We're not big on the popular term "superhero" here at StormWatch, but if there's a finer hero on this planet than Nikolas Kamarov, they're either lying or Jesus.
Born to Kherubim warriors Zealot and John Colt, Nikolas was raised in a foster home in Serbia to protect him from his parent's enemies. As a young boy growing up in cold Siberia, Nikolas Kamarov saw gymnastics as his way out. After great effort and struggle, he achieved the first step toward his dreams: a position on the Soviet Olympic team. After discovering how the rest of the world lived, his regard for the Soviet State turned to deep resentment. But an unsuccessful attempt to defect placed him in the hands of Moscow authorities and at the mercy of an impending judgment.
He was forced to join the Soviet Spetsnaz. After becoming hardened by the horrors of his service, Nikolas was wounded during the ill-fated occupation of Afghanistan. Oddities in his medical records attracted the attention of Stormwatch, the United Nation's superhuman response team, and shortly thereafter the United Nations took the opportunity to activate Kamarov's powers and bring him into Stormwatch.
Heritage
Unbeknownst to Winter he is the son of former Team One members Zealot and John Colt. It wasn't until the oracle Providence told Zealot she would would be reunited with her long lost child. When confronted with Winter after he arrives on a U.N. Stormwatch transport, she sees his hair and hears his Russian accent, and realizes him to be her son, but she doesn't tell him.
Death & Rebirth
Working with Stormwatch for so many years, he was finally promoted to field leader of Stornwatch Prime. When Skywatch becomes overrun with aliens. Winter pilots the orbital platform into the sun to kill the aliens. However his powers allowed him to survive, he became apart of the sun. His experience made him insane and he wanted to destroy the earth. The Authority were then forced to imprison him inside the sun.[1]
Sometime after, The Authority's new Doctor, Habib bin Hassan, informed Jackson King that he can do what his predecessor could not and return Winter to life. He brought Winter's soul into a slightly younger cloned body. Winter's soul was also tethered to his dead teammates; Fahrenheit, Fuji, and Hellstrike. Bringing him back also brought them back. After examining Fahrenheit memories telepathically, she saw a shadowy figure that appears to be a Monitor telling her that the four will be needed.[2] Though, it was later revealed to be a future version of Jackson King who had a hand in resurrecting the four through the use of the Void's powers.[3]
Worlds End
Winter along with his team mates are one of the few operating forces helping the humans left alive after Armageddon.
Kherubim Physiology Physiology: Kherubim resemble humans in appearance, but are physically far stronger and more durable and extremely long-lived, nearly immortal. However an evolutionary drawback to their near-immortality is that Kherans are almost infertile, only very rarely will a Kheran produce offspring. This effect is seen in real world natural environments, as longer living organisms will have fewer offspring than organisms with short lifespans.
Immortality: Like all Kherubim, Winter has virtually an unending lifespan. He will most likely live for centuries or longer. To a non-Kheran, he seems virtually un-aging and unchanging over the centuries.
Superhuman Durability: As a full blooded Kherubim, Winter has a high level of durability. It would take armored piercing bullets to have a serious effect on him as normal bullets, while they would hurt, would not stop him.
Tactical Analysis: Winter has had extensive training in military tactics during his time with the Russian Special Forces.
Hand-to-Hand Combat (Advanced): As a former member of Russian Special Forces, he is highly trained in combat as well as to kill on the first strike.
Gymnastics: Winter is a highly trained Olympic-level gymnast.
Weaknesses
Energy Absorption Limitation: There is a limit to how much energy Winter can absorb, after which point he will begin to take damage. His merging with the sun indicates that Winter might be able to surpass his limits though being part of the sun did cause him great pain and eventual insanity.
