Niko's nationality is never specified in the game, and has been a subject of some debate.
After becoming involved with a Russian crime syndicate and discovering that his unit was sold out to enemy forces, he decides to move to Liberty City to pursue the American Dream, inspired by the tales of luxury and riches of his cousin Roman, who had been living there for the last decade. Niko is a war veteran from Eastern Europe, where he witnessed some of the worst atrocities humans are capable of, causing him to develop a very cynical view on life. Michael Hollick provided the character's voice and motion capture. He also makes non-playable appearances in the game's episodic content The Lost and Damned and The Ballad of Gay Tony, both released in 2009.
Niko Bellic is a fictional character and the playable protagonist of Rockstar North's 2008 video game Grand Theft Auto IV, the sixth main installment in Rockstar Games' Grand Theft Auto series.
