In Warhammer 40,000, the Doom Slayer would likely retain his signature arsenal, which operates similarly to high-tier, specialized Imperial relic weapons, notably used for devastating Daemons of Chaos. His loadout would include the Super Shotgun, Crucible Blade, Plasma Rifle, and the BFG 9000, functioning effectively like a one-man Grey Knight terminator. The Grey Knights & Kaldor Draigo: Warhammer's closest equivalent to the Doom Slayer is Kaldor Draigo, the Supreme Grand Master of the Grey Knights. Like the Slayer, Draigo is trapped in a realm of chaos (the Warp), where he has fought endless tides of demons for centuries alone. The Chaos Gods: Debates often center on how the Ruinous Powers would react to him. Many fans believe Khorne (the God of Blood and War) would be fascinated by the Slayer’s eternal rage, potentially leading to a stalemate or the Slayer becoming an unstoppable "blank" that the Chaos Gods would fear. Power Scaling: In lore, the Doom Slayer is a demi-god who draws strength from his fallen foes and has defeated universe-level threats like the Icon of Sin and Davoth. This often puts him well above a standard Space Marine and potentially on par with a Primarch or the God-Emperor of Mankind. Resistance to Corruption: Unlike many in the 40k universe, the Slayer is generally considered immune to Chaos corruption due to his pure, singular focus on destruction, making him a unique threat to the Warp. The Doom Slayer is frequently compared to the warriors of Warhammer 40,000 due to his relentless crusade against demonic forces, leading to a massive overlap in fan theories, crossovers, and power-scaling debates. While not an official part of the 40k universe, fans often describe him as a "Space Marine's power fantasy" because of his god-like strength and incorruptibility.
