Behind the bravado, the fast cars, and the rivalry with Senator Stern, Tony Stark was dying. The palladium core in the arc reactor keeping shrapnel from entering his heart was slowly poisoning his blood. His search for a new element had failed. Facing his own mortality, Tony spiraled into a chaotic lifestyle, handing over the CEO position of Stark Industries to his trusted assistant, Pepper Potts, and appointing his best friend, Rhodey, as the new War Machine pilot.
Back in Malibu, Tony discovered a hidden legacy. Through old film reels left by his father, Howard communicated a message from beyond the grave: the key to a new, sustainable energy source was hidden in the expo’s infrastructure.
