Iron Man #191 1985

In Iron Man #191, Jim Rhodes's mental state deteriorates, leading to increasingly erratic behavior in the Iron Man armor. As the villain Vibro escapes and seeks revenge, Tony Stark grapples with his reluctance to don the armor again. This issue is notable as it depicts the critical moment where Tony, witnessing Rhodey's destructive actions and the escalating threat, begrudgingly decides to step back into the Iron Man suit himself. It's a pivotal chapter in the ongoing narrative of who truly is Iron Man.
