If A Man Be Stone! Tony Stark has returned to his factory for the first time since he came back from Viet Nam to find the place under full alert because somebody had broken in. Taking a group of security guards, they burst in to find that the intruder is S.H.I.E.L.D. agent Jasper Sitwell who has been assigned to protect Stark Industries during Stark and Iron Man's leaves of absence.
Meanwhile, the Grey Gargoyle has escaped from prison, and seeks cover in his civilian guise of Paul Duval. He reads in the paper about Stark Industries development of a cobalt super-weapon, which he hopes to steal in order to use to obtain Thor's Hammer, which the Gargoyle believes will grant him immortality. Resuming his guise as the Gargoyle, he attacks Stark Industries turning any who get in his way into stone. Stark manages to get away from Jasper long enough to change into Iron Man and tries to confront the attacker. Jasper gets in the way and has his weapons turned into stone for his troubles. Iron Man continues to fight the Grey Gargoyle, but eventually the Gargoyle begins slowly changing him to stone. While Jasper tries to call SHIELD for back-up (his radio he finds is broken) the Gargoyle succeeds in turning Iron Man into stone and throws him off the Stark Industries building.. This story is continued next issue...
