Moon Knight eventually upgrades his armor to adamantium armor rather than his original Kevlar costume. This upgrade is critical since Moon Knight needs the armor to hold his body together after being infected by the then-possessed Hobgoblin. The disease is revealed to be the villain known as Demogoblin trying to possess him. With the help of Doctor Strange and Mister Fantastic, the Demogoblin parasite is removed. Moon Knight seemingly severs his ties to the Avengers by burning his membership ID card after being brought in by Thor to answer charges in regard to his illegal actions against Doctor Doom. By the end of the series, Moon Knight is killed violently, sacrificing himself to save his loved ones from a computerized villain called Seth and his "Zero Hour" program.
