SCP-076
SCP-076 is a humanoid entity known as "Able," who possesses superhuman strength and agility. It is contained within a specially designed facility to prevent its escape. When released, Able exhibits violent behavior and has a strong desire to engage in combat, often resulting in the death of personnel.
The entity is also associated with a mysterious object called SCP-076-2, a stone sarcophagus that appears to be its resting place. When Able is killed, it can regenerate and return to life, making it a significant threat to containment and safety protocols within the SCP Foundation.
