What if Avengers Doomsday’s Dr Doom sets place where Tony Stark isn’t able to get back to earth after blowing up the Chitauri mothership—giving him the scar he has on his face?
(And of course this is in a different universe/reality but there is always America Chavez who can travel around the multiverse…)
(He also somehow he dawns the name Victor von Doom)
(He also wants Franklin Richards to warp reality to fit his will which we don’t know yet…)
