Info needed for future Terminator Parody

So as you guys probably know if you read my introductory thread, I was going to work on some films once Hytale Beta is out. So a question I have is what creature in Hytale is the closest to an Enderman from Minecraft or the Terminator in, well, Terminator. The parody will be Lower End PG13 (its such a broad rating, covering stuff that is almost R and stuff that is PG)

As far as I am aware, there is no creature like that confirmed yet. I am sure that with your own custom mob or maybe even a cinema tool you can find a possible replacement.
