3 factions who could possibly face The Shield

#2 The Undisputed Era (NXT)

Undisputed Era have dominated NXT

The history between Adam Cole, Kyle O'Reilly, and Bobby Fish is certainly extensive. All three made names for themselves within ROH. Moreover, their paths crossed either as opponents or allies. O'Reilly and Cole would team as Future Shock. Whereas, Fish and O'Reilly teamed as reDragon.

During their time in ROH, all three enjoyed championship success, ranging from the ROH World Championship through to the ROH Tag Team Championship. Ultimately they could be regarded as mainstays within ROH. They certainly helped build the promotion to its current form.

At NXT TakeOver: Brooklyn III, Undisputed Era would debut. It consisted of Cole, O'Reilly, and Fish. Ever since then the group has dominated. Cole became the inaugural NXT North American Champion whereas, Fish and O'Reilly became NXT Tag Team Champions. At NXT TakeOver: New Orleans, Roderick Strong joined the group.

Only time will tell, however, when Undisputed Era debut, it would be excellent for them to feud with The Shield. Both the singles and tag team matches could be epic.
