The lights went out, and Cole showed up. It looked like he was there to confront the Elite, but he immediately turned heel when he superkicked Jungle Boy. He then embraced the Young Bucks and reunited with his friends from Japan.Adam Cole just knocked out Jungle Boy & hugged The Young Bucks. #AEWAllOut— Tim Jarrell of PWUnlimited (@TimmyBuddy) September 6, 2021The Elite and Adam Cole have a lot of history together, dating back to their time in NJPW. Surely, The Super Elite, as it is now known, will look to wreak havoc with the former leader of the Undisputed Era by their side.The part about the 'dead friend' refers to Adam Cole passing away on an episode of Being the Elite, the Young Bucks' YouTube vlog.Adam Cole wasn't the only one who debuted at the end of the AEW All Out main event.@WWEDanielBryan is here in #AEW!#AEWAllOut pic.twitter.com/oLBH975GP4— All Elite Wrestling (@AEW) September 6, 2021Just as it looked like another AEW show was about to end with The Elite standing tall, Bryan Danielson arrived, much to The Super Elite's horror.The former Daniel Bryan wasted no time in getting his hands dirty, as he repeatedly kicked Nick Jackson in the chest while the crowd chanted "Yes." With everyone else, including Adam Cole, out of the ring, Bryan delivered a vicious knee to Nick. He then celebrated with Jurassic Express and Christian Cage to end the show on a positive note.Adam Cole and Bryan Danielson are two huge acquisitions for AEW, and the buzz around the company has never been higher.
