The manhunt is on! As director of S.H.I.E.L.D., Tony Stark had sole possession of a database that contained the secret identities of every registered hero in the country. But now, S.H.I.E.L.D. is no more. A casualty in the aftermath of the Skrull's Secret Invasion, the international peacekeeping organization has been replaced by the Dark Reign of Norman Osborn and his newly conceived H.A.M.M.E.R. - a less kind, decidedly less gentle remaking of the legendary security force founded by Nick Fury. Osborn now has all the power he ever wanted minus the most important ingredient, the registration database, which is stored in the only place Stark could guarantee its safe keeping - inside his Extremis-enhanced brain. With Tony Stark in disgrace and on the run, the orders have come down from the highest level to every mercenary, mobster and Osborn minion: 'Bring me the head of Tony Stark!'
