Did David Harbour Just Drop a Massive Avengers: Doomsday Spoiler?

Stranger Things and Marvel actor David Harbour has apparently confirmed a major plot twist from Avengers: Doomsday, according to Variety. When asked to recite a line without context, Harbour delivered a quote using his Russian accent as his Red Guardian character. The dialogue confirms that Doctor Doom's appearance as Tony Stark will occur in the film, and Harbour's character will be present for the reveal.

This is a surprising confirmation, as fans have been speculating about the timing of this twist, with some suggesting it would be saved for Avengers: Secret Wars. The revelation will likely shock former allies of Tony Stark, such as Chris Evans' Steve Rogers and Chris Hemsworth's Thor. Marvel seems to be confirming that Doctor Doom comes from the Fantastic Four's reality, a different branch of the multiverse than the main 616 timeline.

Therefore, two versions of the same character could exist. The exact origins of Doctor Doom remain unclear, but fans have some theories. Harbour has been navigating personal issues, including his relationship with singer Lily Allen and co-star Millie Bobby Brown, alongside his work on projects like Stranger Things and the upcoming John Rambo.
