Now we know: Doctor Doom is coming to the Marvel Cinematic Universe. Robert Downey Jr.’s Doom will be the focal point of Avengers: Doomsday and Avengers: Secret Wars. What we don’t know is how exactly Doom will take over the multiverse.

That, of course, is adamantium. In our latest Marvel video, we’ll explain what the introduction of adamantium means to the MCU, and how a very cool Doctor Doom storyline from Marvel Comics could easily be adapted to Doomsday and Secret Wars. We’ll also explore how this storyline will likely be set up in Captain America: Brave New World and Thunderbolts. Watch our full breakdown of this theory below:
