Niko Bellic is the protagonist of Grand Theft Auto IV, a supporting character in The Lost and Damned and The Ballad of Gay Tony, a mentioned character in Grand Theft Auto V, and an easter egg cameo character in Cletus Comics and Sibling Rivalries. He is the main GTA character in Dimitri's Random Wiki Infinity. Niko can also be chosen as the father of your custom protagonist in Grand Theft Auto Online if you have the collector's edition. Niko is Serbian, like his cousin Roman Bellic. Niko met Dimitri Rascalov after killing Vladimir Glebov. They became friends, until Dimitri ordered his best friend to be killed. This led to Dimitri's ultimate betrayal. Niko and Roman had to move to Bohan after Dimitri burned down Niko's apartment and Roman's cab depot. At the end of the game, the player can choose between two endings, Deal or Revenge. In the Revenge ending, Niko kills Dimitri on the ship that brung Niko to Liberty City. In the Deal ending, he kills Dimitri in the final Deal storyline mission. He (Dimitri) is killed on aHappiness Island. In the Deal ending, Niko loses Roman, and in the Revenge ending, it's his girlfriend Kate McReary he loses.
- Niko Bellic has made a cameo appearance in both Cletus Comics and Sibling Rivalries. In CC he appeared in the comic "CleTetchus60", when Cletus (while combined with Tetch 60 as a result of one of Devil-Bot's inventions) was playing GTA IV. In SR he appeared in the comic "Locker 239", when Marco Johnson played GTA IV at school inside of his friend Joel Gonzales's locker.
- In both appearances, Niko was only seen from the back, and he is seen wearing a hat (which may be the one that can be purchased from the Russian Shop in the actual game).
