#4 The Undertaker's gong

The Undertaker has entertained us for more than 25 years and still carries a magnetic aura whenever he appears on-screen. The Phenom, despite snubbing John Cena's challenge for a match at WrestleMania, is sure to appear at the Super Dome on Sunday.
The Undertaker carries a strong personality and has helped make WrestleMania what it is today. Considering the rumors that have been doing the rounds, a phenomenal comeback in New Orleans would get the crowd on its feet.

John Cena will also be there as a fan, and since this match is indeed rumoured to happen at 'The Show of Shows', the company could be looking to surprise the audience with a last-minute appearance from The Deadman.
