Description: SCP-017 appears as a vaguely humanoid figure, approximately 2' 6" in height (76 cm), and bearing a anatomical resemblance somewhat to that of a small child. 017 is completely pitch black over the course of its "body" with no discernible facial features, ears, eyes, genitals, or other identifying marks or characteristics. The entirety of 017's "body" is shrouded additionally in a shifting and smoke-like form of shadow, wavering over his body in the same way that an object at long distances in a desert is obscurred by refraction. SCP-017's reaction to shadows within the confines of the room (which remain the known limits to his senses) is immediate and swift. 017 leaps at the object and only requires the slightest and briefest contact in order to effect it. The object touched is quickly enveloped in a shadowy substance identical to the substance surrounding (compromising?) 017's body and dissolves instantaneously into nothingness. No trace of the object remains after dissolution and 017 returns to its preferred spot in the corner of the room after any objects casting shadows have been destroyed.
