He weighs 78 kg and was diagnosed with acute dissociative disorder, which led him to speak in the third person, referring to himself as "we" or "we're fine," but despite that, he remains a methodical and calculating soldier.

Little is known about Nikto's childhood other than that he was born in Grozny and fled to Moscow with his family as a child during the First Chechen War at the age of 13. During the bout of stabilization, his family returned to Chechnya, but his parents were killed, unleashing unprecedented rage in Nikto, who enlisted in the regular army just in time for the Second Chechen War. There, he participated in most of the operations, witnessed numerous war crimes (both Russian and warlord-sponsored) and began to develop antisocial personality disorder (sociopathy). He also met agent Alexandr "Tachanka" Senaviev during this period. After the Second Chechen War, he enlisted in the Federal Security Service (FSB, a transliteration of the Russian acronym ФСБ), where he served as a field agent until joining the FSB's Spetsnaz. He was awarded Russia's highest military award, and served as an undercover agent in Chechnya... until he was caught. He was tortured by a certain "Mr. Z" (we believe this to be the warlord Inram Zhakaev), leaving his face disfigured, now completely sociopathic, and forcing him to wear a mask. The FSB succeeded him after (insistently) wanting to make him a special operations asset in Chechnya again.

Psychological profile

Nikto exhibits all the traits of a sociopath, but he doesn't seem to enjoy killing, or so his colleagues Shuhrat "Fuze" Kessikbayev and Maxim "Kapkan" Basuda say. In my experience, Nikto is controllable; he's a cool-headed, methodical, calculating soldier with nerves and skills of steel. I think his only weakness is being a bit more communicative (he almost failed two missions due to his poor communication skills), but otherwise, he could be an excellent operator.
