The Undertaker is WWE's most iconic character, but the time will soon come for him to step away from the squared circle. 

Mark Calaway is now 55. He's had a career in pro wrestling that has spanned over three decades. 

It's only natural for the WWE legend to be thinking of retirement - after all, his physical condition has been questioned for a few years now. 

Many believed 'Taker would be retiring at WrestleMania 33 when he left his hat and coat in the ring after being beaten by Roman Reigns. 

But fast forward three years and he's still wrestling a number of the big PPV events each year. 

Calaway has recently revealed in 'Undertaker: The Last Ride' that he was 'disgusted' with his performance in that match and that was part of the reason he decided to keep going. 

Now, he's explained how he wants The Deadman's retirement to go down - and it would be very fitting for his character. 

He told People.com:

"When you’re thinking of the old school Undertaker, that’s not a character that comes down to the ring and says, ‘Thank you for being with me for 30 years. It’s been a great career. I want to thank...’ 

Undertaker will soon step away from WWE

"That’s not what that guy does if you’re being true to the character and what people want to see.

"I’ve had this amazing career, I’ve been so blessed to have this career and far exceeded the expectations of when I got in this business.

"But I kind of want the John Elway ending, you know? The John Elway ending, when he went out and he won a couple of Super Bowls and then retired. 

'Taker wants to leave WWE when the time is right

"Or Peyton Manning, he wins the Super Bowl, then retired.

"When I’m looking at it, I want that match, that match when it’s just like, 'Oh yeah. Bam. I still got it. I got gas in the tank, I tore it down. Now walk away.'" 

You've got to admire Undertaker for sticking around in WWE until the moment is perfect. He's had some poor matches in recent years and it seems that hurts him more than anyone else. 

Undertaker wants to give fans one final perfect match

We don't know when that final match will come - perhaps Calaway doesn't either. But one thing is for sure: When it does roll around, it's going to be an epic conclusion to an iconic career.
