Dragan was born in Split, Croatia to an alcoholic father that was never home, and an abusive mother, that took all her anger out on their only child. Dragan wasn't raised particularly well, and got into trouble and fights at the mere age of 5, in his local community. He was admitted late into school, and didn't pay much attention in class, was mean to the teacher, and most other kids that looked weak to him. His way of getting friends was through intimidation, forcing kids to side with him, so they became exempt from getting beaten up.
Throughout his years in school he got into more and more trouble, and eventually got kicked out. When he got kicked out of school, he got kicked out of his home as well, from getting into a fight with his mother and father. Alone on the streets, he had no place to stay, and no place to go. Dragan eventually walked up to a local mechanics shop, where he met with his now father character, Bartolomej or "Bartek" for short. Bartek took Dragan in, gave him a job at the mechanics shop and a place to stay. Dragan eventually moved to his own place, but stuck to his job as a mechanic to stay close to the one person that really cared for him. Though Bartek tought Dragan much, Dragan still suffers from short temper, and easily gets upset if things don't go his way.
BEFORE THE APOCALYPSE:
One day, Bartek had recieved a special order, on a very custom car that a guy from Chernarus wanted done. Bartek assigned Dragan with taking care of the project, as he knew the only thing Dragan really was able to do was work on cars. When Dragan, over the course of about a month or so, was finished, Bartek asked him if he wanted to join him on a road trip to Chernarus to deliver the car. Dragan naturally said yes, since he had never been outside of Croatia, and saw it as some kind of a holiday.
THE BEGINNING OF THE END:
Unfortunately for both of them, they had no idea what they were about to happen in the days that followed. Dragan refuses to talk about it, and has only mentioned that "some fuck-ups" made a bad call during the first hectic days of the apocalypse, leading to the death of Bartek.
Since then, Dragan has made it his mission to survive, and to avenge Bartek, by purging survivors he deem "too stupid to let live". He trusts his own judgement far more than others, which has led to some unfortunate encounters with other survivors in the past. He cares little about others, and mostly about himself, letting very few people get in his way, or tell him what to do. Let's just cross fingers, and hope you don't bump into him.
