#3 The Undertaker
The Undertaker has been a part of three of the four Saudi Arabia PPVs, missing only the last PPV, Crown Jewel, in October 2019. The Phenom featured on WWE television in SmackDown back in 2019 but hasn't returned since.
His last match on WWE television was back in July 2019 at Extreme Rules where he teamed up with Roman Reigns to defeat Drew McIntyre and Shane McMahon.
There's been talk about The Sting returning to WWE for one final match, which would most likely be against The Undertaker, but apart from that, The Deadman doesn't have any possible feuds for Super ShowDown.
The Fiend vs The Undertaker would be a dream match for many, as the two iconic characters are similar in a lot of ways.
A match against The Undertaker, and perhaps even a win, could only help push The Fiend even further on the Road To WrestleMania. This is one match that has to happen for The Fiend in the months to come, and Saudi Arabia could be a good place for it to happen.
