#1 The Streak
Wrestlemania is the most significant show of the year for WWE, and it only happens once a year. The Undertaker holds the record for most wins at the event with an unprecedented run of 21 straight victories.
He sustained his first loss at WrestleMania 30 to Brock Lesnar then followed this with two wins at Wrestlemania 31 and 32 against Bray Wyatt and Shane McMahon respectively. He lost to Roman Reigns after five spears at Wrestlemania 33 in what pundits thought was his last match.

Despite the two losses at Wrestlemania, it is his impressive 21 consecutive victories at the show of shows that has separated him from every other WWE superstar.
The 21 wins, which came to be known as The Streak, is a unique statistic and will probably never be replicated by any other superstar. This streak began at Wrestlemania 7 when The Undertaker made his WrestleMania debut by quickly defeating "Superfly" Jimmy Snuka.
