The next Avengers movie, Avengers: Doomsday, is set to bring a brand new big bad to the fore in the MCU: Doctor Doom, played by Robert Downey Jr. But just how much introduction does a new Thanos-level villain need? Marvel fans are discussing what they think is the appropriate level of setup.

Polygon got a chance to talk with North in the lead-up to his first stint as lead writer of a big Marvel crossover event, One World Under Doom — a nine-issue story in which Doctor Doom has already taken over the world on the first page, and it’s up to the Avengers and the Fantastic Four to figure out how he did it, and how to undo it.

Benedict Cumberbatch has said his Marvel Cinematic Universe character Doctor Strange is skipping the next big team up in Avengers Doomsday but will play a "central role" in its sequel Avengers Secret Wars.
