Randy Orton. Crazy? Awesome? Let's see. Kicks his boss in the head to keep him from being fired, okay. RKO's his own girlfriend to prove he's ruthless, yep. Stealing The Undertaker's urn? Been there, done it. Going toe-to-toe with Mick Foley in a hardcore match and winning? He can do it. Trojan Horsing himself into an EXPLODING CAKE in order to sneak attack Triple H?He absolutely went there.
A. J. Lee. How many ways? She pushes people off ladders both to show she is sick of them toying with her affections and to show she's sweet on them. She dresses as Kitana from Mortal Kombat and attempt a fan lift on one of the biggest baddest divas. She sent Kane packing by acting like she had a schoolgirl crush on him and kissing him. Being called crazy is a Berserk Button even if she completely is. These are just some of the things she's done to convince Vince Mcmahon, no bastion of sanity himself, that she is as insane as he is and he appointed her general manager of Raw for her troubles.
Shinsuke Nakamura of course. His quirky mannerisms, taunts and facial expressions have come a long way in establishing him as one of the true standouts of pro wrestling. Needless to say, the guy's really talented and insanely charismatic. YeaOh!
After Matt Hardy became BROKEN he became this. He's the only wrestler who can have a stable that involves a dilapidated boat, a drone and a Mexican gardener. He obsesses over deleting people and calls every enemy "Brother Nero" (including his own brother. His fashion sense looks like he'd fit in with something Tim Burton could've come up with, he has strange "premo-NEE-tions" and can sense the souls of famous historical figures inside zoo animals (like George Washington in a giraffe).
