AKA: Arkady Gregorivich
A Russian mutant, Arkady was part of a program planned by the KGB to turn him into a super-soldier. Unfortunately for them (and him), the procedure was interrupted by the Weapon X team, including Wolverine, who stole a crucial piece of machinery.
After some time in cold storage limbo, Omega was freed by the Hand, who sent him after Logan and co with a thirst for revenge. With Carbonadim armour, super strength and body pheromones deadly to anyone nearby (what – super BO?) he’s been a thorn in Wolverine’s side for years.
