The Undertaker's winning streak at WrestleMania is something of a phenomenon - no pun intended.
At 21-0, it's no surprise that talk of who he's facing on the grandest stage of them all dominates the proceeding weeks and months leading up to the event - often overshadowing other big match-ups and world title contests.
'The Phenom' is a class act. It's important to get that in early. He has been one of the very best in the business for years, and for that reason still commands a quality opponent when the Pay Per View audience is at its biggest.
This year is no exception, and whilst Brock Lesnar might not be the most technically gifted of wrestler out there, but he certainly offers something a little different to the previous opponents that have fallen in-front of 'The Deadman'.
Having won the UFC Heavyweight Title, his name is well known outside of WWE circles as well as in, and that could help command an even greater audience on April 6th in New Orleans. And, pairing these legitimate fighting credentials against the greatest record in wrestling is a wise move by Vince McMahon.
But, if Lesnar is to claim something bigger than a belt - the '1' in the loss column against The Undertaker - then he'll have to defy history; and anger a lot of fans in the process. He's not the most popular wrestler in the organisation, and injured himself in a big match at WrestleMania XIX just over a decade ago. However, plenty of time has passed since then, and he's as good as anyone for this fight.
So, just what does The Undertaker bring to the table at WrestleMania? Well, the official WWE Magazine have pulled together some of the streak's key facts, and here's the best of them:
1. Most matches at WrestleMania - 21
The Undertaker is ahead of some famous names when it comes to fighting on the biggest stage, with Shawn Michaels and Triple H - two people he's beaten at WrestleMania - next on the list at 17 appearances apiece.
2. Pay Per View victories - 91
It's not just at WrestleMania that The Undertaker performs. It might be the event that he's best known, but he's claimed victories at pretty much every other PPV in the industry.
3. Other Wrestlemania streaks - 8 undefeated
The Undertaker's might be the greatest streak, but it isn't the only one. Looking at wrestlers to have been in more than two WrestleMania contests, The Miz and Rob Van Dam are both undefeated at 4-0. Four others are at 3-0, whilst Rick Rude is 2-0-1.
4. Longest match - 30:41 v Shawn Michaels
The Undertaker's match with Shawn Michaels at Wrestlemania XVX was his longest at just over 30 minutes, whilst his fastest was his first, against Jimmy Snuka.
5. Cage King - 2 wins
There have been three cages at WrestleMania, two in the form of 'Hell In A Cell'. The Undertaker has won twice inside the steel shell, beating The Big Boss Man and Triple H.
6. Losing Streaks
If The Undertaker is the best, then a few can throw there hand up as the worst. Jeff Hardy and Goldust are 0-5, whilst Vince McMahon is 0-4. Tito Santana lost seven times in seven consecutive appearances after winning his first, making his the longest losing streak at 1-7.
