Check back the week of March 13th to see who the WWE fans have voted the Top 5 Underdog stories of WrestleMania history. These announcements will also be made in WWE arenas with the No. 1 Upset being announced the day of WrestleMania 22.

Very rarely does the champion walk into any match as the underdog, but that's exacty what happened at WrestleMania III when Hulk Hogan defended his WWE Championship against the undefeated Andre the Giant. Not only was Hogan able to end Andre's unbeaten streak, but was also able to get the big man up and over for a body slam.

Heading into WrestleMania III, Jake "The Snake" Roberts was one of the most-feared Superstars in WWE. Meanwhile, the Honky Tonk Man was a relative newcomer. In the end, it was Honky defeating Roberts. The Honky Tonk Man went on to gain the Intercontinental Championship soon after.

Randy "Macho Man" Savage needed three wins to get into the finals of the WWE Championship Tournament, while his opponent Ted DiBiase needed only three (due to a bye in the third round). Macho Man put his exhaustion behind him, though, and eventually landed his top rope elbow for the win and the WWE Championship.

Bret Hart defended the WWE Championship against Yokozuna in the main event of WrestleMania IX. But it was Hulk Hogan that walked away with the title. In a shocking turn of events, Mr. Fuji challenged the Hulkster to a match for Yokozuna's newly-won title. In the end, it was Hogan coming away with the win and the gold.

Heading into WrestleMania VII, nobody knew who Tenryu & Kitao were. That said, nobody thought they could actually beat the mighty Demolition. But in a match that lasted less than five minutes, Tenryu pinned Smash to shock the sports-entertainment world.

For years, Ted DiBiase disrespeted Virgil at every turn. Finally, Virgil had enough and challenge the Million Dollar Man to a match at WrestleMania VII. In one of the brightest moments of his career, Virgil was able to humilate DiBiase, beating him by countout.

For years, Owen Hart claimed he was living in the shadow of his brother Bret. At WrestleMania X, Owen rocketed out from behind his brother's shadow when he defeated him in the opening match of the show.

Both Triple H and Shawn Michaels have main evented WrestleManias in the past. Chris Benoit, on the other hand, was a stranger to the main stage heading into WrestleMania XX. The Rabid Wolverine's inexperience, however, didn't hinder him at all, as he eventually forced The Game to tap out to the Cripper Crossface.

Over the past year, John Cena has proved to be one of the best in the business. But heading into WrestleMania XX, few realized his true greatness. By the time WrestleMania XX was over, however, the Chain Gang was on a roll with the United States Championship around Cena's waist.
