#7 The Undertaker vs. Kane

It had been teased for months, but when it finally happened, the look of shock and awe on the faces of everyone in attendance spoke volumes. In 1997, at the WWF's monthly In Your House pay-per-view, we witnessed the debut of a character that would prove to have tremendous longevity. During a match between Shawn Michaels and The Undertaker, fans saw the debut of Kane. Escorted by Paul Bearer, Kane walked to the ring as the Undertaker looked on in complete shock.
With presence and power that was only comparable to that of The Undertaker, Kane came in and beat down his brother, sending a message. The two men battled off and on for a number of years, and at other points even aligned with one another. However, the intensity of their feud is something that fans will remember.
