According to the "Slayer's Testaments" in the 2016 game, the being known as the "Doom Slayer" has been tormenting Hell and its armies for an eternity, and once "wore the crown of the Night Sentinels" in the "first age". He was given an Argent energy-charged exomantle of controversial design known as the "Praetor Suit" by a rogue demon, who was reviled by his own kind as a traitor called "The Wretch" for aiding the Doom Slayer's bloody cause. Additionally, at some point the "seraphim" further enhanced the Slayer with superhuman strength, durability, and speed.
