Doomsday trailer revealing Cyclops' suit, a look back at all of Scott Summers' movie costumes reveals his clear best suit.

The X-Men will return in Avengers: Doomsday, promises the latest (and perhaps best) teaser for Marvel 's next big Avengers event. The third teaser trailer for Avengers: Doomsday focuses on the X-Men, promising the return of Patrick Stewart as Professor X, Ian McKellen as Magneto, and James Marsden as Cyclops.

James Marsden's Cyclops screams and uses his powers in the X-Men teaser for Avengers: Doomsday, hinting at a major tragedy.

Marvel has officially released the X-Men teaser trailer for Avengers: Doomsday, after a week spent in theaters ahead of Avatar: Fire and Ash.

While it is nice to see these stalwarts return as their respective Marvel characters, the mic-drop moment in this new Avengers: Doomsday teaser doesn't belong to them. Instead, the best moment belongs to none other than Cyclops, played by James Marsden, the same actor who played the leader of the X-Men in the original film franchise.

Doomsday trailer indicates that the superhero spectacular might put its own spin on the Days of Future Past storyline.
