((Kinda had idea around an SCP type creature.))

Known Name(s): Cosmo, Cosmic Void, Crypt-Void, Shadow, Stalker, Mythic-Void
Species: Shadow Beast
Class: Mythical Legend
Appearance: Creature is canine in appearance with deep purple fur, lighter purple trails along the back. Creature is eyeless with snake like head and one forked tongue. The creature moves on all four but has hand like front "paws" it uses to grab things. Does not appear to be able to walk bipedal. The creature has six pink/purple "beads" along its muzzle presumed to be its nose but it is unclear.
Gender: Assumed male
Known powers/abilities: Creature seems to be able to use the shadows to its advantage by disappearing into it completely. It can also vanish into other's shadows and move like that to other shadows. Using any light source seems to cause the creature to vanish completely from sight though it still is very much there and can attack or move things. It is believed that the creature can entrall/corrupt or control others but it is currently unknown how it does this. It is also known that the creature can devour the shadows of others thus killing them. The victim's that had their shadows consumed will not have shadows no matter what light is shined on them.
Other Details: The creature seems parasitic in nature and uses living hosts to do things and/or possibly feed off. The creature can only be seen in total darkness, even using technology to attempt to see it in the dark does not work. Only visible with the naked eye.
