#4 The Undisputed Era
The Undisputed Era may seem like a stable plucked from Ring of Honor!
Kyle O' Reily and Bobby Fish started off as reDRagon in ROH where they became three-time ROH world tag team champions. The inclusion of Adam Cole (BAY! BAY!) gave the duo much-needed star power.
The in-ring chemistry of Reily and Fish is unmatched and the duo also won the 2018 Dusty Rhodes Tag Team Classic tournament but the injury of Bobby Fish looked like a setback for the tag team champions.
They lost the NXT tag titles to the Moustache Mountain on the second day of WWE United Kingdom Championship Tournament event but won them back just two days later making them the second team after The Revival (Dash Wilder and Scott Dawson) to win the titles more than once.
A plethora of great matches and interesting storylines remains to be unfolded!
