Sergei

Sergei is a member of the Faustin Family and appears in Grand Theft Auto IV. He was Mikhail Faustin's bodyguard.

It's impossible that Sergei is the assassin hired by Dimitri Rascalov that appears in Mr. and Mrs. Bellic (Deal) despite they shares the same NPC because Sergei is voiced by Jeff Norris and the killer was voiced by Jacek Krawczyk.

Mission Appearances

 * GTA IV
 * No Love Lost

Trivia

 * If the player would have failed the random encounter with Mel the first time, the second time, when talking to Niko, he'll mention that one of his reasons to stop drinking was "not hanging around with losers like Sergei". Given the fact that Rockstar tries to avoid giving the same name to two characters in the same game, Mel could be talking about Sergei.
 * Sergei bares a large resemblance to Agent 47 from the Hitman series, with the same suit and both of them are bald.
