The Undertaker's undefeated streak at WrestleMania is the greatest individual achievement in the history of professional wrestling.
It is a truly unique feat, as there will be many WWE World Heavyweight Champions for years to come, but there will never be anyone that could duplicate the streak.
The fact that The Undertaker participated and won in 21 consecutive WrestleManias was a testament to his talent, longevity, durability and dependability.
As with the case with most lengthy streaks, there are tons of statistics that can be taken away from it.
Before we jump into the numbers, let's we run through the cliché time capsule and take a close look at 1991, the year the streak began.
The president at the time was George H.W. Bush. The No. 1 song on the Billboard Hot 100 the day the streak began was "One More Try" by Timmy T. The price of gas in March 1991 was .72 per gallon. The Academy Award for Best Picture in 1991 went to "Dances with Wolves."
Now, let's jump into some numbers from the streak:
961,595: The amount of people that witnessed a match during the streak in person. Interestingly enough, the lowest attendance figure during the streak was The Undertaker's WrestleMania debut at WrestleMania VII (16,158), but the highest attendance figure was the final win during the streak at WrestleMania 29 (80,676).
5 hours, 45 minutes, 35 seconds: The total length of time of The Undertaker's matches during the streak. His longest match during the streak at was his Hell in a Cell match against Triple H at WrestleMania XXVIII, which clocked in at 30 minutes and 50 seconds. It was just six seconds longer than his epic encounter with Shawn Michaels at WrestleMania XXV. His shortest was once again his WrestleMania debut against Jimmy Snuka at WrestleMania VII, which lasted only four minutes and 20 seconds.
12: The amount former world champions The Undertaker defeated at WrestleMania. To clarify, I counted the men who had won the WWE or World Heavyweight Championships during their time in the WWE. The list consists of Diesel (Kevin Nash), Sycho Sid, Kane, Triple H, Ric Flair, Big Show, Randy Orton, Mark Henry, Batista, Edge, Shawn Michaels and CM Punk.
6: The amount of current WWE Hall of Famers The Undertaker vanquished during the streak. The illustrious list consists of Jimmy Snuka, Jake Roberts, Diesel (Kevin Nash), Ric Flair, Edge and Shawn Michaels.
2: The amount of times The Undertaker won a match by submission at WrestleMania. He defeated both Edge at WrestleMania XXIV and Triple H at WrestleMania XXVII with the Gogoplata.
The number two is also the number of times The Undertaker took part in a Hell in a Cell match at WrestleMania. The first came at WrestleMania XV against the Big Boss Man while the second came against Triple H at WrestleMania XXVIII.
18: The number of states in the union that witnessed an Undertaker match at WrestleMania during the streak. The state that witnessed it the most was California, as The Undertaker won in Los Angeles for WrestleMania VII, Anaheim for WrestleMania XII and Los Angeles again at WrestleMania 21. Only one Canadian province witnessed the streak, and that was Ontario for WrestleMania X-8.
3: The number of times The Undertaker won a world championship at WrestleMania. He first did it at WrestleMania 13, when he won the WWE Championship. The next two times came at WrestleMania 23 and WrestleMania XXIV, when he took home the World Heavyweight Championship.
The number three is also the amount of times The Undertaker's match closed the show at WrestleMania. Two of his world title victories occurred in the event's final match (WrestleMania 13 and WrestleMania XXIV), but his third and final main event took place at WrestleMania XXVI, when Shawn Michaels' career was on the line.
1: The number of The Undertaker's matches at WrestleMania that ended in disqualification. The lone disqualification finish during the streak took place against Giant Gonzalez at WrestleMania IX.
