4. Chris Jericho forms the Inner Circle
During the main event of AEW Dynamite episode one, Chris Jericho and Santana & Ortiz took on The Elite. Moxley would debut and take out Kenny Omega, changing the match to a 3 on 2. Jericho pinned Matt Jackson after hitting him with the Judas Effect.
The trio would then beat up the Young Bucks before Cody Rhodes rushed in to save them. Sammy Guevara would then follow and align himself with Jericho and Proud 'N Powerful.
The run-ins continued with Dustin Rhodes trying to even the odds. However, Jake Hager would come to the aid of his future stablemates and beat down the Elite.
The five men stood together and towered over their foes. A week later, Jericho would announce that the five would be called "The Inner Circle" from then on.
3. Britt Baker vs Thunder Rosa - Lights Out Match
Britt Baker faced Thunder Rosa in one of the most memorable matches in Dynamite history. At the time, Baker was not Women's Champion yet, and Thunder Rosa still had to prove herself to the AEW audience.
The two wrestlers put on a grueling fight, which ended in a blood bath. Baker took a loss to Thunder Rosa, and the Mexican star stood triumphant. In one of the biggest twists of 2021, Baker was somehow more over after the loss. She'd use this momentum to build straight into defeating Hikaru Shida and becoming the Women's Champion.
