Ivo Andonov is one of the main antagonists of the popular Bulgarian crime drama series Undercover, appearing as the secondary antagonist of Seasons 1 and 2, the main antagonist of Season 3 and the secondary main antagonist of Season 4. He was a ruthless Bulgarian gangster who initially served as the loyal right-hand man of powerful Bulgarian mafia boss, ex-cop and wealthy businessman Petar Tudzharov, only to betray him later on and take his seat as the new ruling crime lord of the Bulgarian mafia.
He is Dzharo's violent and fearful right-hand man. Ivo was born in a stable and good family of physicians and studied only in elite schools. While still very young, his parents went to work in Israel and Ivo was left in the care of a distant aunt. He eventually grew up on the streets with his parents' money and with the poor interest of his aunt. Soon, he became a criminal and after impressing powerful mafia boss Petar Tudzharov with courage, becomes his right-hand man. Ivo is not a typical criminal. He accepts everything as a military organization. He is a fan of various terrorist factions and thinks of himself as a criminal who fights with the unfair system. He intakes cocaine and likes it very much, although it enhances his aggression. His biggest fear is that he will die at an old age peacefully in his sleep. He dreams of a heroic death, to become a legend. Ivo hates cops and sees them as "selling bastards". He likes the movie "Braveheart", the iconic fictional gangster Sonny Corleone from "The Godfather" (1972) and listens to The Doors.
