It could be argued that no one has more Wrestlemania classics than The Undertaker, but even the phenom has a few self-admitted missteps.

In WWE's revealing docuseries The Last Ride, Taker watched his match against Roman Reigns at Wrestlemania 33. Undertaker wasn't in the best physical shape at that time, and the match suffered from a few botches along the way.

"It's like bloated Elvis," Taker reacted. "I feel bad for Roman. You dream about that match, to be in that match and tearing the house down and I wasn't able to give him that. That bothers me. He [was] probably looking at me thinking, 'What was that guy all about?' It was really disappointing."

In Dean Ambrose's infamous podcast with Stone Cold Steve Austin, he pulled back the curtain on his Wrestlemania 32 match with Brock Lesnar.

"I felt like I was pulling teeth. Brock didn't want to do anything, to be honest," Ambrose said. "I had a vision for that match to be the craziest thing imaginable. I was trying to pitch everything to everybody and had every idea and I put so much effort in and so much work in and other people did too... and I was met with laziness."

10 Most Emotional Returns After Career-Threatening Injuries

Mick Foley famously said that wrestling isn't about how many great matches you have... it's how many classic moments you can create. Few moments in pro wrestling can compare to a return after injury, especially when that injury threatens to end a top talent's career far too early.

Just think about the moment Edge returned to WWE at the 2020 Royal Rumble. His career had been over for nine years, he'd suffered a serious neck injury that require triple fusion surgery... it was an absolute impossibility for Edge to return, right?

"Once the music hit, and that reaction... I mean, I truly feel like I could have beat King Kong's ass," Edge told ESPN about his 2020 surprise return. "It was all surreal, kind of like a dream sequence, but everything's so focused and hyper-focused that I can't really explain it. But I think when you look at the video of me walking out, I think you see it in my eyes."

Iconic moments like these only come once in a while, but they're unforgettable every time! Check out these incredibly emotional moments when wrestlers returned after suffering career-threatening injuries.
