The Tony Stark star posted a clip of himself listening to his son Indio Downey’s music. And as the camera pans, two Marvel comics come into shot. One of them is Secret Wars and the other is Iron Man: Legacy of Doom, with the latter featuring Iron Man battling Doctor Doom.

Understandably, fans went wild in the comments, with the top one receiving over 3,700 likes. It reads: “Iron Man vs Doom!?!!! How !! New version!!!” By “new version” they mean a Tony Stark variant from another universe, as the Earth-616 Iron Man sacrificially died in Avengers Endgame and Marvel will not undo his death.

Avengers Doomsday hits UK cinemas Christmas 2026 and Avengers Secret Wars follows Christmas 2027.
