Doctor Doom faces multiverse heroes in 'Avengers: Doomsday' promo

Marvel Studios showed fans a brand-new look at a big movie called 'Avengers: Doomsday' at a special Disney fan event called D23.

The movie features many superheroes who must face a very powerful villain named Doctor Doom.

In this movie, Robert Downey Jr., who used to play Iron Man, now plays Doctor Doom.

Some heroes from older Marvel movies are coming back, including Steve Rogers and Peggy Carter.

A fun part of the show was when Hugh Jackman and Ryan Reynolds sent a funny video asking if they could join the movie too.

The movie's directors are Anthony and Joe Russo, who have directed other big Avengers movies.

The story follows heroes from three different universes who are heading toward a big collision.

Marvel also shared a new poster for the film at the event.

Everyone is excited to see what happens when these heroes meet Doctor Doom.
