Mark III

Tony's Mark III (3) was used against Obadiah Stane in his "Iron Monger" armor. In an app, quote, "I almost failed toreach Pepper in time when she was attacked by Stane in his "Iron Monger" armor." In Iron Man, it swiftly replaced the Mark II. It was followed by the ''Mark IV (4). This set the road for the newer suits of the Iron Man franchise''.
