Piotr Rasputin and his twin brother Alexi were all each other had, since their mother dispised them both. While saving Alexi's life from an oncoming truck, Piotr changed into living metal, stopping the truck from hitting Alexi. He discovered he was a metmutant, but Alexi was not. Alexi's jealousy drove him away leaving Piotr alone. He was later recruited by Niles Cable, a mysterious traveler from the future, to join his team the X-Patrol.
In their first appearance (X-Patrol #1) Ferro Man and his fellow metamutant members were soon involved in the seige of Latkovia against Doctor Doomsday.
