#2 The Undertaker
If it feels like we go through this every year, it's because we do. Ever since WrestleMania 27 in 2011, fans have speculated which instalment of the Show of Shows would be The Undertaker's last, but it truly does seems as if the end is finally near.
Of course, nothing has been officially announced by the Undertaker or WWE in regards to this being his last 'Mania, but the writing is on the wall with his opponent being Roman Reigns. The Phenom will more than likely put over the fresher face and descend back into the darkness for good.
Again, it is very possible Undertaker will resurface yet again next year, but why do that when he has already suffered two defeats at WrestleMania? If this upcoming instalment does indeed mark the end of The Deadman, here's hoping he goes out on top.
