The Birth: Tales of Suspense #69 revealed a new super-villain, a virtual copycat of the Avenger; Iron Man. This was Titanium Man - an enthusiastic member of the Communist party. The man under the armour, Boris Bullski came up with the idea to become Mother Russia's answer to the capitalist hero; Iron Man.

The Legend: After dawning his armour, Bullski decided to gain popularity by thrashing ol' Shell Head. Of course, the Golden Avenger defeated him many times over. But Bullski still never learnt his lesson and Iron Man became his primary foe.
Following initial well-publicized defeats, Bullski submitted to Half Face's biological enhancements. Half-Face was a Chinese scientist who had recued Bullski earlier. While increasing his physical strength and size, it still didn't net him the much-desired victory over Iron Man. Most of Bullski's capabilities really belong to the suit. Nuclear powered, the flight-capable armor fires lasers and greatly increases Bullski's already-inhuman strength.
Along with the Crimson Dynamo and Radioactive Man Titanium Man formed the Titanic Three. But the group was short lived. Later on, under the guise of the Commander, Bullski founded the Green Liberation Front, an organization of disgruntled Viet Nam vets that liked him well enough until they discovered he was a Soviet agent using the group as a front.
Unicorn, another villian was sent into battle with Iron Man by Bullski to test shell head's new armour. But Titanium Man's lackey accidently drowned while trying to return to his master.
