Before it was called Avengers: Doomsday, the next Avengers movie was going to be called Avengers: The Kang Dynasty. But changing The Kang Dynasty into Doomsday is not as simple as swapping one character for another and changing a couple of movie logos. Even if we never see Kang onscreen again, we suspect that Kang and Doctor Doom had some history together in the Marvel Cinematic Universe, stuff that may have already happened that we just never saw. That’s the subject of our latest Marvel video; watch it below to learn all the details about these supervillains’ shared history. The next big Marvel multiverse movie, Avengers: Doomsday , is scheduled to open in theaters on December 18, 2026.
