Now that The Undertaker's famous undefeated streak has ended, we can now look back it in its entirety. In the days leading up to WrestleMania 31, we will take a look back at every memorable chapter of the feat that can never be duplicated. Here's a look at what became the holy grail of professional wrestling.

The Undertaker vs. Ric Flair (10-0)

WrestleMania X-8 | Skydome (Rogers Centre) — Toronto, Ontario | March 17, 2002

Attendance: 68,237

Match length: 18:47

By 2002, The Undertaker had already vanquished two men that would eventually become WWE Hall of Famers at WrestleMania in Jimmy Snuka and Jake Roberts.

But perhaps the most notable opponent The Undertaker has encountered at WrestleMania was Ric Flair at WrestleMania X-8 (or 18 for us normal folks).

Think about that for a second: The Undertaker went against Ric Flair one-on-one at WrestleMania, and it wasn't even the semi-main event on that particular card. The match was pretty much smack-dab in the middle of the show, although it was given significant time, clocking in at 18 minutes and 47 seconds.

Granted, the WWE had more big names than it knew what to do with at this point, which brought about the brand split soon after this show, but I still believe a match between these two icons could have been made a much bigger deal.

The story behind the match itself wasn't about two legends squaring off to see who's the best like The Rock-Hulk Hogan match everyone remembers from this show. This was a personal rivalry that started when Flair interfered in The Undertaker's match against The Rock at the prior pay-per-view, No Way Out.

The Undertaker, being a heel, then bullied his way into a grudge match against Flair by beating up his family members and friends.

In Flair's first WrestleMania match in 10 years, he didn't even complete his elaborate entrance because the rivalry had become so intense. The Undertaker played the bully role so well as he dictated the pace against the smaller Flair.

That story was also told well on commentary, as Jim Ross frequently admonished The Undertaker and referred to him as Booger Red.

(For those that don't know, Booger Red was in reference to former University of Texas linebacker Tommy Nobis, who Ross was very familiar with as he is an avid fan of the Longhorns' chief rival, the Oklahoma Sooners. Since The Undertaker has naturally red hair, I guess Ross thought of Nobis' Booger red nickname when saw him.)

Flair had fleeting moments of hope throughout the match, including an assist from Four Horsemen partner Arn Anderson, but The Undertaker routinely cut those moments very short and won with a tombstone, which was something he rarely did during his biker days.

This was not a technical masterpiece between two legendary wrestlers. This was a bloody brawl from start to finish. Although it was mostly one-sided, it was yet another entertaining chapter in The Undertaker's undefeated streak at WrestleMania, which hit double digits on this faithful in Toronto.
