3. Stephanie McMahon
Vince McMahon's daughter has made quite an impact over the years, and not just in terms of the business side of professional wrestling. A former Women's Champion, Stephanie is a tough girl who has plenty of in ring experience along with some boxing lessons under her belt. Being married to Triple H doesn't hurt either. Needless to say, she's far more experience in fighting and wrestler than she used to be when she first started showing up on WWE television. She has also shown herself to have a big of an ego, especially when she has the power to control the destinies of other wrestlers. But how would she react towards a woman who doesn't fall under her professional wrestling radar? The WWE Universe has witnessed many moments where an authority figure decides to step back into the squared circle, so it's not impossible to imagine Stephanie lacing up the boots once more if Rousey comes knocking at her door. Rousey being rowdy would certainly not be "best for business" in the eyes of Stephanie, and if things got too personal, nobody's going to able to stop these two from butting heads in the ring. Rousey could fit the bill for representing anti-authority, and if Rousey is not willing to give Stephanie respect, then the boss's daughter is going to punish her though any means necessary; that includes throwing her into the ring. One could imagine a situation where Stephanie would throw obstacle after obstacle in front of Rousey in order to hold her back and keep her from throwing a single punch at her direction. If Rousey accepts the challenge, it's going to be a tough hill to climb. she better remember that it's not safe to ever cross the boss. Especially if that boss happens to have the name McMahon.
