Marvel Studios President Kevin Feige has broken his silence on "Dunesday," the comics that have inspired Avengers: Doomsday and Secret Wars, and what led to Robert Downey Jr.'s MCU return as Doctor Doom.

Avengers: Doomsday officially reveals "three distinct universes" that will lead the charge against Doctor Doom. Here's what we know about each.

The official trailer for 'Avengers: Doomsday' confirms that it's heavily based on one comic book storyline that will shatter fans' hearts.

Doomsday trailer has been accompanied by a stunning new poster for the Marvel blockbuster, which seemingly reveals the motivations of Doctor Doom himself.

Recently, Doctor Doom took over the world and turned it into a benign dictatorship, albeit one fuelled by slavery. Part of that saw him kidnap General Ross, the Red Hulk, and use him to gameplay Doom's invasion of the world, imprisoned in Latveria.
