The Young Bucks
On the August 17 episode of Dynamite, the Bucks revealed their mystery partner for the tournament to crown the first AEW World Trios Champions. Their partner was revealed to be Kenny Omega, who returned after a long time away while healing from injuries. They would win the Championships against Adam Page and The Dark Order (Alex Reynolds, and John Silver) at All Out. However, they were later suspended and stripped of them because of a real-life backstage fight that took place between Omega, the Young Bucks, CM Punk, and Ace Steel.
