#1 The Undertaker (WWE)
WWE has been through a lot over the last thirty years. From the rise and fall to Hulkamania to the company's top babyfaces getting incessantly booed, WWE has been through its share of ups and downs during the last three decades. But, there is an individual who has continued to define what WWE and the wrestling business standa for during that period and that man is none other than The Undertaker.
The Phenom made his WWE debut at Survivor Series 1990 and has been a feature in WWE Programming ever since.
A former WWE writer just went after JBL for his comments HERE
The Deadman has been with the wrestling company through the good, bad and worst times. During the Monday Night Wars, when every major Superstar in both the wrestling companies jumped ship, Taker remained loyal to Vince McMahon and WWE. Apart from being one of McMahon's most celebrated creations, The Undertaker has also been one of the most loyal soldiers of WWE head honcho. It wouldn't be a stretch to say that it is nearly impossible for a wrestler from the current generation to have the kind of longevity in the business that The Phenom has enjoyed.
While there have numerous instances where fans have questioned The Deadman for stepping back inside the wrestling ring, it is no secret that the fans still love to see The Undertaker perform. The fact that the most talked-about match from WrestleMania 36 was the Boneyard Match between Taker and AJ Styles goes on to show he is still relevant. When it comes to the wrestling business, The Undertaker is the very definition of loyalty.
