#5. AJ Styles and The Undertaker

We all know that The Undertaker is Vince McMahon's greatest creation and the Chairman of will do absolutely everything to keep The Phenom's character sacred.

Since his on-screen persona is so distinct from the other performers on the roster, it would be very weird to see anyone in the WWE ever acknowledging it on live television.
Even though The Phenomenal One did share the ring with The Undertaker for a special segment before the Survivor Series in 2016, the two have never faced each other inside the squared circle, let alone WWE.
However, this does not restrict the two from keeping tabs on each other's life. In an interview with Inside the Ropes, the former WWE Champion gave us an insight on his relationship with The Phenom.
"I can tell you I was emotional because he's my friend. He and I have got a relationship between both of us have the same friend that we're very close to, so he and I developed this relationship without even knowing each other that well. But it was heartbreaking a little bit because this is the guy that's been here for so long and has shaped the WWE into what it is now.
