He first appeared in Flash: Iron Heights (2001) and was created by Geoff Johns and Ethan Van Sciver.

Steelworker Tony Woodward caused a riot at a steel plant after he assaulted a female employee.

These scraps somehow turned Tony's body into living metal, which has incredible resistance from harm and grants him superhuman strength.

His body is made from a nearly indestructible steel that provides a high degree of protection from physical and energy attacks.

In "Power Outage", Woodward is released to fight Farooq Gibran / Blackout while Allen was temporarily depowered, only to be killed.

In the episodes "Rupture" and "The Runaway Dinosaur", Team Flash inadvertently turn Woodward into a reanimated corpse, though Allen defeats him once more.
