SCP-280 will move slowly towards any human beings and attempt to attack them. SCP-280 appears to sense human life; no limit has yet been found on this ability. SCP-280 will approach to within 14 centimeters of a subject, and then use its hands to pull and tear at the subject, attempting to kill it.The attack can last between one and five minutes, and will continue until the death of the subject, at which point SCP-280 will expose its eyes, lose corporeal form, and move to the next human. If no humans are present, SCP-280 will move and ball up against a wall or other structure until a human being is again present.
SCP-280 will retreat slowly from light, exposing its eyes in the direction of the light, or at any nearby humans. If the area that SCP-280 currently resides in becomes fully illuminated, or there is a very bright burst of light, SCP-280 will fade away and re-appear in another area. This appears to be done purely as a defensive response to light, and will not be used to follow or attack prey. SCP-280 does not appear to eat, breathe, or sleep. It does not ingest any of the tissue removed during an attack, and simply drops it to tear a new piece. Due to its ability to become incorporeal at will, and its aggressive nature, no samples of SCP-280 have been collected.
