In November 2012, Ambrose made his main roster debut at the Survivor Series pay-per-view event alongside Roman Reigns and Seth Rollins, as they delivered a triple powerbomb through an announce table to Ryback during the triple threat main event for the WWE Championship, allowing CM Punk to pin John Cena and retain the title. The trio declared themselves The Shield and routinely emerged from the crowd to attack Punk's adversaries, including Ryback and the WWE Tag Team Champions Team Hell No (Daniel Bryan and Kane). This led to a six-man Tables, Ladders, and Chairs match being set up for the TLC pay-per-view event on December 16, where Ambrose, Rollins and Reigns defeated Team Hell No and Ryback in their debut match. The Shield continued to aid Punk after TLC, both on Raw and at the Royal Rumble in January 2013. The night after the Royal Rumble, it was revealed through footage that Punk and his manager Paul Heyman had been paying The Shield and Brad Maddox to work for them all along. The Shield then quietly ended their association with Punk while a feud with John Cena, Ryback and Sheamus led to a six-man tag team match at Elimination Chamber, which the Shield won. The Shield had their first match on Raw the following night, where they defeated Chris Jericho, Ryback and Sheamus. Sheamus then formed an alliance with Randy Orton and Big Show to face off The Shield at WrestleMania 29 in April, where the latter emerged victorious. Two weeks later on SmackDown, Ambrose made his singles debut against The Undertaker and lost by submission. On the May 13 episode of Raw, The Shield's undefeated streak in televised six-man tag team matches ended in a disqualification loss against WWE Champion John Cena and Team Hell No.
