Avengers: Doomsday is reportedly omitting several key X-Men characters, with some outlets suggesting this is due to the storyline involving Doctor Doom. The film's production has been described as disorganized, with a large number of roles and a script that was not finished before shooting began. The extent to which X-Men characters will be included in the movie is unclear, with some sources indicating that certain powerful characters will be excluded, while others claim that some of Marvel's most powerful X-Men will make their debut in the film.
