Item #: SCP-5038
Object Class: Euclid
Special Containment Procedures:
SCP-5038
Description:
SCP-5038 is a vaguely humanoid-like creature that can only appear behind the back of any living creature in it's containment, preferably the largest possible. If this entity is exposed to such living creature, or SCP-5038-1, for a prolonged amount of time, it will begin to absorb it's energy and start to grow in size. SCP-5038-1 will start to feel dizzy, disoriented, and exhausted as the process continues. After approximately ██ hours, SCP-5038-1 will completely run out of energy, and die, becoming SCP-5038-2. SCP-5038-2 will then enter an accelerated rotting state, completely decomposing after approximately █ to █ hours. After SCP-5038 is done with it's prey, it will then continue wail in a high-pitched manner for about ██ hours until it has used up all of it's energy and will slowly shrink back to normal size.
