New (possible horror like) enemy

[Vanra]

So, I had something in mind for an enemy. I want to work it out as well as work on the mod itself with anyone willing to help me (considering I'm a bit new to Lua still.)

What I had in mind is an enemy that isn't interested in actually the survival of the planet but rather doing it to torment you.
Don't have a name for it yet, kinda still working it out, but any advice would be welcome.

The creature I pictured would be pitch black with small glowing red eyes, pretty much invisible in the dark. They would live in mostly dark places, like the forest that haven't been cut down yet. Large in number, even though at the beginning they would just be one or two walking around. They don't come out during the day, not having any bases either, living in the shadows of the trees. The more forest you destroy, the more will appear. They can also appear whenever they want, since when their eyes are closed, they are completely invisible in the night.

They would start out of just curiosity, when not a lot of trees have been cut down yet. But when more have been cut down, they will come and attack anything that consumes fuel or generates electricity. Once the lights are out, they will torment you as long as the night lasts, attacking you and destroying things.

That's about as far as I got, if you feel like adding anything, most welcome.
