The Propeller Warwolf

From the wreckage of crashed planes and the infernal hell-refineries came this mutant beast. Twisted together with the remains of war machines, it prowls the battlefields, its propeller spinning endlessly as it tears through anything in its path.

It does not feed on the corpses it leaves behind. It does not rest, retreat or stop. It simply kills until nothing remains — or until it finally dies itself.
