#3 The O.C. vs The Undisputed Era

The O.C. was formed soon after WrestleMania 35 last year when AJ Styles turned heel during a match with Ricochet on RAW. Styles quickly turned into one of the most hated villains on the WWE roster and fans immediately began speculating on a dream feud that they had been clamoring to see for a while: The O.C. vs The Undisputed Era.
Adam Cole's faction had made a name for itself down in NXT and many were hoping that WWE would give them a multi-man match featuring the two factions at Survivor Series.
The seeds were planted for a future match back in June 2019 when the two factions engaged in a short-lived Twitter war. Styles found comparisons between the two stables hilarious, which garnered a response from Cole and other members of his faction.
Months later, The O.C. brutalized The Undisputed Era during an NXT invasion, but we have yet to witness an all-out feud between the two stables, that would culminate in a dream match for the ages.
