5 Factions that could challenge The Shield

#1 The Undisputed Era

The Undisputed Era would live up to their name with a win over The Shield

This dream match won't be happening anytime soon, as there is a time limit set on the current Shield reunion, and the Undisputed Era are clearly going to be running NXT for quite some time. Adam Cole, Bobby Fish, and Kyle O'Reilly would be the best possible trio to challenge Dean Ambrose, Seth Rollins, and Roman Reigns.

The Undisputed Era has shocked the system in NXT, leaving a trail of bodies everywhere they go. They have assaulted security guards, competitors, gotten involved in singles matches, UK matches, and even women's matches. Literally, nobody is safe from Cole, Fish, and O'Reilly.

If the Undisputed Era try to come up in the main roster in the future and pull the same stunts, then the hounds of justice will surely come together once more to put an end to it. Much like the Shield, the Undisputed Era has no weak links, no cracks in the armour, and they operate well as a unit. If you take any one member from the Shield and pit him against any one member of the Undisputed Era, then you are easily looking for a four-star match.

This is a six-man tag team match that could main event any pay-per-view, and would singlehandedly sellout an arena. The Undisputed Era may have a fourth member by the time they get called up though, as they have been seen trying to recruit Roderick Strong. While it is hard to see a perennial face like Strong aligning with a group of heels like the Undisputed Era, they could still recruit more men. Perhaps the Undisputed Era will be an army by the time they step foot inside the Shield's yard.
