On February 7, 2019 it was announced that Kenny Omega has signed a contract with the newly formed All Elite Wrestling federation; during the Las Vegas press conference to publicize the company's first pay-per-view, Double or Nothing, Kenny was attacked by his old rival and compatriot Chris Jericho, from whom he was later defeated at the event in the meeting that it would have decreed the challenger of Adam Page for the assignment of the AEW World Championship.
After the match they were both attacked by Jon Moxley. He became the first and only non-Japanese professional wrestler to win the G1 Climax, the promotion's premier tournament, when he defeated Hirooki Goto in the 2016 finals.
Throughout his career, Omega has also performed as part of larger national and international promotions, such as Ring of Honor, as well as independent promotions worldwide, including DDT Pro-Wrestling, Jersey All Pro Wrestling, and Pro Wrestling Guerrilla.
During a long interview with Sports Illustrated, he revealed he wants to be a true "best in the world" performer: "I want to be a true, all-around, real 'best in the world' performer," he said.
"That means singles matches, tag matches, mixed tags, battle royals, you have to be able to do it all. With AEW, I've been allowed the creative freedom to develop myself as more of an all-around performer. I had incredible chemistry tagging with Ibushi.
I asked myself, can I do it again with Hangman? I believe I can. Can I do mixed tags with Riho? How about a hardcore death match with Mox? That's the type of wrestler I want to be. And no, people have not got my absolutely strong suit yet, my forte, the main-event style singles match.
It's not that I've lost it, it's that I am building a tool chest from the ground up for a new audience. I want to do the hard work, setting the table for everyone to accept new faces. When it's time, which is sooner than people think, I'll remind people why I'm the best in the world," Omega added. "And it's coming. It's not a matter of if it's going to happen, it's just a matter of when."
