Undertaker's Wrestlemania "Streak" is a career-spanning CMoA, but he has a few more.
Whenever he cleans house he takes on a huge amount of men and still beats them all.
Saving Miss Elizabeth and an injured Macho Man from Jake Roberts who was ready to hit them with a chair behind the entrance ramp then kicking Jake's ass at Wrestlemania 8.
Winning the WWF title from Hulk Hogan only a year of being in the WWF.
At King of the Ring 1998, The Undertaker met Mankind at a Hell In A Cell match, which is legendary for it's HSQ.
A lot of people see this (deservingly) as Mick Foley's Crowning Moment but Mick admits in his first book that Undertaker's immense expertise at what he does and professionalism that kept the match going after the infamous chokeslam through the cage. Also, both climbing the cell (twice) and then dropping from it to the ring with a broken foot is pretty badass.
His return at Wrestlemania 20, signaling the return of his "Deadman" persona.
His matches against Shawn Michaels at Wrestlemania 25 and 26, considered to be instant classics by many.
Any match he's had with HBK (the 1st Hell In A Cell, final two in the 2007 Royal Rumble)
Undertaker also gets one for calling Vince McMahon out backstage on the Montreal Screwjob. Long story short, he put Vince on the spot and said most of the talent would be prepared to walk out unless amends were made. He allegedly did it a few months later before Wrestlemania 14 (where WWF Champion Shawn Michaels was facing Stone Cold Steve Austin): he allegedly told Vince that if another screwjob happened, Vince would have to answer to him.
Also, so the story goes, told Michaels (who was complaining about having to lose despite a back injury that meant he would likely have to retire) that if Shawn didn't do the job, he would kick Shawn's ass. And then, to prove me meant it, made sure that he taped up his fists in Shawn's eyeline during Shawn's entrance. Claimed untrue by Michaels (though he has a history of Retcon), though appx 4:50 of this interview Undertaker did back in 2002, implies the story is at least partly true...
The Undertaker once participated in an Elimination Chamber... moments after being accidentally lit on fire.
Specifically, one of the bursts of flame that are part of his entrance went off almost directly underneath him instead of when he was already past, whether through timing issues or technical problems isn't know. Rather than (understandably) freaking out, he just tossed off his smoldering jacket, recovered from the stumble before emerging from the smoke and fog, and continued his unnervingly slow walk down to the ring.
The entire Ministry of Darkness gimmick, in this troper's opinion. The chilling speeches, the wardrobe, the awesome special effects and the comic book-like storyline were all proof that wrestling doesn't need to fool its audience into thinking its all real for it to still be So Cool Its Awesome.
When he appeared last of the 30 at Royal Rumble 2007 where The Great Khali entered at #28, punching out everybody in the ring. The Miz then entered at #29, getting thrown out as soon as he entered the ring. And then the buzzer sounded for number 30, then the gong sounded out, and the lights went out, the fans went BERSERK. Cue Undertaker beating the crap out of the Great Khali and cleaning the ring.
Taker's match with Triple H at Wrestlemania XXVII. The amount of punishment both men absorbed escalated to the point that Taker (who won the match by submission, of all things) was the one that had to be carted out of the stadium.
If it were possible to take it Up to Eleven, then their rematch at Wrestlemania XXVIII inside Hell In A Cell sure did. Among the many things 'Taker survived to win the match included a spinebuster on the ring steps, multiple sledgehammer shots to the face, over a dozen chair shots and a Sweet Chin Music from guest referee Shawn Michaels that was immediately chained into a Pedigree.
