As the Avengers find a way to return Iron Man to their reality without bringing Ultron along, they managed to prevent Ghost from stealing Stark Industries technology at the Stark Expo. After swiping the prototype Arc Reactor, the Leader heads to the Wakandan Consulate to steal the Vibranium there with his army of Humanoids. When a guilt-ridden Thor helps Black Panther take down the Leader when the Avengers arrive, the Leader summons his new incarnation of the Cabal (consisting of Arnim Zola, Enchantress, Executioner, and Kang the Conqueror) to fight the Avengers while taking advantage of Iron Man not being there.
When the Avengers trapped by the effects of the Static Expander made from the stolen Stark Industries technology, Black Panther escapes with the stolen Vibranium and avoids Executioner in order to get a team to help him. Upon awakening Vision who helps him fight Executioner and his pet Asgardian dire wolf as well as Enchantress reclaiming the Vibranium for the Leader, Black Panther and Vision must lead Ant-Man, Captain Marvel, Ms. Marvel, and Wasp into finding the Avengers so that they can stop the Cabal.
