SCP-073, also known as "Cain," is a humanoid entity that appears to be of Middle Eastern descent. It has a unique ability that causes any damage inflicted upon it to be reflected back to the source. This means that if someone tries to harm SCP-073, they will experience the same injury instead. The entity is also resistant to most forms of physical harm and has a calm demeanor. SCP-073 possesses a vast knowledge of various languages and cultures, making it an interesting subject for research. It is often cooperative with personnel, but it is important to handle it with care due to its reflective abilities. The entity is also known to have a connection to SCP-076, another humanoid entity with a complex history.
