2012 The Shield
These three men Dean Ambrose, Roman Reigns and Seth Rollins would all go on to hold the WWE Heavyweight Championship. In fact, they once even all held it on one night. However, in November of 2012 few knew who they even were yet.
They all had plenty of success in NXT, but when they reached the main roster on that evening, it was a totally different gimmick and style as they attacked John Cena and Ryback to allow CM Punk to retain his own WWE Championship.
