Ironclad's history prior to being recruited as a pilot by Simon Utrecht has yet to be revealed. He was among the small group led by Utrecht to simulate the crash that gave the Fantastic Four their powers, and has remained with the U-Foes ever since.
Alongside his teammates, the U-Foes, he has had encounters with Hulk, Avengers, Spider-Man, Crossfire, Puma, Darkhawk, and Portal.
