From WrestleMania 7 to WrestleMania 33, The Undertaker faced 21 different competitors at the Show of Shows, embarking on an unprecedented undefeated streak that lasted over two decades. Of course, some of those 'Mania matches were better than others (best forget about his encounters with Giant Gonzalez and Big Boss Man), but all them solidified their spot in history one way or another.
Earlier this month, The Deadman seemingly called it a career when he suffered only his second ever loss on the grandest stage to Roman Reigns. The 'Mania main event received its fair share of flack from fans who were expecting more from the contest, leaving them to wonder how much better the bout could have been had Undertaker's (mooted) final opponent been a certain someone else before plans changed.
Interestingly enough, Undertaker is no stranger to having the identity of his opponent switched months ahead of the event. Reigns might have been the last, but he was far from the first person to benefit from Undertaker's WrestleMania plans changing - with these seven matches being the most prominent instances.
