Next to nothing is known about Siberion except he is extremely deadly and an obedient soldier. When the Peristrike Force
traveled to America to abduct their creator, Dr. Anatoly Vonya, Siberion was on hand to stop anyone in their way – including local law enforcement. He wasn't prepared to tackle a hero with powers to rival his own, but when Darkhawk
showed up Siberion met his match and was beaten twice; the second was just before the Peristrike Force was about to flee back to Russia. Darkhawk tried to ambush the terrorists in his civilian identity, but their leader, Psi-Wolf
, saw through his charade. Psi-Wolf ordered Siberion to freeze Darkhawk, but he inadvertently froze Vonya when the doctor came to the boy's rescue. Siberion was rendered unconscious soon after, but the damage had already been done with Vonya's death. Siberion was left for the police.
