#4 Mr. WrestleMania Streak

As mentioned earlier, The Undertaker had what will remain as the greatest streak in all of WrestleMania history, with it currently standing at 23 - 2. With The Undertaker now having lost at WrestleMania, there are a few more that currently have undefeated streaks at the grandest stage of them all, and none higher, pun intended, then Rob Van Dam.
While some current and former WWE stars have WrestleMania records standing at 1 - 0 or 2 - 0, Rob Van Dam's WrestleMania record currently stands at 4 - 0. RVD would defeat William Regal at his first WrestleMania at WrestleMania X8 for the WWE Intercontinental Championship, he retained the World Tag Team Championship with Booker T at WrestleMania 20, won the Money in The Bank Ladder match at WrestleMania 22 and teamed with Sabu, Tommy Dreamer and The Sandman to defeat the New Breed at WrestleMania 23.
RVD's WrestleMania record should have been higher even, as he was originally scheduled to team up with Kane at WrestleMania XIX in 2003 to defeat the Dudley Boyz and Tag Team Champions Lance Storm and Val Venis for the Tag Team titles.
However, due to time constraints over a Limp Bizkuit performance and Miller Light Cat Fight segments, the match was moved to RAW the following night. RVD and Kane did lose to Storm and Venis on the pre-show before WrestleMania began, but that counted as Sunday Night Heat, not WrestleMania.
