Dom from gears of war comes close (seriously shut up about your wife!) but Rico from Killzone is probably the most unlikable gobshite to ever grace a video game... I would say more about him but I would probably get banned from the site (and deservedly so) for using language so offensive that people vomit on their keyboards... I hate him sooooooooooooo much, not one single person can make argument for this tool, in fact he is such an asshole that from now on I will refer to any character who annoys me as "a bit of a Rico."
