Is this the end of the most dominant faction in NXT history?

The Undisputed ERA seemingly imploded at NXT TakeOver: Vengeance Day, with Adam Cole shocking the NXT Universe by betraying longtime friend Kyle O’Reilly.

Cole, O’Reilly and Roderick Strong arrived as reinforcements for NXT Champion Finn Bálor, who was ambushed by Oney Lorcan & Danny Burch after retaining his title against Pete Dunne.

The tenuous alliance formed between The UE and Bálor in recent months initially appeared stronger than ever — and then Cole blasted Bálor with a superkick, bewildering his UE allies.

Cole still had one more shocker up his sleeve, though. Moments later, the former NXT Champion uncorked another superkick, this time to O’Reilly, stunning the Capitol Wrestling Center.

Cole’s treachery elicited reactions from around the NXT Universe.

What possessed Cole to do this, and how will O’Reilly and Bálor respond?
