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, showed villainous traits 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 to work for them all along. The Shield then quietly ended their association with Punk. At Elimination Chamber in February, The Shield defeated Ryback, John Cena and Sheamus. At WrestleMania 29 in April, The Shield won their first WrestleMania match against Sheamus, Randy Orton and Big Show. Two weeks later on Raw, The Shield defeated Team Hell No and The Undertaker, which would lead to Ambrose making his singles debut against the Undertaker on the April 26 episode of SmackDown, which he lost by submission. On the May 13 episode of Raw, The Shield's undefeated streak as a unit ended in a disqualification loss against WWE Champion John Cena and Team Hell No.
