#21. The Undertaker vs. Batista - WrestleMania 23
Perhaps I'm biased because I was one of the 80,103 in attendance at Detroit's massive Ford Field, but I adore this match. The energy surrounding this match, the crowd EXPLODING when Taker won the World Heavyweight Title and extended his streak, it was perfect. The year before, Taker was in a very underrated match against Mark Henry, but it wasn't exactly a top tier bout, but this match was the moment that Taker's Streak became not just a big deal, but for many, the deal at WrestleMania every year.
The following year, he headlined the show for the first time since WrestleMania 13 and then the next four were massive matches with Shawn Michaels and Triple H that overshadowed the rest of the show. While he had an enjoyable rivalry with Edge troughout 2008, this match feels like the last time The Undertaker was a regular part of the show, it's the beginning of his rise to the godlike character he is now.
