#2 The Fiend
Seth Rollins is set to defend his Universal Championship for the first time in his second reign against The Monster Among Men Braun Strowman. Over the past few weeks, things have really heated up between the RAW Tag Team Champions.
It's obvious that Rollins won't be dropping the Universal Championship anytime soon. WWE has built him up as 'The Beast Slayer' throughout the entire year and won't book him to lose so easily, and in his first title defense since winning the belt at SummerSlam.
Since Strowman's chances of capturing the Universal title are very low and WWE wouldn't damage his credibility by booking him to lose clean, the match might end in a way that leaves both competitors as credible in the end.
In addition, the arena where Hell In A Cell is taking place is advertising 'The Fiend' Bray Wyatt to either face Seth Rollins or Braun Strowman at the event, so there's a huge possibility that he attacks one of the two wrestlers at Clash Of Champions.
The Fiend interrupting the match will be the perfect finish as it will protect Strowman's credibility and also set up a huge title match against Rollins or Strowman at the next PPV.
