AEW star Bryan Danielson (F.K.A. Daniel Bryan) is one of the all-time greats. The Leader of the 'Yes!' movement has been one of the top names in WWE throughout the past decade, winning all available titles and creating a legacy as the Ultimate Underdog.

Danielson had retired once in 2016 due to a neck injury. However, he returned to in-ring competition two years later.

The 40-year-old was a regular competitor on SmackDown. At WrestleMania 37, he faced Edge and Roman Reigns in a Universal Championship match but came up short. The Tribal Chief emerged victorious after pinning both his opponents at the same time.

On the April 30 episode of SmackDown, Danielson challenged The Head of the Table to a Career vs. Title match. Again, the Ultimate Underdog failed to defeat Reigns. Following that, Danielson stayed off-screen and his WWE contract expired on May 4.

Bryan Danielson recently signed a contract with AEW. He made his AEW debut last Sunday on the All Out pay-per-view. On AEW All Out post-show media scrum, the former WWE Champion spoke about leaving WWE and his relationship with Vince McMahon.

"WWE was so gracious with me as far as the offer that they gave me. They were gonna let me go do some other stuff on the outside, but, I hate to say this, Vince sometimes - he and I have a great relationship. I love him, I do. Sometimes he's overprotective of me," Danielson said.
