Vanye Teskerovic was a member of a Serbian death squad responsible for numerous acts of ethnic cleansing. When the government fell, she used her skills as a mercenary for hire. During one of these missions, where she was asked to steal an experimental serum from a Russian lab used for the creation of super soldiers, her and her team were ambushed, and through a violent series of events, her team was killed. While trying to make her escape, a beaker of acid exploded in her face, scarring it, and burning her eyes from their sockets. Realizing that her only chance for survival was to take the serum, she took it. The serum gave her inhuman speed, enhanced her toughness, and gave her a sort of radar sense to compensate for the loss of her eyes, as well as the ability to draw upon nether energies to fight and heal herself a little bit. It also burned out every pain receptor in her body, so that now she is incapable of feeling any pain.
She escaped and found the people responsible for the doublecross. She wears their skulls as ornaments on her costume. Fleeing to the Rogue Isles, she has banded with a small group of people who have offered a sort of sanctuary, as well as allowing her the freedom to pursue her various forms of sadistic behaviour.
Currently she is wanted by Interpol, the FBI, CIA, Chechens, the Russians, the UN for her various war crimes and crimes against humanity, and is also being pursued by various other law enforcement agencies for purported terrorist acts, not the least of which was the release of a deadly nerve gas that ate away the victim's skin in an Eastern European elementary school.
She is considered extremely violent, sadistic, and has no qualms about commiting murder, torture, assassination, terrorism, espionage, and brutality.
Has been found guilty in absentia in Bosnia, Croatia, Russia, Albania, and is marked to be executed on sight.
Currently employed as an enforcer/bodyguard for a new villain group. Considered unemplyable outside of the Rogue Isles due to unpredictable nature and extremely violent tendencies.
