#4 The Undertaker
For whom the bell tolls! Those are the words that came to mind during the entrance of The Undertaker. During his twenty-five years in the ring, he had memorable feuds with the likes of the late Yokozuna, Diesel, Shawn Michaels and 'Stone Cold' Steve Austin. He also underwent reinvention along the way. At one point, he completely abandoned the Dead Man character and embraced being an American Bada**, a biker character he committed to with equal effort.
One of the greatest accomplishments that Undertaker was known for was his twenty-one-win streak at Wrestlemania. He captured championships, was both a face and a heel, and through it, all remained an iconic figure in the promotion's history. His commitment to his character was complete. Today, many have speculated that when he left his cap, coat, and gloves in the ring last year after losing his Wrestlemania match up it symbolized his retirement. He was most recently seen as part of the WWE's Raw25 program.
