Hell Spawn

The succubus type enemies diablo.gamepedia.com/Succubus_… from the first Diablo are some of the most infamous enemies from the franchise, be it for their looks or the fact they're incredibly annoying.

This is my interpretation of what they look like up close. Most probably imagine them with ordinary boring human faces, but this approach was more interesting to me.
