#3 Jon Moxley a.k.a Dean Ambrose (Doesn't Own)

Jon Moxley's debut in AEW was probably what set the world on fire. For weeks, it was speculated where Dean Ambrose would go after his WWE contract expired. At AEW Double or Nothing in 2019, the former WWE Champion made his debut by attacking Kenny Omega and Chris Jericho and creating one of the year's most significant impacts.
Months later, he figured into the AEW World Championship scene with a long-drawn-out feud with Chris Jericho and The Inner Circle. The feud was the true epitome of a babyface overcoming the odds against a dastardly heel and his brutal stable. After winning the AEW Championship at AEW Revolution, Moxley cut a passionate, unscripted promo that spoke of his love for the fans.
As Dean Ambrose, it wasn't the same. While he was part of The Shield and won multiple WWE Championships, Moxley just felt that WWE didn't get his character right. He thought that the scripted promos didn't help, and his booking was not good. He did appreciate his time with the company, but he has inferred that Ambrose is a WWE creation while Moxley is his real face.
Jon Moxley was the name he was using when he first started wrestling, and in 2020, he filed trademarks for the name. It seems that Moxley will be seen for some time to come.
#2 Chris Jericho (Does Own)

Chris Jericho has always been Chris Jericho. He has kept the name throughout most of his wrestling career and has had the privilege of wrestling for WCW, ECW, WWE, and AEW under that name. He used the name in films with his most recent outing in Jay and Silent Bob Reboot.
As a performer, Chris Jericho has been able to showcase his skills, and at age 49, he is still showing that he is one of the best in the business. His reasons for leaving WWE are quite well known, and a career resurgence in AEW is also a testament to his creative instincts.
Chris Jericho, as AEW Champion, was a piece of good booking by Tony Khan. Having the right heel will set the stage for the babyface who would take the title away from him, and Jericho was more than up to the task. Jericho was also able to get his first stable with The Inner Circle.
Jericho has not hinted when his time in the ring will be up, but his recent match with Orange Cassidy insinuates that won't be anytime soon.
