#4. Return of the Undertaker
Even though most of the WWE fans want The Undertaker to call it a day in his career, his presence can still give goosebumps to them. At Wrestlemania 33, The Undertaker symbolically retired from WWE - or at least fans thought he did so. Thus, when John Cena began taunting the Undertaker and called him for a match at Wrestlemania 34, some fans did not expect the deadman to make a return, especially since he barely had a good match after his Hell in a Cell 2015 encounter against Brock Lesnar.
However, the deadman did appear at Wrestlemania 34 and laid waste to his challenger John Cena. The 16-time world champion was squashed in a few minutes by the phenom. The Undertaker also had a casket match against Rusev at the Greatest Royal Rumble; singles match against Triple H at the Super Show Down, and a tag team match with Kane against DX at WWE Crown Jewel.
