Description
Together with the Fantastic Four, the Avengers are in Attilan for the wedding of Quicksilver and Crystal, when suddenly Iron Man and Medusa attack the Alpha Primitives for no reason, then collapse, unconscious. Later that night, the immobile giant Omega comes to life and abducts Crystal. When the Avengers question the Alpha Primitives at Black Bolt's request, Pietro and Mantis are felled as were Iron Man and Medusa, and the Alpha Primitives rise in revolt. Hero after hero falls, as Omega joins the Alphas in their assault. Then the remaining heroes stiffen, falling under another's control, and Omega unmasks to reveal the robotic visage of Ultron.
