Growing up I was a heel fan in a babyface world so I liked dozens, maybe hundreds, of unpopular wrestlers.
Same. I was a fan of Iron Sheik, Roddy Piper, Ted DiBiase & Rick Rude. Didn't care for Hogan at all. I did like Randy Savage whether he was face or heel. I also liked the Brain Busters. The only faces I was a fan of was Hacksaw Jim Duggan and Tito Santana.
As for current WWE, I'd have to say Eva Marie. I usually trend toward the smark side of things, but man she got SO MUCH HEAT in person and online that I loved it. Add to it that she is very attractive and it was a perfect storm.
