Chris Jericho
Y2J has everything needed to become one of the biggest heels in the pro-wrestling business. Much like a modern version of Ric Flair, Jericho is the type of character that fans simply love to boo. And, if done right, his ability to come off as "cool" and "hip" could make him a popular bad guy in the mold of Kevin Nash, Scott Hall, Triple H, etc.
Jericho has paid his dues over the years and WWE has shown that they are willing to push him (by making him the first ever WWE Undisputed Champion). Jericho is also still very young, is able to deliver very entertaining promos, and can put on top notch wrestling matches when needed. While Jericho has yet to establish the powerful friends needed to speed up his climb to the top, there is little doubt that he will eventually get there and establish him as a top caliber talent.
Chris Jericho has the look, the natural charisma, and the wrestling ability. He has also shown that he can avoid serious injury which will prove to be extremely important in the long run.
While he may never become one of the top 2-3 wrestlers in the game, he is the type of guy who will end up solidifying himself as one of wrestling’s top talents for years to come. Afterall, he IS the King of the World.
