A brand new trailer for Avengers: Doomsday premiered at CinemaCon... introduced by none other than Robert Downey Jr.
In the two-minute trailer, we once again see the ruins of the X-Mansion. Professor Xavier watches in horror as flames appear in the sky. We hear who we think is Doctor Doom say, "Something's coming, something we may not be able to deter..." The trailer cuts to the New Avengers tower, in which the Fantastic Four are introduced to Bucky, Ant-Man, and Captain America. Thor tells the group that they must stand together, or everything they sacrificed "will be for nothing."
