Ivo Andonov is a fictional character and one of the main protagonists of the BNT crime series Undercover (Bulgarian: Pod Prikritie).
Andonov is portrayed by Zahari Baharov as an unmerciful and ruthless gangster, who initially served as the loyal right-hand man of a powerful ex-cop, wealthy businessman and Bulgarian mafia boss, Peter Tudzharov (Dzharo).
Andonov eventually takes the seat of his boss as the new ruling crime lord of the Bulgarian mafia after Tudzharov's incarceration and death.
When he was very young, his parents relocated to Israel for work and Ivo was left in the care of a distant aunt.
As Dzharo's violent and feared right-hand man, Ivo is not a typical criminal, viewing everything as a military organization.

Vasileva notifies Tudzharov that Sunny is alive, and Dzharo orders Andonov killed.
As he returns to his home after the conversation with Hristov, Ivo sees that the police had arrested Dzharo.
In Season 3, after Tudzharov is arrested and sentenced, Ivo reunites his crew; The Hook, Adriana, and Zdravko Kiselov, also known as The Hair, and starts his own criminal group.
