Wow. There's so many. As a wrestling fan growing up I can name a few. Ric Flair during the late 70's and 80's, for sure. That 'I'm rich, styling and profiling' attitude pissed a lot of people off. He was the best at drawing heat, no question.
Abdullah the Butcher, Terry Funk, Harley Race. There were tons of heel wrestlers who were great at it. Nowadays, who cares. Wrestling is absolutely terrible these days. No good heel or face characters that anyone still cares about.
Karl Kox probably has a few he can rattle of.
