Special Containment Procedures: As of The Escape of 15-07-████, SCP-XXXX is to be contained behind two layers of 0,75 meters of titanium alloy, insulated with a 0,30 meter layer vermiculite in between, while submerged in solid mercury. The chamber contents are to be kept at a constant temperature of 0 kelvin, to keep SCP-XXXX held in place for as long as possible should containment be temporarily compromised in any way. In case of containment failure, heavy explosives are to be utilized to temporarily disable SCP-XXXX, till special forces can arrive on scene. SCP-XXXX is temporarily contained at site-19, as of 28-██-████.
Description: SCP-XXXX is a genetically engineered and artificially bred bipedal humanoid mutant, at the █████ ██ ██████ research facility as a product of the ███████████ project. It stands at 2,59 meters in a natural posture and weighs between 259-315 kilos when mobile, depending on its state of regeneration and recovery. SCP-XXXX posses physical and genetic traits of the following organisms: "Homosapien, Canis Lupus, Canis Lupus Familiaris, Chiroptera, Corallus Caninus, Mantodea, Asterias Rubens, Dynastinae, Heterometrus Swammerdami and Deinonychus". CSP-XXXX has tall and thin ears, covered with a thin layer of fur. It has luminescent yellow eyes buried relatively deep into it's skull. SCP-XXXX's mouth is covered in jagged teeth, of which the canines is estimated to measure 15,35 centimeters, rendering it unable to completely close its mouth. The head, torso and upper thigh are covered in skin and fur, resembling that of a wolf, while the raptorial, legs resembling that of a minatis, and metasoma are exposed exoskeleton. Despite only parts of the exoskeleton being visible, it was observed during the recapture of SCP-XXXX, due to several cavities in its body as an effect of heavy explosives, that the skin covers a layer of exoskeleton. The raptorial legs are estimated to measure 2,19 meters when fully extended, while the metasoma is estimated to measure 2,41 meters. The legs and feet resemble that of deinonychus, with a pedal ungual estimated to measure 15,49 centimeters.
Attributes of SCP-XXXX:
- SCP-XXXX's sencory hearing is beyond that of any organism known to man as it was observed, via an acid resistant tracker inserted into SCP-XXXX early in its fetal period, during The Escape of 15-07-████. The tracker displayed movements matching that of a predatory animal's, towards the recontainment-squads, at a distance of 1,9 kilometers.
- SCP-XXXX's luminescent eyes can capture heat radiation/infrared radiation from its prey, giving it heat vision.
- SCP-XXXX's sencory smell is compareable to that of a shark smelling blood in the ocean.
- SCP-XXXX's exoskeleton is stronger than any material currently known to and understood by man. It is estimated to be 16-17 times stronger than tungsten, rendering bullets of any caliber practically insufficient. Heavy explosives are to be utilized when engaging SCP-XXXX.
- SCP-XXXX's strength in relation to mass is comparable to that of a rhinoceros beetle. This strength combined with the material strength of the exoskeleton, as observed in The Escape of 15-07-████, enabled SCP-XXXX to cut through 0,93 meters of stainless steel in a single strike.
- SCP-XXXX has been observed, via a tracker, to run up to 90 kilometers an hour, during The Escape of 15-07-████, when approaching the recontainment-squad.
- SCP-XXXX's telon contains an unknown ascitic venom, estimated to be capable of killing up 189 blue whales in a single dose (200-250 ml). A relatively high concentration of this asictic venom is also present in SCP-XXXX's blood, as observed by lethal wounding during The Escape of 15-07-████, rendering SCP-XXXX poisonous and even more dangerous when wounded.
- SCP-XXXX's extraordinary regenerative capability extends far beyond that of any known starfish and sea cucumber. Not only can it regenerate more, but also at a much greater rate. SCP-XXXX was reduced to little more than an empty exoskeleton as a result of heavy bombardment, yet was able to regenerate and recover much faster than it could be contained, forcing the SCP foundation to bombard it continuously for approximately 43 minutes, till construction and engineering crew arrived to construct a temporary containment facility. This regeneration also renders SCP-XXXX immortal, as it allows the repair of sprawling and damaged DNA.
Behavioral Patterns of SCP-XXXX (As observed during The Escape of 15-07-████):
SCP-XXXX often exhibits a mixture of reptilian predatory and human playful behavior. It stalks its prey from afar and circles it, much like a shark. While doing so it never removes its gaze from its target with an almost gyroscopic precision. Eventually SCP-XXXX will approach its prey with a speed of up to 20 kilometers an hour, while being practically inaudible. When within close range of the target, yet not spotted, SCP-XXXX will stand and stare at the prey, waiting patiently for the target to move, at which point it strikes, while bursting into a laugh/scream resembling that of an enormous hyena. SCP-XXXX does however have some predatory flaws. It's excitement when approaching a potential prey causes it's toes to twitch forcing its pedal ungual to come into contact with the ground at a random rate, making a very distinct tapping. Furthermore, SCP-XXXX has a tendency to enjoy hunting, so much so that it often leaves prey only to hunt it again, as long as the prey does not move nor show any sign of being aware of SCP-XXXX's precense when in close proximity. This behavior is why SCP-XXXX is often addressed as: "The Stalker".
