#4 The Undertaker makes an unannounced appearance at WrestleMania and makes quick work of John Cena
In the lead up to WrestleMania 34, WWE ran a story-line in which John Cena was without a match at WrestleMania. When Cena failed to win the Elimination Chamber match and his WWE Championship match at Fastlane, the chances of Cena competing at WrestleMania looked very bleak and slim.
Cena decided to challenge The Undertaker to a match at WrestleMania. However, 'The Champ' never received a response from the Deadman. Cena battled with Kane too, but The Undertaker was nowhere to be seen. The sixteen-time world champion announced that he would go to WrestleMania as a fan and would watch all of the action from the crowd.
About an hour into the main show at WrestleMania, Cena ran backstage after the referee communicated with him. He came out later in the show in his ring attire, ready for a fight. However, Cena didn't get what he wanted when Elias came out and did his usual shtick. The Champ took out Elias and walked up the ramp.
Just as it looked as if 'Taker wasn't going to show up, the sound of the gong went off and The Phenom made his awe-inspiring entrance. Cena was stunned as Taker made his entrance and stared holes through him. As the bell rang, Undertaker took the fight to Cena. Cena mounted barely any offense as The Undertaker Tombstone Piledrivered him to the depths of hell in under 3 minutes.
