NIKO BELLICVoiced by Michael Hollick.
"Life is complicated. I killed people. Smuggled people. Sold people. Perhaps here, things will be different."
Grand Theft Auto IV's protagonist, Niko Bellic, is an ex-soldier from Eastern Europe who moved to Liberty City to escape his past and pursue the "American Dream." Niko was persuaded to move by his cousin Roman, who claimed to be living there with beautiful women, sports cars and lots of money. It soon becomes apparent, however, that Roman lied in order to cover up his own failures in life - the truth is he runs a failing taxi business, has mounting debts, and various criminals from Liberty City's underworld have put a price on his head. Niko also has other motivations for moving to Liberty City, which are revealed as the story unfolds.
