16. Brucie

First appeared in: Grand Theft Auto IV (2008)

You'll be hard pressed to find another character within Liberty City as overzealous and straight-up bonkers as Brucie Kibbutz. A fitness fanatic who's constantly juiced-up, he's a side-plot to the GTA IV story but a loyal ally to the game's protagonist, Niko Bellic and, arguably, the best thing in the entire game.

Dealing out 'roid-fuelled revenge missions and car-boosting assignments, Brucie's unique personality eclipses almost everyone else in Rockstar's open world opus. Whether he's espousing his theories on being 'genetically different', imploring Niko to 'Stay alpha' or layering on the false machismo to distract from his dubious sexuality (the Asian tattoo on his arm reads 'shemale'), Brucie and his associated missions are a masterstroke of comedy characterisation.

Rockstar knew they were onto a good thing with Brucie, too, having him return in The Ballard of Gay Tony expansion and introducing his brother to delve further into the 'roid monkey's lunatic back story. Brucie is constantly asserting his position as number one in Liberty City and, in an odd way, it's hard to argue.
