Leviathan

Designated ID: Anomaly 482-59-6
Short ID: 482-D
Often Referred to As: Many of the scientist studying 482-D will often refer to him as "Leviathan" as a short-name. Newer inductees into the research pool and a few scientists who have been studying him for quite some time will affectionately refer to him as "D" or Levi (lev-ee).
Race: Unknown
Age: Unknown
Birthday: Unknown, best guess says Leviathan is a few thousand years old, but no one really knows for sure.
Gender: Was previously thought to be a male specimen, though has also shown female reproductive traits. Seems as though they can switch sex at will / as necessary. Leviathan has no preferences for pronouns, and is often referred by others as "He" or "It" more often than not.
Sexuality: Seemingly no preference for its partners; As Leviathan can change sex seemingly at will, it really has no preference either way, so long as reproduction occurs successfully.

Intelligence: Unknown. It has, however, evaded multiple groups of scientists sent out to study it, so... Scientists are currently unsure whether Leviathan has the intelligence of, say, a snotty ferret or something more akin to a human, if not even more intelligent. It's really unknown at this point.

Voice: Unsure if Leviathan has a voice that is not animalistic. If it does, it has yet to use such a voice to communicate with humans. Its true voice is near deafening to humans even at a great distance... best to wear ear protection.
Eyes: Two sets, the larger set closer to the base of the nose, while the smaller set sits behind. Deep near-black green scleras, bright green irises, seemingly no pupils to be observed. Double eyelid on both eyes. It is currently unknown whether either of these eyes is primary or secondary specifically, and if the secondary set has any specific use aside from sight.
Length: Compared to a 6 foot human (subject to change)
Body Type: Long, lithe, appears more serpent like in nature if it weren't for the legs. Has two sets of legs more akin to something mammalian, save the lack of fur, and two sets of six legs more akin to something like a giant insect, though again, texture is different and more aquatic based. The use of these secondary insect-like appendages has yet to be determined aside from aiding in movement. Leviathan has ear shells, several sets of horns, fins, and a large tail that it seems to use as a weapon.
NSFW: Leviathan has been shown to be able to change sex at will, much like some species of fish. Has a cloaca.
Skin: Green hues, ranging from darker and more blue toned to brighter and more green toned.
Marks: Dark colored stripes line the entirety of Leviathan's back from the neck to the tail, and various little bright green dots are spattered all over their body; These are assumed to be bioluminescent, as are their fins, claws, eyes, inner mouth, tips of their horns, and the tip of their tail blades.

Extra: Bioluminescent neon green blood

Has been observed, once, to use something like a bat sonar to detect prey, though scientists are unsure why, given its abilities with natural sight.

Personality: Leviathan has been observed few times in this regard, as studies of the specimen remain focused more on anatomy than attitude. However, it can be noted that Leviathan seems curious, but seemingly ultimately a touch lazy. However, when something new presents itself as a stimuli for Leviathan, the specimen seems more than happy to jump into 'play' mode; This was observed readily with the first two scientific parties to try to physically examine Levi; However, Levi is either easily bored or highly intelligent, as they quickly stopped trying to cause mischief and mayhem for the scientists after the third party and onward came to observe it. It seems like Leviathan is a bit greedy and more likely to be enticed with food or toys than anything else, though it is naturally quite difficult to transport anything large enough to lure the specimen out of hiding.
Temper: Unknown - It's an understood that no scientist, or group of scientists, should try to earn Leviathan's ire, even for studying, It is unknown the true extent of the specimen's anatomy, abilities, or attitude.
Mannerisms: Lying around lazily, Playing with whales, Blowing large bubbles, Rolling around in snow
Likes: Meat, New stimuli, Glowing lights, Causing mischief, The deep ocean
Dislikes: Getting bored, Weapons, Being hurt, Loud noises (mainly those created by humans, anything unnatural), Losing its habitat
Phobias / Fears: Seems to have a fear of weapons; The specimen seems to have an understanding of what some weapons are or look like, which is a bit puzzling - more research is to be done on this topic at a later, unspecified date.
Vices: Curiosity, Mischief
Hobbies: Naps

Residence: Lives down in the Antarctic circle for the majority of the year it seems, apparently living beneath the ice in some unknown location (Lives in an underground labyrinth of ice caverns), though has, once every 5-7 years, been seen traveling across the globe on various routes and eventually ending up in the Arctic; The specimen will take the same trail back to its Antarctic home within the next 6-8 months.
Diet: Seems mainly carnivorous from what can be observed; While Leviathan seems to eat whatever it can get its hands on when necessary, it has an obvious preference for meat; Seems to have a preference for whales and large seals.
