The fourth Red Guardian, Josef Petkus, was a special operative for the intelligence agencies of the Soviet Union, and appeared as a member of the militant Supreme Soviets. Alongside the Supreme Soviets, he attacked the Soviet Super-Soldiers for defecting from the Soviet Union. Alongside Captain America, he later battled a bear-like creature composed of the Darkforce.
The Supreme Soviets later became known as the People's Protectorate after the fall of the Soviet Union.
Alongside the People's Protectorate, he teamed with the Avengers and Alpha Flight to battle the Peace Corpse, the Atlantean Army, and the Combine. They also battled the Hulk over a former Russian spy partly responsible for Banner's transformation.
The People's Protectorate eventually merged with the mutant vigilante unit called Siberforce, becoming the Winter Guard. Petkus was the overall leader of this unit, now calling himself the Steel Guardian.
After the death of Darkstar, her brother Vanguard convinced Steel Guardian and most of their teammates to leave Russian service. Thye entered something known as the anomaly, which was really a portal to Limbo and where forced to serve under Immortus. While fighting off Dire Wraiths in Limbo, they discovered that Fantasia was actually a Dire Wraith all along. Steel Guardian was impaled in a battle against her forces.
