#1 The Undertaker's streak gets conquered at WrestleMania 30

If you're a die-hard fan of The Undertaker, you have never watched this moment again considering it's so haunting to watch. 'The Phenom' faced Brock Lesnar at WrestleMania 30 in a dream match and despite the anticipation surrounding this bout, the match failed to deliver and most significantly presented the fans with a horrifying tragedy that is too hard to put in words.
Brock Lesnar conquered the streak of The Undertaker at the Super Dome and the whole arena went dead silent. 'The Phenom' is considered the greatest performer in WrestleMania history and seeing him fall down to Lesnar was nothing short of tragic.
There's no denying that The Undertaker still continues to be a WrestleMania attraction but the streak seemed like an unending prospect after 21-0. A lot of WWE fans hate Vince McMahon for pushing the envelope and even to this day, it is considered the most tragic moment in WrestleMania history.
