Just when it seemed like NXT TakeOver: Vengeance Day would go off the air without any major surprises, Adam Cole truly "shocked the system". He superkicked Finn Balor during their show-closing pose, much to the bewilderment of Kyle O'Reilly.

Cole then superkicked his long-time friend, ending the Undisputed Era as we know it. While it was speculated for a while, nobody truly believed that NXT's biggest faction would break up before moving to RAW or SmackDown. These are exciting times following NXT TakeOver: Vengeance Day, but there is a potential downside.

Unless a new faction is formed from the rubble, it would be difficult to see Cole, O'Reilly, and Strong succeed on WWE's main roster. The Undisputed Era had a great chance of success as a unit, but their fate remains to be seen. The good thing, though, is that neither of them will be leaving NXT for a while.

Adam Cole's heel turn at NXT TakeOver: Vengeance Day opens up a ton of storytelling possibilities. Finn Balor will likely defend the NXT Championship against him, possibly with Kyle O'Reilly in the mix as well. A triple threat between them could happen at WrestleMania 37 since it is a two-night event.

However, the money match is between Cole and O'Reilly. With Roderick Strong caught in the middle, there is a lot of uncertainty and intrigue surrounding the split. One thing can be guaranteed, though. Their eventual singles match at the next NXT TakeOver will be a classic.

What do you think will happen next? Are you happy with Adam Cole turning heel and Undisputed Era splitting up?
