Anything can happen at the 'Showcase of the Immortals' and WrestleMania 36 this weekend should be no different.
While the show has been rescheduled to run for two nights and relocated to an audience-free WWE Performance Center in Orlando thanks to the coronavirus pandemic, there could still be some standout moments.
Scotland's Drew McIntyre attempts to climb a mountain and topple Brock Lesnar for the WWE Championship in a mouthwatering main event.
AJ Styles is intent on putting the Undertaker out of commission in a 'Bone Yard' match and Charlotte Flair will clash with NXT Champion Rhea Ripley.
If there's one thing we know from WrestleMania's past, it's that the results are far from set in stone - even just a matter of hours away from the event.
For more than three decades, the 'Show of Shows' has produced some of the greatest pro wrestling confrontations and memorable moments in WWE history.
But there have also been some upsets and truly shocking decisions along the way, so here's a look at five results that very few fans could have predicted.
5. The Nasty Boys rock the Hart Foundation (WrestleMania 7)
WWE tag team action was riding high in the early 90s when the Hart Foundation finally defeated Demolition in a best of three falls match at SummerSlam 1990 with a little assistance from new arrivals, The Legion of Doom. It is hard to underestimate just how popular the 'Pink and Black Attack' and the L.O.D. were during this time, and a dream match where Bret 'Hitman' Hart and Jim 'The Anvil' Neidhart could put their gold on the line against Hawk and Animal appeared to many as a blockbuster pay-per-view showdown in the making.
So, when The Nasty Boys were given a title opportunity against the Hart Foundation at WrestleMania 7, just a few months after signing with the company, most critics believed that this was purely a place-holder bout, designed to give the champions their first successful pay-per-view defence. As it turned out, those predictions were wrong.
With more than a little thanks owed to a motorcycle helmet, brought to the ring by their manager, Jimmy Hart, the Nasty Boys reigned supreme in a shocking upset. They would finally lose the belts to the Legion of Doom at SummerSlam 1991 and Bret Hart would go on to have one of the most successful singles careers in WWE history.
4. Sheamus kick starts his way to his first world championship (WrestleMania 28)
If you blinked during the opening contest of WrestleMania 28, you probably missed it! Sheamus set a new record for the quickest World Heavyweight Championship change in the history of the event.
In an upset that took less time to execute than the ring introductions, the writing was on the wall when Daniel Bryan took his eyes off the Celtic Warrior, to kiss his then on screen girlfriend, AJ Lee.
With the bell already rung, Sheamus capitalised on the situation and blasted the former American Dragon with a thunderous Brogue Kick as he turned around, gaining the pinfall, and his first world title.
Many fans had felt Sheamus had more than a fighting chance of defeating Bryan going into WrestleMania 28, but few could have predicted the breakneck pace in which he did it, and their outrage bolstered support for Daniel in the long run.
3. Triple H stings the Stinger (WrestleMania 31)
In the United States, Sting was for decades considered to be the biggest pro wrestling star to have never graced WrestleMania, so when he finally made his long awaited singles debut against Triple H at WrestleMania 31, it seemed to be a given that he would be victorious, but that's not what happened.
Following interference from members of D-Generation X, and the NWO, the 56-year-old fell victim to The King of King's sledgehammer and was pinned following a pedigree.
The match itself was a highly entertaining affair that saw the end of the NWO/DX rivalry, as all the participants shook hands in the ring following the contest. Still, for many of the Stinger's fans, it's a great shame that the icon's one and only WrestleMania match ended in a loss.
2. The Miz proves to be Awesome against John Cena (WrestleMania 27)
Making his return to WWE Monday Night Raw for the first time in more than seven years, The Rock was announced as the host of WrestleMania 27 in the run up to the WWE Championship clash between The Miz, and challenger John Cena. This seemed to create a scenario where John Cena would take the title from The Miz, leading to a challenge from The Rock. But it didn't quite go down like that.
The Miz came to WrestleMania to win, but when he and Cena ended up knocking each other out at ringside, the referee counted both men out. Not content with a double count-out finish for a WrestleMania main event, Hollywood's biggest movie star ordered that the match be restarted.
As Cena looked ready to put The Miz away with an Attitude Adjustment back inside the ring, The Rock got a measure of revenge after receiving the same move on the previous week's Raw.
He blasted Super Cena with a Rock Bottom, allowing The Miz to score what is arguably one of the biggest upsets in WresteMania history.
1. Triple H keeps Booker T down (WrestleMania 19)
WWE took control of WCW in 2001, but it did so without picking up the overblown contracts of icons like Sting, Goldberg, and Hulk Hogan. Arguably, the biggest star to make the initial move from the defunct WCW over to the thriving WWE was Booker T. As a former WCW Heavyweight Champion and WCW Triple Crown winner with a great look and abundant charisma, Booker seemed like the ideal man to dethrone Triple H at WrestleMania 19.
As the feud picked up steam, Ric Flair, now back with WWE as the manager of Triple H, offered Booker a job as The Game's limo driver. Surely, the constant belittling of fan-favourite Booker (with sinister undertones) could only result in the good guy getting his own back at Mania?
On top of all this, Booker had fought from the depths of a criminal past and a challenging upbringing following the death of both of his parents. How could he not come good, in this true underdog story?
Despite hitting Triple H with everything but the kitchen sink, The Game managed to end a hardfought contest by pinning the master of the Spinarooni with just one Pedigree. It was a deeply disappointing end to a story that had gripped millions of WWE fans and one of the worst examples of booking in living memory. Fortunately, Booker did later taste WWE heavyweight gold in 2006 with a victory over Rey Mysterio.
There will no doubt be more unexpected results, and amazing moments as an historic two-night presentation of WrestleMania 36 streams on WWE Network on April 4, and Sunday, April 5.
