Can't name one on top of my head but I think the worse trainers are those who just pump up a fighter in the corner without saying a single word of advise "Yeah champ! Uungh! Ya' know what I am saying?! Hell yeah! Unghh! Go get him boy!" acting like a gangsta' rapper. If I was winning I would still want to hear what I have to keep doing to get a victory and not just a guy pumping me up.
