During the Armor Wars, Iron Man found himself facing the government-sanctioned armored assassin Firepower. Against this walking, flying armored arsenal, even the Silver Centurion armor did not stand a chance, and it was destroyed. Reluctant to enter the fray again, but forced into action, Stark designed a new suit, even more powerful and versatile than its predecessor, designed specifically to negate Firepower's original advantages, such as a means of disrupting Firepower's targeting systems, a gauntlet-generated energy shield, and more powerful boosters for increased speed. It made short work of Firepower, and Stark was so horrified of the destructive potential of the armor should it fall into the wrong hands, he resolved to destroy it. After the confrontation with Firepower, he changed his mind, encoding all subsequent armors with a series of complex microchips that would self-destruct if duplication was attempted by anyone else without specific passcodes known only to Stark. This armor resembled the classic armor which had endured for many years, with some minor cosmetic changes. Its appearance changed somewhat, mainly becoming more bulky, ostensibly to increase thruster power (its massive boot-jets earning it the some-time nickname "coffeepot armor"). It was also the first armor to incorporate a beta-particle generator, radically reducing Iron Man's external power needs and boosting his offensive power.
