25 Most Important WWE Stars Of The 21st Century So Far

21. Kane

It would be hard to make a list of this type without including Kane, who has been almost a permanent member of the WWE roster for the entirety of the 21st century. Some of his rivalries with The Undertaker at the beginning of the century were outstanding, and with the inclusion of Paul Bearer being thrown into the mix, you had one of the most memorable feuds in WWE history on your hands. When he is fully unleashed by the WWE, it is safe to say he is at his very best. Even recently he managed to destroy Zack Ryder's push by brutally taking him apart - and that was vintage Kane, as Michael Cole would say. He's a guy who has managed to maintain the same gimmick for well over a decade, and that alone makes him hugely important to the WWE.
