Bron Breakker defends his NXT Championship against Grayson Waller in what has quickly evolved into a high-stakes, tension-filled rivalry.

Since winning the first-ever Men’s Iron Survivor Challenge at NXT Deadline, Grayson Waller has made his disdain for Breakker known, using any chance he gets to belittle and embarrass the champion, highlighted by wearing a hidden armored vest and baiting the champion into Spearing him.

Breakker has grown increasingly frustrated by the antics of the challenger, smashing equipment backstage and eventually attacking Waller on the latest episode of "The Grayson Waller Effect." 

Will Breakker stave off another dangerous challenge, or will the Waller era begin in NXT? Tune in to New Year's Evil on Tuesday at 8/7 C on USA to find out!
