Stops include Latveria (Dr. Doom), the Moon (Black Bolt and the Inhumans), Atlantis (Namor the Sub-Mariner) and the Civil War-ravaged United States, for a meeting with none other than the point man for the U.S. government's implementation of the Superhuman Registration Act: Tony Stark, T'Challa's former Avengers teammate.
