Born in Ukraine, Boris Bullski rose in the ranks of the KGB and eventually was partnered with his fellow comrade Black Widow. When Tony Stark's bodyguard Iron Man was shown to the public, the Soviet Union decided to show their superiority to the United States by creating a powered armor of their own. Made from titanium, a stronger substance than iron, the armor was larger than Iron Man's yet technologically inferior. Bullski used the armor to challenge Iron Man in a one-sided fight, though Stark managed to win.
Titanium Man was created by Stan Lee and Don Heck in 1965 and first appeared in Tales of Suspense # 69.
Major Story Arcs
Versus StarkEarly Titanium Man suit.
The Titanium Man became a recurring enemy of Stark Industries until Boris was 'killed' in Russia by the Crimson Dynamo. Stark was wearing the Crimson Dynamo armor at the time but Boris was killed remotely by the Dynamo's pilot (who could not wear the armor due to injury).
The second Titanium Man power suit was designed by the mutant known as The Gremlin. The Gremlin's carrier as the Titanium Man was short. He first aided the Soviet Super Soldiers (now known as the Winter Guard) in trying to apprehend Magneto for crimes against Russia. The Titanium Man was then targeted by Tony Stark who discovered that his technology was used in a recent upgrade to the Titanium Man & Crimson Dynamo. Stark succeeded in negating the Dynamo's armor but not the Titanium Man's. Titanium Man had Iron Man in a bear hug and Stark tried to use his boot jets to shake his opponent off in the air. Unfortunately the Gremlin was not paying attention and Stark ignited the Titanium Man's armor causing it to explode.
The armor was destroyed and the Gremlin was killed in the explosion. A new Titanium Man has made his presence known to Tony Stark. He attacked Stark during a Space Mission which led to his defeat (he was rescued by a Stark-Fujikawa shuttle) and he later attacked during the hearing to discuss the Superhero Registrations Bill. At some point, Boris Bullski returned from his alleged death and joined forces with The Remont Six, the reincarnation of his previous group The Remont Four.
Ends of the Earth
Doctor Octopus was holding the Earth hostage with his satellites equipped with stealth technology so Spider-Man needed help because the Avengers have been captured by the Sinister Six. Spider-Man sent out an emergency call and several heroes from around the world responded including Titanium Man, Union Jack, Kangaroo, Sabra and the team of Big Hero 6. Spider-Man would provide the heroes with the locations of the missile bases that were launching the satellites into space but warned them that Doctor Octopus has hired a number of mercenaries and assassins to protect his operation. Spider-Man asked the heroes to stop the launch if possible and try to retrieve one of the stealth chips from any satellite. Titanium Man would come into conflict with Scorpion when he attempted to stop the satellite launch in Siberia. The satellite missile would launch during their fight so Titanium Man took flight and grabbed onto the missile but was struck down by a swipe from Scorpion's tail.
