Doktori are a Serbian-Bosnian boy band, consisting of Armin Malikic, Uroš Turkulov, Nikola Stanojevic, Marko Balabanovic and Predrag Antic. The band is currently competing in X Factor Adria, a Serbian version of The X Factor franchise.

          In 2013, Armin Malikic, Uroš Turkulov, Nikola Stanojevic, Marko Balabanovic and Predrag Antic auditioned as solo candidates for the first series of the Serbian televised singing competition X Factor Adria. Armin Malikic was a contestant from Bosnia while the other four candidates, Uroš Turkulov, Nikola Stanojevic, Marko Balabanovic and Predrag Antic, came from Serbia. Four of them qualified for bootcamp but failed to progress as solos to the "Boys" category at "Judges' Houses", while Armin did. The place in the band was meant for Aleksa Perovic, but Kristina Kovac, who was asigned to mentor the "Groups" category, was eager to work with Armin and wasn't willing to let him go. The production team decided to make the switch and to form a five-piece boy band in Belgrade, Serbia, in 2013, during the "bootcamp" stage of the competition. Therefore they were qualified for the "Groups" category, which was mentored by Kristina Kovac.  

          For their qualifying song at "Judges' Houses", and their first song as a group, the boy band sang an acoustic version of "She Will Be Loved". Kristina's guest judge Leontina Vukomanovic later commented:

      "Ovo je neki potpuno strani boj bend. Nemam reci,                predobri su."

          Kristina named the boy band Doktori (in reference to Armin's future profession and a comment she made at his audition) and within the first five weeks of the live shows, they were her last act in the competition. Thanks to the public vote, Doktori progressed to the Final 5. The finals will take place in Kombank Arena, Belgrade, 23rd of March, where they will compete for first place with four other finalists.
