Picture this, a spoiled young puppy that was left alone in a cold, Russian winters day without a someone to care for them. Now imagine that as a fellow human being.
You'd think someone who has managed to last this long in Chernarus would have an advantage or characteristics that make them superior to others, but this isn't the case for Anton. Anton would pull the girl's hair in a fight, a skinny yet cheating man who will source out the easiest way to win or avoid conflict using tactics that are frowned upon in combat and war. This was his only way of surviving in such barren of conditions.
To consider Anton to be a functioning human is an overstatement, having relied on heroin and various other drugs to get through the daily grind, he'd have marks across his arms from said use of the drug and a relatively feeble stature, his broad shoulders and reasonably tall make him seem even more brittle although he is yet to get any further injuries during his scavenging.
