DOOM OC: Stalker
This heavy demon specializes in ambushing prey from the shadows. It’s carapace armor makes it invulnerable to most attacks, the back of its head is the only part of its body that’s protected by armor. Its mask is made of a less thicker carapace and is the only piece of armor that is not embedded into its body, shooting at its mask enough may overwhelm its mask and cause it to break. Its mandible are extremely delicate so shooting at them will disable it from biting. Beware, this creature can also cloak at will.
