r/FanTheories
RDJ's Comic-Con line "New mask. Same task." may be Marvel's thesis for Doom: Tony died so his family could live; Victor bends reality so his can.

Theory Briefing
- RDJ's debut line as Doom — "New mask. Same task" — frames Victor as Tony Stark's dark mirror: same protective instinct, opposite choice.
- The fan theory argues Doomsday opens on Battleworld after Doom has already won, using non-linear storytelling to hide the real plot from trailers.
- Doom's rumoured dead wife and child give him a personal stake: he isn't destroying the multiverse, he's trying to stop it dying again.
- A leaked masked figure called "Boris" is speculated to be Doctor Strange voluntarily siding with Doom — echoing his Secret Wars role as Doom's right hand.
- The theory traces a causal chain from Tony's Endgame snap through Loki's TVA collapse to the incursions, making Endgame itself the root of Doomsday.
