Chris Jericho for very, very obvious reasons. Followed by Brock Lesnar, every time he appears it receives that "shit's about to go down" reaction, which I can't say for anyone else. The guy's essentially a walking mark out moment. And then he's followed by Dean Ambrose, his portion of the promo last Raw reinvigorated my love for The Shield that was lost admittedly due to my lack of paying attention, and the also decision to brand them together with Heyman.
Yes, I'm aware Punk isn't in the top three despite being listed as my favorite. I'm too lazy to change it, especially since two of three topping him are only going to be there for a short amount of time.
