#1 The Undertaker's streak comes to a shocking end
For 21 WrestleManias in a row, The Undertaker competed and won in WWE's biggest annual pay-per-view of the year and in the man's own words, 'The Deadman' has been "collecting souls" for almost two decades at The Grandest Stage of Them All.
However, at WrestleMania XXX in 2014, having initially accepted Brock Lesnar's challenge to a match at the event, The Undertaker was set for another highly-awaited clash against 'The Beast Incarnate'. And with fans considering 'The Deadman' to come out on the winning side, as usual, that wasn't the case to be.
In what is considered to be "the most shocking result in WWE history", The Undertaker, after 25 minutes of grueling battle with Lesnar and three F-5s, fell short to 'The Beast Incarnate', who ended the streak by defeating The Undertaker for the first time in WrestleMania history.
At one point, it did seem like The Undertaker would retire undefeated at 'Mania history, however, that wasn't to be, as the image of 'The Deadman' reflecting on the infamous 21-1 is probably the most powerful image to define the past decade for WWE.
