The main event of the show was an AEW World Championship match between Kenny Omega and Christian Cage. Omega retained his title at the show and The Super Elite, The Young Bucks, Doc Gallows and Karl Anderson, came to the ring to celebrate with Omega while attacking Cage.Luchasaurus and Jungle Boy came to the ring to save Christian Cage, but they were quickly outnumbered by The Super Elite. Kenny Omega cut a promo where he claimed that no one could defeat him. The lights went out and out came Adam Cole, whose contract with WWE expired recently. He teased an attack on Omega and co., but landed a superkick on Jungle Boy and joined hands with The Elite.But the best was reserved for the last as Daniel Bryan made a surprise debut at the end of the show, to a huge ovation from the fans. The former WWE star, who will use his real name, Bryan Danielson, in AEW, attacked the heel faction on his AEW debut.He cut a promo after the show went off the air where he praised his former employer, WWE, but stated that he joined AEW for the wonderful fans in AEW as well as the great matchups that he could have.
