This artwork depicts the Slayer from Doom The Dark Ages: Revelations as an occult spectral soldier inspired by Doom 3.
Compared to the previous TDA Cerberus Slayer that focused on defense, and Revelations' Elysian Slayer that focused on mobility, this Revelations' Stygian Slayer focuses on stealth.

Not conventional stealth however, of hiding in cover and attacking enemies without being detected, but mid-combat stealth of managing one's visibility as a separate meter akin to Doom's traditional resources of health, armor, and ammo. This is alluded to by the classic Blur Artifact (blur sphere) in Doomguy's gauntlet, as well as his skull directly based on the Invisibility powerup from Doom 3.
He also carries the infamous Doom 3 shotgun, which has an added axe mod based on a concept melee weapon from The Dark Ages: Revelations:
