6. Kane
WWE.comThe Big Red Monster is the man that caused The Shield to turn heel. He is the man that then set out to make them pay for betraying The Authority. And in both cases, he ended up flat on his back. Kane does not often get the opportunity to face a WWE Superstar that is on his level physically. But despite being seven inches taller and outweighing him by nearly 60 lbs, Kane has found an opponent in Roman Reigns that will take him to his limit. And there is definitely a great back-story for this feud. What more do two guys need to go to war and entertain fans at the same time? The fact is that Roman has heat with Triple H and that rivalry is coming soon. But there is likely no way that The Game will just allow that match to happen without trying to throw some roadblocks in Roman's path first. Kane would be a massive roadblock and working him would would keep Roman in direct contact with The Authority. Hunter could use The Devil's Favorite Demon to deal with his biggest problem in Roman Reigns. Triple H would surely do anything it took to stop Roman and that means Kane would be the man to step up to the plate. But he would have to go down just as quickly. Beating Kane would go a long way to exorcising the ghosts of Seth Rollins' betrayal. Getting a win over The Authority's enforcer would be the first step on Roman's road to Triple H.
