#3. WWE fans don't want to see return: The Undertaker

Despite a less-than-flattering WWE run between 2014 and 2019, The Undertaker managed to end his career in the best way possible in 2020. Not only did he face one of the best of this generation in his final match against AJ Styles, but he returned in a big way, and his appearance as The American Badass in the cinematic Boneyard match marked a fitting conclusion to his incredible career.
It was only apt that 30 years after his debut at Survivor Series 2020, WWE held a final farewell for The Undertaker. After years of teasing retirement, The Deadman finally ended his WWE career with an unprecedented three-decade-long run.

It's a legacy that will never be touched, and his final farewell means that it doesn't make sense for him to come out of retirement yet again for a WrestleMania match. The reality is that WWE doesn't need The Undertaker for WrestleMania anymore, even if he is the greatest Superstar to ever compete at the event.
