Per 
Description: It is often seen humanoid, in the form of a 20-24 aged man. It has two forms: human and bone. It isn't picky in its human form,but only consumes organic matter in its "bone" form,example as humans. It had a conflict with SCP-682 in a containment breach. It once came in contact with SCP-999, leading to its happiness. SCP-049 is weirdly interested in its "bone" form, as it is made of unknown and tough material. It turns human when 50% of its body comes in contact with any form of light, ultraviolet light, infrared and sunlight. Its aggressive level increases as the contact with light decreases.
There is no effect to it when coming in contact with SCP-035, making it immune to psycological effects.
Origin: Unknown
Class: Euclid
