#13 His biggest fear is becoming a parody of himself

The Undertaker’s match against Goldberg at Super ShowDown prompted renewed talk amongst fans about when the WrestleMania icon will call time on his career.

He said his biggest fear is becoming a parody of himself and he does not want to overstay his welcome in the wrestling business.

#14 He could not remember his own name after WrestleMania 30

One of the biggest moments in WWE history came at WrestleMania 30 when Brock Lesnar became the first person to defeat The Undertaker at WrestleMania.

WWE released footage in 2015 of Vince McMahon calling for help when 'Taker collapsed after walking back through the curtain following the match.

Elaborating on that moment, the veteran revealed that he suffered a concussion five minutes into the match and he could not remember anything from 3:30pm on the day of the show until 4:30am the next morning.

He also had no idea what his name was and he could not remember his birthday.

#15 He does not blame Brock Lesnar for his WrestleMania concussion

'Taker said he has watched his WrestleMania 30 match back 10-15 times. He still cannot pinpoint where he got concussed but suspects it happened after one of Brock Lesnar’s German suplexes.

He does not blame Lesnar for causing the concussion, but admitted that the match knocked his confidence as a performer.
