The Avengers journey into deep space, where they unite the intergalactic races against the Builders - deadly aliens who seek to destroy the known galaxy. While the heroes are gone, Thanos sets his sights on Earth, sending the Black Order to launch the assault. It falls to the other heroes of Earth - the Inhumans, the Black Panther, Namor the Sub-Mariner, Doctor Strange, the X-Men, and more - to defend Attilan, Wakanda, Atlantis, and the rest of the planet. To defeat Thanos, the defending forces will need to deploy a new weapon - one that may be as deadly as the invading force.

Everyone in the galaxy, however, including the ruthless Kree Empire and the stalwart Nova Corps, seems to want that Recorder, who's about as sane as a sandwich with no mustard.

Now, outsiders have returned to plunder Wakanda's riches - including its store of the rare metal. Leading this brutal assault is Klaw, an assassin with the blood of T'Challa's father on his hands.
