Marauder

The marauder is a new monster which occurs in Doom Eternal. It is a humanoid demon with a skull-like head bearing large, prominent horns. It has blueish-gray skin and wears green armor which closely resembles the Praetor suit. It keeps a garland of skulls around its left thigh, indicating that it may act as a headhunter. It wields a super shotgun and an Argent double-bladed battle axe.

Pre-release
Hugo Martin promised at the 2018 convention that there is a story reason behind the appearance of the marauder and its resemblence to the Doom Slayer which will be revealed in the game.
