Iron Man had battled the criminal called Force, and had recruited and helped him. Tony Stark was examining Forces' armor and realized a lot of the technology resembled that of Iron Man's armor technology. It was then revealed that Spymaster had stolen some Iron Man armor secrets and had sold them to Justin Hammer, who then sold them to criminals and heroes alike. Tony Stark then invented "Negator Packs" that could destroy his technology on contact.
