#1 The Undertaker comes out and announces his retirement
The Undertaker has been arguably the biggest performer in the history of WrestleMania. His undefeated streak at WrestleMania was a record that I'm sure no one will ever replicate.
With that being said, even The Dead Man is helpless in front of his age and his body is definitely not in the best of shapes.
With the rumors of him already being retired from in-ring competition and constantly making out-of-character appearances in many events, it seems like the Phenom has finally decided to call it a day.
Though it can't be denied that without the Undertaker, WrestleMania would seem to be missing a huge part of its glorious history, the truth is that this has to happen eventually. And it might happen this year itself.
WWE is yet to announce or give any hint of whether The Dead Man would be appearing at the grandest stage of them all this year. In my opinion, WWE could be planning an impromptu appearance from the Phenom, only to announce his retirement from in-ring competition.
With all that The Undertaker has achieved in his career, he deserves a whole arena chanting his name and thanking him one last time before he makes his way back to The Death Valley once and for all.
