#4 The Shield (every member won a World title)
The Hounds of Justice were destined for greatness from day one and were treated as a big deal on the WWE roster as soon as they debuted at Survivor Series 2012. Seth Rollins, Roman Reigns, and Dean Ambrose were originally heels. They turned babyface on the Road to WrestleMania 30 in 2014 and engaged in a feud with the newly-reformed Evolution after the event. During this feud, Seth Rollins turned on his stablemates, and thus The Shield disbanded.
Rollins won his first World title in the main event of WrestleMania 31, by cashing in his Money In The Bank briefcase. In May 2016, Ambrose won the Money In The Bank briefcase and went on to cash it in on Rollins on the same night to become WWE World Champion.
Reigns was the breakout star of The Shield and WWE pushed him as a megastar for the next few years. Reigns won 3 World titles and a Universal title as well. He went on to headline four straight WrestleMania events from 2015 to 2018.
