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.

Powers
Ironclad's body is covered in a mettallic-like and remarkably tough armored hide, able to resist most forms of attack. In addition, he is monstrously strong (going toe-to-toe with the Hulk) can increase his density to unknown limits, gaining additional resistence to attacks.
