Thanks to Mr. MiniMizer for compiling this report and sending it in:
WrestleMania 26 will be the first WrestleMania where an active and uninjured Triple H will not be wrestling for a heavyweight championship of any sort since WrestleMania 17. This was the longest active streak ever for a wrestler to contend for a heavyweight championship at consecutive WrestleManias in the history of the WWE. At WrestleMania 17, he fought Undertaker in a non title match. Since then, every match Triple H has had at a WrestleMania has been for a heavyweight championship.
WrestleMania 18 vs Chris Jericho for the Undisputed Title,
WrestleMania 19 vs Booker T for the World Heavyweight Championship
WrestleMania 20 vs Shawn Michaels and Chris Benoit for the World Heavyweight Championship
WrestleMania 21 vs Batista for the World Heavyweight Championship
WrestleMania 22 vs John Cena for the WWE Championship
WrestleMania 24 vs Randy Orton and John Cena for the WWE Championship
WrestleMania 25 vs Randy Orton for the WWE Championship
– Triple H was injured and did not wrestle at WrestleMania 23.
The new active streak for consecutive WrestleMania appearances wrestling for a heavyweight championship is John Cena, with WrestleMania 26 marking his sixth consecutive WrestleMania match wrestling for a heavyweight championship of some sort.
WrestleMania 21 vs JBL for the WWE Championship
WrestleMania 22 vs Triple H for the WWE Championship
WrestleMania 23 vs Shawn Michaels for the WWE Championship
WrestleMania 24 vs Randy Orton and Triple H for the WWE Championship
WrestleMania 25 vs Edge and Big Show for the World Heavyweight Championship
WrestleMania 26 vs Batista for the WWE Championship
The all time consecutive WrestleMania appearances wrestling for a heavyweight championship of some sort is still Triple H with seven, followed by John Cena with six, and Hulk Hogan who wrestled in six consecutive WrestleMania matches for the WWE Championship if you include the tournament as WrestleMania 4. He wrestled for the WWE Championship from WrestleMania 2 to WrestleMania 7, marking six consecutive WrestleManias.
Just a fun little tidbit I thought you and your readers may not have known off the top of their heads. Thanks for your time and love the website!
