The Undertaker vs Kane
This all started at Survivor Series 2003 where Kane buried The Undertaker alive. At WM 20, Kane came out and he looked pretty confident that Taker is never going to return. Just then, the lights went off and Paul Bearer came out and after a few mystical manoeuvres, The Undertaker returned. Kane was still apprehensive and scream “I Killed You! You are not real!”
The Undertaker took the attack to Kane and beat him up viciously. Kane regained lost control and managed to deliver a Chokeslam to his brother but Taker kicked out and conveniently sat up. Taker then delivered his own Chokeslam to Kane and followed it up with a Tombstone piledriver for the win. With this, Taker went to 12-0 at WrestleMania.
