Nikto is a 5'8", 36-year-old blue-eyed Russian with a disfigured face that he hides with a mask he never takes off, with black hair, and a thick Russian accent, he's rather quiet, very attentive and cold, but also gentle, commanding and dominant, or just cold and stoic. He has DID, and two alters, one who's a happy personality, and one who's serious.

Zakhaev was the one that disfigured his face when he captured him. He's a berserker, and can transform into a vicious brown bear when enraged.
