The Undead War Monger

The Undead War Monger, or simply, The War Monger is a humanoid Monster kept in the Facility. He is not listed on the Whiteboard, but can be briefly seen during the System Purge.

Physical Description an Attributes
The (Undead) War Monger appears to be a male humanoid that has possibly either been brought back from the dead for an unknown reason and by an unknown source, or looks so disfigured as to appear undead-esque (due to his lack of coloured irisis, a trait shared by other undead monsters, such as the Deadites, etc). He has something that resembles a plated glove or gauntlet on his left arm and a smaller one on his right arm, he appears to have claws on the ends of his left fingers. He wears a necklace of some kind on his neck, a belt, and he wears a loincloth. He is seen wielding a pipe. There is another monster seen in the behind the scenes video "An Army of Nightmares" that resembles him in appearance. It is currently unknown what that creature is called and what relation, if any, it has to this monster. He closely resembles the Savage with Hatchet in appearance.

The item that summons him is unknown, however it could possibly be some sort of relic or item associated with him in his past life.

Appearances
The only time we catch a glimpse of the Undead War Monger in the film is very briefly during the chaos of the System Purge. As a Wraith flies overhead as a Deadite is about to throw a Facility worker over a railing, he can be seen for a split second, chasing and about to hit another employee with his pipe. This is the only time we see him, but there is an up-close picture of him in the visual companion.

Inspiration
It may have been based on the trope of some horror films where a soldier, warrior, or a figure of history, returns from the dead, such as House from 1986 or Berserker from 1987.
