Alex is the daughter of the late exiled Russian oligarch Nikolai Udinov and his wife who were murdered when Alex was a child. Nikolai owned the billion-dollar company Zetrov, which Alex was the sole heir of. She was saved by Nikita as she watched the rest of her family perish. Nikita was powerless to save Alex from anything else as she had to return to Division, and Alex was sold into sex slavery at her very young age by one of her father's former associates.
