The Undertaker has done it all during his incredible 30-year WWE career.
He's become pro wrestling's greatest icon and had some of the most memorable matches in history.
But who does The Deadman rate as his favourite opponents?
Well, in the 'Last Ride' documentary, he was asked just that and named six men who helped his career and inspired him to keep going.
"I've been in the ring with some really great guys," Undertaker said, per Wrestling Inc.
"I had some great matches with some great people. There's a lot of guys obviously on that list. But, if you try to get me to narrow it down... [an image of Bret Hart appears on-screen]
"Bret was smooth as silk. Everything that he did look really good. He was one of the first guys that I got to expand the character with, and show that I was more than just a gimmick.
"He always raised the bar."
While many of 'Taker's matches in WWE came against other 'big guys', he actually admitted that Kurt Angle was one of his favourite 'smaller' opponents.
"I enjoyed working with the guys that were smaller," he continued, speaking of Angle.
"It was easier for me in the sense of storytelling. They were always bigger than life in the size discrepancy."
Talking of big guys though, Undertaker also named Batista as one of his favourite challengers and believes their clash at WrestleMania 23 should have been the main event.
"My match with Batista. Two big guys that aren't thought of having the match of the night. I really enjoyed that match."
There was also time for 'Taker to name a legend in the form of Ric Flair, saying he picked working with The Nature Boy over an 'up and coming talent' at WrestleMania 18.
"I remember it was WrestleMania in Toronto. I didn't have an opponent," The Phenom recalled.
"Vince [McMahon] came to me and asked, 'Would you like to work with this guy, who is up and coming, or would you like to work with Flair?' I said, 'I wanna work with Flair!'"
The Deadman rounded off his list by name-dropping Triple H and Shawn Michaels, saying he's most proud of the matches he had with those two at four straight WrestleMania events.
"One of the things that I'm proud of is the two matches I had with Shawn, and the two matches I had with Triple H," he said.
"It's very seldom that you get to tell a four-year story. I look back at everything as far as 'Mania - those four matches are going to be right up there as some of the best things that we ever did."
These days, it's an honour for any wrestler to have a match with The Undertaker.
But the man himself enjoyed working with Hart, Angle, Batista, Flair, Triple H and HBK more than anyone else.
