SCP-073

SCP-072, known by the alias "Cain" is a  Euclid-class, Cyborg-esque SCP residing within Site 17 of the SCP Foundation.

Description
SCP-073 is a male, cyborg-like entity whose arms, legs, spine, and shoulders are replaced entirely with an unknown metal. On its forehead is a mysterious symbol of Sumerian origin; when asked about the symbol, SCP-073 will become hestiate and refuse to answer. Besides these, SCP-073 behaves like a normal human-being, living in a cell complete with everyday furnishings and eating and drinking regularly, thought it requires a carnivorous diet.

When SCP-073 is attacked, any damge it substains recoils back on its attacker whilst leaving SCP-073 unharmed, likely a property obtained from its metal composition. As a result, tests to retrieve tissue samples prove fruitless.

Any soil-based life (for example plants) within a 20 meter radius of SCP-073 gradually begins to die. If it standson grass, it starts to become barren, leaving nothing but empty dirt and rock. Meanwhile if SCP-073 touches materials derived from plants (e.g. paper, wood, etc.), it begins to rot or disintegrate.

Personality
SCP-073 is described as being polite and helpful amongst SIte 17 personel, although his tone of speech sounds opposite, often cold and mechanical. Unlike most SCPs, SCP-073 is allowed to freely roam inside Site 17, and as a result, often helps out many Foundation staff.
