Number 5: Chris Jericho
Possibly the smartest heel of them all, Chris Jericho came back from a 30 day suspension and the crowd loved him like they always do. It look him only a few words for the crowd to begin to boo him. He plays with the crowd everytime he comes back, face or heel. His personality shines through more as a face, but his intelligence and manipulative ways are unmatched as a heel. He is not the brash, loud, or varsity cockiness, he has his own swagger to it. He can speak soft and slow, gain more heat that way, and then execute his arsenal in the ring. HBK, John Cena, Edge, whoever he faces he immediately can adapt from face to heel in a second. That is the beauty of Chris Jericho. Applaud his intelligence to make that switch and make it effective each time.
