WrestleMania is a special occasion; one celebrated by every member of the WWE Universe. It is The Show of Shows, and anyone looking to make a name in WWE must rise to the occasion and perform on The Grandest Stage of Them All. But even the most special of occasions has something that further elevates it in the eyes of those watching and those participating. When it comes to WrestleMania, the event within the event is, unquestionably, The Undertaker’s Streak. ( UNDERTAKER'S WRESTLEMANIA PLAYLIST | ROAD TO WRESTLEMANIA PHOTOS)

The Deadman’s match at WrestleMania holds special significance. From his first appearance back in 1991 when he locked horns with WWE Hall of Famer “Superfly” Jimmy Snuka at WrestleMania VII, The Phenom has demonstrated dominance over opponents on a level never before witnessed in WWE history, culminating in an unparalleled 19-0 record.

So impressive has The Streak been that over the years it has taken on an almost mystical quality, furthering The Undertaker’s mysterious — and at times, terrifying — aura.

Over the course of his spectacular 19-year run, The Phenom has dispatched legends like Ric Flair, King Kong Bundy, and Jake “The Snake” Roberts, and he’s toppled monsters like Giant González and his brother, Kane ( WATCH). Even Mr. WrestleMania himself, WWE Hall of Famer and perhaps the best clutch performer in history, Shawn Michaels, fell victim to The Streak — he did so twice, in fact, and his second loss at the hands of The Undertaker ended The Heartbreak Kid’s career.

And yet, even something as big, even something as awe-inspiring as The Undertaker’s streak is perhaps best viewed through the smaller lens of certain unforgettable moments. Like the top-rope superplex of Ric Flair at WrestleMania X8 ( WATCH). Or The Deadman somehow sitting up after Jake “The Snake” planted him with not one, but two, DDTs during their match at WrestleMania VIII ( WATCH). The Streak has become so grandiose that even Undertaker’s entrance has become an event all its own.

When streaks last as long as The Phenom’s has, you can start measuring things of great significance against them. Over the course of his 19 years on The Grandest Stage of Them All, careers have begun and ended, Championships have traded hands countless times and the WWE has transgressed eras.

Despite it all, however, The Undertaker has been the one constant in the WWE Universe these past two decades.

Which leads us to the question on the minds of every member of the WWE Universe today: Can The Phenom extend The Streak to an unfathomable 20-0 when he enters WrestleMania XXVIII at Sun Life Stadium in Miami on April 1, 2012, against Triple H? That, well, we’re not yet sure of. So instead of speculate on the future, WWE.com has decided to take a trip to The Deadman’s past with this exclusive video playlist.
