Boris Bullski was born in Makeyevka, Ukrainian SSR, Soviet Union. According to the Black Widow, he was a KGB-member when he was a young man, and she was his combat instructor for a time. An ambitious official of the Communist Party of the Soviet Union, Boris Bullski was demoted after displeasing his superiors.
While working as an administrator of a Siberian labor camp, he commissioned the imprisoned scientists at the camp to build a suit of armor using the lab of Anton Vanko, the creator of the original Crimson Dynamo armor. Seeking to win back the Party's favor, Bullski conceived the idea of winning a propaganda victory against the West by defeating the American superhero Iron Man. He assigned the scientists to create a powerful suit of titanium armor based on the Iron Man technology, though the inferior resources available to the scientists meant that the armor was twice the size of Iron Man's. Bullski received permission to issue his challenge and Iron Man accepted, defeating Titanium Man in a battle before a worldwide television audience.
Undaunted, Bullski prepared for a rematch by having the suit redesigned and undergoing medical treatments that increased both his size and strength. Traveling to the United States, Bullski fought Iron Man in the skies above Washington, D.C. but was defeated. Withdrawing for retrieval by a Soviet submarine, he discovered that he had been abandoned on orders from Moscow. After working for the Vietnamese Communist scientist Half-Face (who increased his power yet again) for a while, he returned to the service of the Government of the Soviet Union, and was dispatched to the United States to retrieve the third Crimson Dynamo. Finding the Dynamo at Cord Industries, a three-way battle between Titanium Man, Crimson Dynamo, and Iron Man began, during which Titanium Man killed Janice Cord with an electronic beam. Enraged, Iron Man soundly defeated Titanium Man, and left him in the murky depths of the Hudson River.
After the defeat, the two disgraced Soviet agents fled to Communist-controlled Vietnam, where they joined with Radioactive Man to form the Titanic Three. Though Bullski enjoyed working as a sanctioned agent once again, he longed to return to the Soviet Union, and devised a new plan to win his superiors' favor. Adopting the alias of "The Other," he dispatched another former Soviet agent, the Unicorn, to destroy Iron Man. When the Unicorn failed, the Titanium Man went to destroy Iron Man himself, only to fail once more.
Despite his failures, Bullski was in favor with the Soviet government once more, and returned to the United States on a mission for the KGB. By threatening the parents of a Soviet defector named Sergei, he forced the man to design technologically advanced armored suits that could be transformed into small card-like objects. Posing as "the Commander," Bullski used the suits to equip members of the Green Liberation Front (G.L.F.), an organization of disaffected Vietnam War veterans who felt ignored by their country. With the suits, the G.L.F. robbed a New York City bank and the Federal Reserve Bank of New York; though the members believed that they were simply acting as thieves, Bullski used the robberies as a cover for implanting a computer virus that would destroy American financial records, causing chaos in the economy of the United States. Beta Ray Bill and Sif opposed the G.L.F. and the Commander, but when Sergei discovered that his parents were dead he exposed Bullski's true identity and the angry members of the G.L.F. turned on the Titanium Man. Teleporting away, he rematerialized in card form, which Sergei then simply tore and threw away.
Some time later, the new Crimson Dynamo was sent to the United States by the Soviet government to retrieve the remnants for reintegration. The G.L.F. discovered the Crimson Dynamo's mission and attacked him, forcing him to seek assistance by reactivating the Titanium Man, who due to the incomplete nature of his reassembly was still missing body parts. Enraged, Bullski slaughtered the members of the G.L.F., and was only stopped when the Dynamo lured him over the Atlantic Ocean and returned him to card form. Bullski was later restored and continued to serve as Titanium Man, as a member of the Soviet Super-Soldiers and later Remont-4, but felt increasingly despondent as the Soviet Union declined. After an attack on a Stark Enterprises factory in Russia he was believed killed while battling Tony Stark, who was wearing Crimson Dynamo armor that was being controlled by Colonel General Valentin Shatalov, a former friend of Bullski.
Bullski was resurrected by the Ignika and forced to serve Magneto.
