After Vibro escapes from jail, he seeks vengeance against his former employer Fortney & Iron Man, & he threatens to level a town unless they come to him. In their initial encounter, Vibro's power causes Iron Man to lose control of his armor. Morley theorizes that Vibro's power is somehow connected to the fault. Iron Man draws Vibro away from the fault so that his power is weakened. Iron Man takes Vibro into custody after threatening to drop him from a height in the jeep he was using to pursue Iron Man.
