SCP-076-2 Abel

Terminating SCP-076-2 is highly problematic due to its impressive physical abilities. The subject possesses superhuman strength and speed and, while not invulnerable, demonstrates the ability to ignore pain and shock, continuing even with what would be debilitating injuries in a normal human. Previous events involving SCP-076-2 have demonstrated that the object possesses the ability to (among other things):
To shatter a steel security door over four (4) minutes of repeated attacks.
To travel a distance of 64 m in less than three (3) seconds.
To receive several .50 caliber BMG bullets to the head and survive for several minutes, continuing to kill even with severe damage to the cerebellum.
To strike and deflect bullets from pistols and rifles in mid-air using a piece of steel rebar.
Survive up to one (1) hour without oxygen, before suffocating.
SCP-076-2's most unusual ability, however, is the capacity to materialize bladed weapons seemingly out of thin air. Slow-motion recordings reveal that the blades in question are drawn from a small dimensional rift described as "a small hole in space." The destination of this portal is unknown, as is the source of SCP-076-2's ability to create these rifts. In images, these weapons appear to be made of a completely opaque black material, similar to a "black vacuum in space." Since the blades disappear rapidly after leaving the Subject's possession, no structural analysis has been possible to date. The Subject is also multilingual, speaking all languages, even dead languages; when conscious, it is common to see him speaking Sumerian (though this is quite rare).

SCP-076-2 resembles a lean, male human of Semitic origin, approximately twenty years old. His hair is black, his eyes are gray, and his skin has an olive tone. The individual is 1.96 m tall and weighs 81.65 kg. His body is covered in numerous tattoos depicting arcane and occult iconography (mostly in the form of demonic faces), ranging from subtle to overtly ostentatious. When located inside SCP-076-1, the individual is technically dead.
However, occasionally SCP-076-2 awakens, effectively undergoing a complete "reanimation" process, with all the vital signs necessary to keep a human being alive. The Subject will then attempt to exit SCP-076-1. If successful, the Subject enters a trance-like state, seeking out the nearest human and ignoring any other living being in the process. Upon contact with living humans, SCP-076-2 enters a state of rage in which it attempts to confront and kill all individuals encountered. To date, only the Subject's death has proven capable of ending this violence.

Description: SCP-076 consists of two components: a stone cube (SCP-076-1) and a humanoid entity contained within it (SCP-076-2).
SCP-076-1 is a 3 m cube made of a black, veined metamorphic rock. All external and internal surfaces of SCP-076-1 are covered with patterns deeply etched into the stone, bearing no correspondence to any known civilization. Radioisotopic analyses indicate that the object is approximately ten thousand (10,000) years old. There is a door on one side, sealed with a 0.5 m lock, surrounded by twenty (20) smaller locks in a circular arrangement. To date, none of the keys have been found, making the door impossible to lock.
The interior temperature is approximately 93 Kelvin, and is not altered by any means, internal or external. Directly in the center of this chamber lies a stone coffin 2.13 meters tall, held in place and sealed by several chains of unknown origin and material, attached to the inner edges of SCP-076-1.
