#1 Kane
This is one of the most unexpected and underrated choices. Kane is The Undertaker's kayfabe brother. Since the late 90's he has been looked up to as a demon. He has evolved a lot over the years. But he still is wrestling.
He and The Undertaker are together known as 'The Brothers Of Destruction'. They have tagged-up, as well as they have fought each other on various occasions.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
Kane has the second best WWE debut ever after Chris Jericho's. In his debut, he walked out through fire pyros as a monster and broke into the Hell In A Cell, attacking The Undertaker.
That moment was made even better with JR's commentary. Kane has aged-up and is bound to retire soon. He can have a last match with The Undertaker and that could be the last match of The Phenom as well.
No matter what the result is, both could hang up their boots and make that moment forever remembered by us.
