This is Slasher... He's a Slasher
It's been like 3 years and I still can't decide if his monster type or name should be Slasher, so it's both now.

~Slasher is a dungeon-dweller, preferring dimly lit places and/or tunnels, catacombs, basically anything abandoned and underground.
~His eyes are always open. Death would be indicated by a lack of eyes. They are made up of a strange, solidified smoke that can also be found in a haze around his shoulders.
~Eats with his stomach mouth (I mean, he doesn't exactly have a face lol)
~Razor-sharp claws/spines on hands and feet. Used for digging and hunting.
~Legs are strong. Used mainly for speed and kicking through ruins.

Nothing else as of yet :U
