#1 Refused to win- Randy Orton (Against The Undertaker)
The Undertaker holds the incredible streak of 21-straight victories at WrestleMania. But his streak wasn't meant to be this long.
Yes, the story dates back to 2005, Randy Orton struggled to make his name as he failed to become the new face of WWE. However, at that time, Orton had the opportunity to bring his career back on the track by starting a feud with The Undertaker.
So at WrestleMania 21, Orton was scheduled to take on The Phenom in a match.
Before the match, Orton was tossed with the idea of him ending Taker's WrestleMania streak. However, 'The Viper' Randy Orton passed the idea, saying he isn't ready for this kind of opportunity.
Therefore, Orton lost his match against The Undertaker at WrestleMania 21. And Taker continued his WrestleMania streak, making it 13-0.
Orton was called the 'legend killer' and the win would have gone well with him gimmick.
