacitated and there after being threatened with pain or “death”.

cutting off their head will send them to purgatory, from which they no longer have a way to return back to earth unless someone places their head directly near their body or sews it back on for them.

they go through spells of complete and utter unresponsiveness, which often consists of scrabbling at nothing, drooling, babbling, etc. they are vulnerable while in this mostly-catatonic state, though will often seal themselves away in their home if they feel it approaching.

they’re slow. they take a long while to recover after a fight if they’re been considerably injured. 

they are deathly afraid of losing those important to them.

abilities: basically invulnerable and incapable of actual death, if only because there hasn’t been a way to kill them that’s been discovered. possesses cosmic strength more considerable than many creatures in existence, including archangels. they are capable of using the organic energy that they’ve consumed to regenerate their limbs at an astonishingly high pace, though this is an exhaustive process.

they are capable of assuming the complete knowledge and memories of whatever they devour, as well as the appearance of those they devour. as a result, this makes them a very convincing actor, and has aided them in the consumption of countless an individual.

they can create new leviathan. they can “create” new limbs. they can utilize the limbs (including angel wings) of those they’ve consumed.

they can grow consistently at a break-neck pace, and to massive sizes. the bigger they get the more powerful they get, with little repercussion except the sizable blows to their mental state that the continued consumption of human souls results in.

they can appear wherever they wish, though most preferably via the access of a body of water.

they can break bone easily. they can inflict massive amounts of grievous damage easily. they can bite through most metals, and snap most metals. the level of destruction that can inflict is on such a level that to even unravel out of their vessel in its entirety would destabilize (and create a sprawling vacuum) earth. they are not to be trifled with.

overall : the leviathan “hierarchy” works as a systemically branching hive mind, primarily controlled and run by the “head”. imagine a body with hundreds of thousands of limbs; each limb can move independently in different directions, but have limitations depending on the range of motion and the flexibility of the limb. all of these limbs are also controlled by signals sent from the brain, the head, which is the mastermind of the movement that the body undergoes. 

hierarchy : the hive mind is a complex system separated by a series of assumed ranks based on intelligence, amount of independent thought, and power. the head is the most capable of independent movement and thought and is the most intelligent out of the hoard, and is also the most powerful. there are none in the mass that are on the same level as the head, and there will never be any leviathan on the same level as the head, though as soon as the head is “killed” the next highest ranking leviathan must step up to the plate and adapt. as a species highly capable of acclimation to their environment and to the changes in said environment, and a species also adept at evolution, the overreaching success chance of the entirety, although bound to diminish within a short time after the death of the head, will always repair and improve.

there is no name for the ranks of the leviathan and no set logarithm for determining which leviathan will be high-ranking and which will be low-ranking. it is randomized. the highest ranking leviathan after the head is highly intelligent and stronger than the average angel, on par with seraphim. also still tied to the hive mind (as every leviathan is) they are capable of high levels of independent thought and individual personality, and can enact independent actions based on personal perceptions of a situation. they will take human names, and can successfully appear human. they are considered the minds of the machinations of the leviathan operation, and will be kept close to the head. they will travel individually, as they are both powerful and intelligent enough to warrant venturing on their lonesome. they are comfortable without the presence of another leviathan.

the next rank is of higher than average human intelligence, is capable of mostly coherent independent thought, and is stronger than the average angel, but beneath the power level of a seraph. they can perform independent actions based on personal perceptions, but have a limited amount of common sense. they possess quick mental and physiological reaction times, and are considered the eyes and ears of the leviathan operation. they often travel with a partner, or in groups of three depending on what the task is. they receive orders to enact their independent actions from the head or from the rank of leviathan above them.

the average leviathan is next, and this rank is the most abundant in the mass. they are of slightly higher than average human intelligence, and are capable of limited independent thought. they are on par with the average angel. their independent actions can often be confused by the rampant pace of the hive mind, and as such they have slow conscious reaction times. they react mostly by animal and human instinct, and while they are capable of perception, they will often double check with the other leviathan around them to ascertain details. they are the brute force of the leviathan, and work best in small groups; basically, they’re the epitome of a group of highly intelligent dogs. they can be easily misled and startled, and an average leviathan separated from the group is mostly easy pickings for a highly skilled hunter or angel.

the final rank is the lowliest of leviathan, which are primarily pack animals. they are incapable of independent thought, and all action must be spread through-out a massive group, the chosen “pack”. they are incapable of performing most of the basic human functions beyond walking, running, and eating; they are shambling abominations with little thought other than to find prey and eat it, or to adhere to the will of the head. they are characterized by their unblinking eyes and perpetually slack mouths, brimming with shark-like teeth, and will capture their food by swarming the unaware in dark areas and ripping it to shreds alongside the rest of the pack. they are easy to get rid of on their lonesome, but the sprawling mass of lowly leviathan is difficult to clean off, and those that attempt are prone to perish by a sudden amassed onslaught.
