With such a significant revelation on hold, speculation abounds. It seems possible that Doom’s character may remain enigmatic in “Doomsday,” potentially unseen by other characters until the film’s climax. Fans are already theorizing why Doom and Stark are look-alikes.

Marvel enthusiasts are buzzing with theories about this uncanny resemblance. Some propose that Doom is a variant of Stark from a different multiverse, perhaps an enhanced version of Iron Man. Another popular theory suggests Downey Jr.’s casting as Doom is intentional, with Doom potentially using his magical abilities and scientific prowess to impersonate Stark, gaining the trust of his allies. This would imply he masqueraded as Stark even before Tony’s demise, possibly stepping into the roles of other Marvel heroes.

It’s worth noting that in Marvel Comics, Doom once assumed the identity of Iron Man in the “Infamous Iron Man” series, attempting to reform as a hero after Reed Richards erased his memories. In that storyline, Doom takes up the Iron Man mantle while Stark is in a coma. However, since this occurs post-Secret Wars in the comics, it’s unlikely to directly influence the current film narrative. While the resemblance could simply be coincidental, such an explanation would likely disappoint fans after all the speculation.

Understandably, Marvel fans are speculating about why Victor Von Doom and Tony Stark look alike. Some think Doom is a variant of Stark from another part of the multiverse — he might even be a superior version of Iron Man. Others have a theory as to why Robert Downey Jr. was cast as Doom: They believe that the not-so-good Doc stole Tony’s good looks to pose as him and gain the trust of his friends. As an individual gifted with magical powers who also happens to be a brilliant scientist, Doom can easily create realistic-looking disguises. That might mean that he posed as the superhero for a time before Tony’s death — and could go on to step into the shoes of any Marvel hero out there.

It’s important to note that Doom once took on the mantle of Iron Man in a Marvel Comics series called “Infamous Iron Man.” In it, he tries to become a superhero after Reed Richards gives him a clean mental slate by wiping his memories. Later, Stark ends up in a coma and Doom takes his place in the suit. But since this storyline takes place after the Secret Wars event in the comics, it’s pretty unlikely that it inspired Doom’s new visage. Of course, the simplest reason that Doom and Stark look alike is that it’s just a coincidence, but, after all this speculation, that would definitely be a big let-down for fans.
