.Who is the The Shield in the WWE? They were a professional wrestling stable that consisted of Dean Ambrose, Roman Reigns and Seth Rollins. The Shield debuted at WWE Survivor Series on Nov 18, 2012. They basically began as Mercenaries for CM Punk when they interfered in a triple threat match between CM Punk, John Cena, and Ryback.
The Shield would become a dominant force within the WWE. They were supreme in 6 man tag team matches and won several titles along the way. Originally, in the WWE, The Shield were a heel team. This changed over time as they turned face and feuded with the HHH, Batista and Randy Orton. This would essentially be Shield vs Evolution series of matches.
The Shield first broke up when Seth Rollins turned on his teammates and join HHH's authority stable. Both Dean Ambrose and Roman Reigns would go their separate ways. The Shield reunited in WWE several times over the years but either due to injury, nothing was long-term.
Recently, A Full Fledged Reunion of The Shield in WWE was underway when a returning Dean Ambrose and Seth Rollins interfered as Braun Strauman tried to cash in his MITB Contract. As did others, this reunion was short-lived as on the Oct 2nd Raw, Roman Reigns revealed that he was suffering from Leukemia and relinquished the WWE Universal Title. Dean Ambrose turned heel the same night and seemed to put a final nail in the coffin of The Shield in the WWE.
