10 Most Powerful Characters Killed By Wolverine
5. Omega Red
Russian serial killer Arkady Gregorivich Rossovich was captured and enrolled in a 1960s KGB project to create a Russian supersoldier who could stand against Captain America.
Already a mutant with enhanced speed, strength, and durability as well as the ability to produce pheromones that poisoned those too close to him, the experiments left Arkady with carbonadium (a weaker, but more malleable, form of adamantium) tentacles implanted into his arms - and a big problem. The carbonadium was slowly poisoning him and he had to use the tentacles to drain the life force of others simply to keep his nervous system working.
The carbonadium synthesizer, a device that could stabilize this condition, was stolen by the CIA's mutant covert ops group, Team X, in the first meeting between Arkady and Wolverine. Years later, after being put into suspended animation when the Soviets lost all trust for him, Omega Red was woken and immediately began hunting the members of Team X in search of the device that could cure him of his only weakness.
In a final encounter that Red has since miraculously recovered from, Wolverine drove the Muramasa blade through Arkady's heart.
