Superman's speed and power vastly exceed what the Doom Slayer has ever faced, despite the Slayer's unkillable reputation.
The Doom Slayer is arguably gaming's most relentless combatant. Enhanced by the Divinity Machine, he has spent eons ripping and tearing through Hell's legions, killing the Dark Lord himself, and facing cosmic-level demonic threats without ever falling. His arsenal โ the BFG 9000, Crucible Blade, and Sentinel armor โ is designed to destroy beings far beyond mortal capability. The lore establishes him as an entity that Hell itself fears.
Superman, however, operates at a fundamentally higher power tier. Kal-El can move faster than light, tank supernovas, and project enough force to shatter planets. The Doom Slayer's most impressive enemies โ the Titans, the Icon of Sin, the Dark Lord โ are powerful within the DOOM universe but do not approach the scale of threats Superman faces casually.
The Doom Slayer's greatest asset is his indomitable will and refusal to die. The Divinity Machine made him virtually immortal, and his rage fuels an endless fighting drive. But Superman's speed advantage is the critical factor. The Slayer is fast by human and demon standards, but he cannot track or react to faster-than-light movement. Superman could end this fight in microseconds if he chose to.
The BFG 9000 and Crucible Blade are devastating weapons, but they require the Slayer to actually hit his target. Against someone who can cross continents in the blink of an eye, landing those shots becomes nearly impossible.
The Doom Slayer was made immortal by the Divinity Machine and has spent eons fighting cosmic-level demonic threats. He killed the Dark Lord of Hell itself and possesses weapons like the BFG 9000 and Crucible Blade designed to destroy god-tier entities. His will is unbreakable, and the lore establishes that nothing can truly stop him. If any weapon in his arsenal connects, it could genuinely hurt Superman.
Superman is faster than light, strong enough to move planets, and has survived attacks from beings like Darkseid who vastly exceed anything in the DOOM universe. His speed alone makes the Doom Slayer's weapons largely irrelevant โ the Slayer cannot hit what he cannot perceive. Superman's heat vision and physical strikes operate at a scale the Doom Slayer has never encountered.
Superman wins through an overwhelming speed and power advantage. The Doom Slayer is unkillable and relentless, but Superman exists in a power tier that the DOOM universe simply does not reach. The Slayer would refuse to stay down, earning grudging respect, but he lacks the speed to land meaningful hits and the raw power to overcome Kryptonian durability.
