The Shield may be one of the most dominating factions in the history of WWE. Seth Rollins, Roman Reigns, and Dean Ambrose ran through the company, first as an arm of The Authority, then as a force against it.
The faction made stars out of all three men, and they have all gone on to have immense success. Ambrose, now wrestling as Jon Moxley in AEW, is the first two-time AEW World Champion in company history. Rollins is a former WWE and Universal Champion.
Reigns is on possibly the best run of his career as the WWE Undisputed Champion, holding both the Universal and WWE titles simultaneously. At Royal Rumble 2022, however, he was just the Universal Champion. And he met his former stablemate in Rollins.
