Omega Red

Arkady Rossovich is a Russian mutant formerly employed by the country formerly known as the Soviet Union. He was captured by the Interpol agent Banshee and turned over to the KGB, who wanted to create a super soldier similar to Captain America. Omega Red was the end result. After repeatedly tangling with Wolverine and Sabretooth in their days as Cold War spies, Omega Red was put in cryo suspension, until a method could be found to control him. Unfortunately, The Hand reawakened him shortly after the fall of the Soviet Union.

Omega Red has a retractable, prehensile tentacle made of Carbonadium -- A flexible alloy nearly as strong as Adamantium -- in each of his arms. Combined with his "Death Factor" mutant ability, wherein he emits toxic pheromones, and his need to absorb the life force of other beings until he can claim the Carbonadium Synthesizer, a device that would 'purify' the Carbonadium in his system, Omega Red is as deadly as they come.
