#3 – The Wyatt Family vs The Shield
In the early 2010s, two groups debuted on the main roster, taking the WWE Universe by storm. The Shield made their first appearance at Survivor Series 2012, helping CM Punk retain the WWE Championship by attacking Ryback, allowing Punk to pin Cena and retain the belt. For the next two years, Roman Reigns, Seth Rollins, and Dean Ambrose laid waste to the entire main roster, running through top stars like John Cena, Randy Orton, Sheamus, and Daniel Bryan.
By the time 2013 came around, another terrifying trio debuted on the main roster, dubbed "The Wyatt Family." Bray Wyatt, Luke Harper, and Erick Rowan would also make quick work of anyone that came in contact with them. Kane, Kofi Kingston, CM Punk and Daniel Bryan were only a few of a long list of names that felt the wrath of the trio. As they continued to build, and the Shield suddenly turned face, the WWE Universe began to ask one question.
WHEN ARE WE GOING TO SEE THE WYATT FAMILY FIGHT THE SHIELD?
It was a slow burn to that run. The Shield rallied around Daniel Bryan, who had been the target of the Authority for half a year by this point. At the same time, Bryan had been targeted by The Wyatt Family, who tried to indoctrinate him after he repeatedly lost opportunities at the WWE Championship. Bryan eventually broke away, and after the Royal Rumble PPV would look to make a move towards the title yet again, leaving the Wyatts with nothing to do.
Finally, with the Wyatts and the Shield looking to earn a shot at the Elimination Chamber, the two groups finally butted heads, leading to a match at Elimination Chamber, which saw the Wyatts emerge successful. At this point, cracks began to appear in the Shield, as all three members became visibly frustrated with each other.
Two weeks after Elimination Chamber, and the Wyatts put away the Shield once again.
With two back-to-back losses, it looked like the Shield wouldn't be able to overcome the ominous force that was the Wyatt Family. However, months after their feud began, the trio finally got back on the same page, and put away the Wyatts...on an episode of Main Event.
It ended with Dean Ambrose pinning Erick Rowan after the Dirty Deeds v.1, but by this point in the year, the Shield had already moved on to bigger and better things, looking to take on a reformed Evolution after WrestleMania.
Considering that these were two of the most dominant forces in the entire WWE for a few years, it's pretty shocking to see how quickly it was wrapped up. After all, most of the fanbase hasn't even seen the final match in the series, and that's not the right way to end an epic feud between these two factions.
