Today's Fact
Checked against independent sources — the issues are cited below.
When James Rhodes stepped into the Iron Man armour in Iron Man #170 (1983), he inherited more than a weapons system. The helmet's cybernetics had been tailored to one man's neurology — Tony Stark's — and nobody recalibrated them for the new pilot before Rhodes flew into battle after battle as the armoured Avenger.
The mismatch announced itself as pounding headaches, then curdled into something worse: Rhodes grew erratic, aggressive and convinced that Stark secretly wanted the armour back. The suspicion fed on itself until Rhodes endangered bystanders during a hunt for the villain Vibro, forcing a recovering Stark to cobble together a crude recreation of his earliest grey armour just to stop his best friend.
Recalibrating the helmet did not end the pain, because the headaches had fused with a harder question about whether Rhodes felt worthy of the role at all. Guided by the Shaman, Michael Twoyoungmen, Rhodes confronted that guilt in another dimension around Iron Man #195 (1985), left the armour behind there, and came back clear-headed — a hero on his own terms at last.
Why It's Obscure
The suit fit his body perfectly. It was wired for somebody else's mind, and it billed him for the difference one migraine at a time.
