Hell razer

The Hell razer is a new form of demon which appears in the Doom. It could first be spotted from afar, without any explanation offered, in screenshots released shortly after by Bethesda. Unlike the Unwilling and Possessed relationship (in that Unwilling are former humans), Hell Razers do not have anything to do with the Possessed Soldiers they emulate. They are entirely demonic in origin, and appear to be the analog for Possessed Soldiers in the Hell levels.

Codex entries
"The Hell Razer is an astute and tactical foe that will engage enemies from a distance with a powerful beam of unrefined Hell energy. The beam emanates from an arm-like protrusion composed of cartilage and other osseous tissue. Articulation of the cartilage allows the Hell Razer to focus its energy beam into a single charged shot that will obliterate anything standing in its path."
