Generally speaking, Grand Theft Auto IV was not heavy on comedy. There were some elements of the traditional humour Rockstar usually favour, but the game was much more of a serious affair when analysed at large. Due to this fact, characters like Brucie Kibbutz only stood out even more. The guy was ludicrously over-the-top, but all the more entertaining for it. Intriguingly, there was a sense of danger surrounding Brucie. He was clearly mentally ill, something the protagonist of IV, Niko Bellic picks up on fairly early on. By quite a long way, Kibbutz is the most ridiculous character in the fourth main entry to the series. Many playing the game likely thought for sure that he'd end up dead by the end of the main quest. That didn't happen, which leaves the chance for an appearance in GTA VI open. There's no shortage of creativity at Rockstar when it comes to creating overblown characters, but it'd be a waste for Brucie not to make another showing. Playing devil's advocate, he'd even be ideal as a main protagonist, because he's absolutely insane. That's what GTA is all about!
