5 WrestleMania main events that didn't involve a Championship

#3 The Undertaker vs Shawn Michaels

The Undertaker and Michaels

At WrestleMania 25, The Undertaker faced Shawn Michaels in what many deem as the greatest match in WrestleMania history. There were many who wished that this match headlined the show, instead of Triple H vs Randy Orton for the WWE title. This wish turned into reality at next year's WrestleMania, where Shawn Michaels faced The Phenom again, with the former's career on the line.

Edge vs Chris Jericho for the World Title and John Cena vs Batista for the WWE title took a backseat for the legendary duo, who closed out the show, with The Deadman putting down Michaels for good. The final image of the show was HBK standing in the middle of the ring, with 72,000 fans cheering for the fallen legend. This would be Michaels' retirement match, and he announced the same on the RAW after WrestleMania. Michaels did come out of retirement 8 years later, to reunite with Triple H in a winning effort against The Brothers of Destruction.
