What If Doom Slayer Entered Marvel Universe?

What happens when the ultimate demon hunter from DOOM crashes into the Marvel Universe?
In this epic crossover scenario, the Doom Slayer faces Hell on an entirely new scale—Mephisto, Dormammu, Chthon, and Hela all collide with Earth’s Mightiest Heroes in a supernatural war that shatters reality itself.
As demons infiltrate New York and Hell-Lords manipulate the cosmic balance, the Avengers, Doctor Strange, Thor, Iron Man, and Captain America are forced to confront a being who doesn’t negotiate, doesn’t compromise, and doesn’t stop. The Doom Slayer doesn’t fight for balance—he fights for extinction of evil.

This cinematic “What If” story explores:
= Doom Slayer vs Marvel villains
= Doom Slayer meeting the Avengers
= Mephisto erased from existence
= Dormammu’s Dark Dimension invasion
= Doctor Strange facing an unstoppable force
= A full-scale demonic war in the Marvel Universe

This is not a battle for dominance—it’s a clash of philosophies: absolute justice vs heroic restraint.
