The Quantum Drive is a high-capacity data storage device that contained a comprehensive list of effective counter-meassures against every major super hero on the planet (dubbed "Axiom Protocols"). It was stolen from the Pentagon by an individual using a counterfeit Iron Man Armor and subsequently put up for auction. John Walker purchased it for the Pentagon, but was knocked out by Phil Coulson who threw the suitcase with the drive in it into the ocean. A S.H.I.E.L.D. team retrieved it soon afterwards.
