Supernatural Big Bad!!

Leviathans, also called the Old Ones, pre-date the creation of humans and angels, as well as the soul itself. They would also pre-date any beings with souls, such as monsters. They are therefore among the first creations of God. Death describes them as immensely powerful and hungry. Before God went on to create more creatures, however, He felt that the Leviathans threatened to consume and destroy everything 'in God's petri dish'. For this reason, Death states that God created Purgatory and sealed the Leviathans inside to contain them and their hunger. When Castiel opened the door to Purgatory quite recently and took in the power of the souls stored there (to increase his own angelic power), he also took in the Leviathans. With the help of Sam, Dean and Bobby, Castiel finally expels the souls back to Purgatory, but some of the Leviathans "held on". Castiel's Vessel is taken over by the Leviathans, and claim that Castiel is dead and no longer in control. They manage to guide Castiel's vessel into a nearby water catchment just before the vessel disappears in a whirlpool, releasing them into the water supply. The number of Leviathans that escaped from Purgatory is unknown. The Leviathans operate within a hierarchy lead by Dick Roman.[1] Their 'modus operandi' is to take on the forms of humans who have valuable skills, or are in positions that may be useful, particularly positions of power including the military and corporations. Their ultimate goal is not yet known, but they appear to be playing a long game, infiltrating human society and keen not to draw attention to themselves. Dick Roman says their golden rule is "there's no such thing as monsters". They are hunting down the Winchesters, as they perceive them as a threat. The Leviathans have sharp teeth within an expanding jaw, and possess a bifurcated tongue. They feed on human internal organs - sometimes with cheese. They can mimic a particular human being following contact with one, or if they obtain DNA from a person. They are then aware of all that person's thoughts and feelings, and even hallucinations.[2] All the Leviathans now outside Purgatory absorbed everything that Castiel knew, as he was their original vessel. When wounded they "bleed" black goo. Leviathan!Sam said that he once had a brother with many issues, and Leviathan!Sam ate him in the end - so they are not averse to cannibalism. 'Bibbing' was first mentioned by Dick Roman when he told Valente: "Next time, call me with a win. For your sake. Please don't make me bib you."[2] When Dick decides that Dr. Gaines's experiments are drawing too much media attention, he decides to bib him. This involves literally placing a bib on him, and then Dr. Gaines eats himself until nothing is left - except a goo stained bib. So far this is the only known method of eradicating a single Leviathan for good. Sam and Dean refer to them as 'big mouths'. Powers and Abilities Possession: Leviathans can possess any human they come into contact with in their fluid form. This person becomes their physical embodiment of sorts. These shells bleed black ectoplasmic blood when injured and can reshape their jaws to display long sharp teeth and a two-pronged tongue. Shapeshifting: Once a vessel is taken they can reshape it into any human form they touch. They require only a fragment of DNA to transform into a person; even lost hair will do. The creature possessing a little girl takes the form of a doctor by touching his arm. They can also absorb the memories of anyone whose form they take, much like a Shapeshifter, but without requiring the person to remain alive. It is revealed that certain humans like Charlie Bradbury and Bruce Springsteen possess a certain "spark" that means they cannot be copied. Super Strength: They are shown to possess greatly enhanced strength; at their first meeting, they are able to hurl Dean and Bobby across a room with little effort. Healing/Endurance: Leviathans are extremely resilient, surviving multiple shotgun blasts with silver shot, including one to the head at point blank range. One also survived and reassembled itself after being crushed by a falling car. They can even re-attach their heads if decapitated. [1][2] Weaknesses Borax: Leviathans are highly susceptible to materials that contain the chemical compound Borax (Sodium Borate) such as household cleaning products. Contact with their skin results in an instant burning effect that can reduce them to charcoal-like husks if they are exposed to too much. It is suggested that they will eventually heal from the effects, however. Their leader, Dick Roman, may be less susceptible to the chemical.[3] Beheading: Removing a Leviathan's head disables them temporarily. But unless the head is kept far away from the body it will re-attach itself. The combination of burning them with Borax and then beheading them and separating the head and the body appears to be the only way to put them down indefinitely, assuming the head has no way of finding its way back to the body. Witchcraft: Leviathans show susceptibility to witchcraft. It can incapacitate them temporarily. Leviathans on The Loose The first leviathan appearance is when they take over Castiel.
