#9 The Shield crash the party at Survivor Series 2012
The Shield and it's 3 members (Dean Ambrose, Seth Rollins, and Roman Reigns) defined this past generation, so their debut at Survivor Series 2012 has to be on this list. During a Triple Threat match for the WWE Championship between Ryback, John Cena, and CM Punk, the 3 NXT rookies came from nowhere and brutally assaulted Ryback, signalling that they were here to make an impact.
In their 3 years as a group, The Shield did everything imaginable, cementing their place as one of the greatest trios in WWE history. The moment of their arrival near the end of 2012 was shocking and incredibly refreshing. We'll get to the moment that the shattered the group later on, but from this point until mid-2014, these 3 men ran roughshod over all of WWE, and bringing up 3 new performers from NXT was done perfectly by WWE, making this one of the biggest and most important moments of the past decade.
