#1 Bray Wyatt

Some of the previous Superstars on this list have not had much luck at WrestleMania before this year, but Bray Wyatt's tale is a sad one. He lost to The Undertaker, Randy Orton, and John Cena at the Show of Shows in the past, while also being beaten up with ease by The Rock and Cena.
Wyatt's luck at the Show of Shows was rotten, until this year. In an act of revenge for his first WrestleMania defeat, the Eater of Worlds invited John Cena into the Firefly Fun House for one of the most bizarre and entertaining matches in WWE history, if you can even call it that.

The entire match likely was Bray Wyatt's brainchild, slotting in loads of references and inside jokes that rewarded long-time WWE viewers. Cena was trapped in this wacky world, where Wyatt manipulated him perfectly.
It was a cinematic masterpiece and after tossing around the 16-time World Champion physically and especially mentally, The Fiend appeared to finish him off. And thus, he turned the tables on the "most overvalued, overhyped and overprivileged WWE Superstar in existence".
Bray Wyatt got his WrestleMania win back from John Cena in the most outlandish way possible. This was his masterpiece and more importantly, this was his moment. He's truly got the whole world in his hands.
