Kondrati Topolov (Russian: Кондрат Юрьевич Топалов) also known as Gremlin, was the son of the Gargoyle, a deformed, mutant genius who worked for the Soviet government until he captured the Hulk for study. After the encounter, the Hulk cured the Gargoyle, who later commited suicide - never knowing that he had an incoming child. The young Gremlin was tricked to believe that the Hulk had killed his father and, wanting revenge, the Gremlin worked for the Soviet government as a child genius, first fighting the Hulk in Canada. Albeit the Hulk escaped, the Gremlin captured and retained General Ross.
He was presumed killed when fighting Iron Man during the first Armor Wars when his titanium armor had caught fire and he plunged into a frozen-over lake.
During the second Armor Wars, Tony briefly battled what he believed to be the Gremlin's ghost (in the form of his Titanium Man armor). The Titanium Man taunts him and vows revenge against him. Iron Man confesses to being responsible for Gremlin’s death. But at that moment, the truth behind the farce is revealed. It is not the ghost of the Gremlin/Titanium Man that Tony is facing, but rather it is the Living Laser.
Superhuman genius, about equal to Tony Stark. His Titanium Man armor had superhuman strength, flight, internal energy weapons, life-support and was durable enough to withstand hits from light anti-tank weapons.
