8. The Undertaker (Evolving With The Times Is King And Loyalty Pays Off)
When WWE present the annual Survivor Series Pay-Per-View on November 22nd, 2015, it will have been 25 years since The Undertaker made his in-ring debut with the company. That's an insane fact, and makes 'Taker the most enduring character in the promotion's rich history. First appearing at the same event in 1990, Undertaker has constantly evolved to keep himself relevant. The Undertaker offers long time fans a reminder of the nostalgia of their youth, but he does so whilst still maintaining a current credibility. Whenever the man wrestles, fans don't seem to chant things like, 'You've still got it', because Undertaker has never really lost it. He's as compatible now with the WWE system as he was back in 1990. That takes some doing. The guy's loyalty is also a key aspect just begging to be explored here. Having The Undertaker as a favourite performer shows that people admire that longevity, and willingness to do what is necessary for something they believe in. 'Taker has shown he's not adverse to hurting himself for WWE over the years, and his legions of fans respect that.
