The final pay-per-view before WrestleMania is the Elimination Chamber, and it has been since its inception in 2010.
Being the final show before the biggest event of the year, it is one that is often packed out with drama and excitement.
However, we are also used to seeing a few shocking swerves—moments that can set up legendary matches at WrestleMania or define careers.
Let's take a look at five of the biggest swerves in the short history of this fascinating PPV.
We start with a swerve that wasn't the most exciting in the world, but it certainly was dramatic. It happened in the Chamber back in 2012, as CM Punk successfully defended his WWE World Heavyweight Championship—in the early days of his mammoth reign.
There was just Chris Jericho, The Miz and Punk left in the match, and many expected The Miz to drop out, leaving Punk and Jericho to finish the match in serious style.
However, a shocking moment meant Y2J couldn't continue. Punk delivered a roundhouse kick to the head of the Canadian—which legitimately knocked him out. However, instead of just hitting the floor of the mat, Jericho fell out of the Chamber and landed on a cameraman.
It was carnage, and you can imagine the chaos backstage as most scratched their heads. Thankfully, Jericho recovered.
We stay with 2012 and a moment that came after the final Chamber match of the evening.
Daniel Bryan had just overcome the odds to retain his World Heavyweight Championship—although the competition wasn't great, with The Great Khali and Santino Marella as two of his opponents.
All the talk was whether the Royal Rumble winner, Sheamus, would choose CM Punk or Bryan to face at WrestleMania later that year. The WWE had drawn it out for a while, with Sheamus teasing feuds with both men.
However, we got our answer after Bryan's match. Sheamus caused a swerve by coming down and laying the champion out, indicating to everyone who he was choosing.
Whilst the World Heavyweight Championship lineup wasn't exactly stellar for the 2012 Elimination Chamber, Daniel Bryan's appearance in the 2013 edition featured far more star power.
However, nobody accounted for the winner. Jack Swagger came from left field to surprise the world and earn the title shot at WrestleMania.
He entered third in the match and didn't actually eliminate anyone until the end, when he sneaked behind Orton to capitalize—earning a stunning title shot.
Even though he didn't get the job done at WrestleMania, it was a shocking and surprising moment that amazed everyone.
The very first match at an Elimination Chamber PPV was in 2010, when John Cena beat Sheamus to once again win the WWE World Heavyweight Championship.
It was a pretty good match, in all fairness, and had some enjoyable spots throughout. However, what came next was an incredibly exciting and shocking moment.
Cena was doing his legitimate pose in the ring with his newly won championship when Vince McMahon's music hit.
He cut a fantastic promo and told Cena that the only way he would be going to WrestleMania was if he could beat one more man. Out came Batista to a huge pop, and an impromptu WWE championship match took place.
It lasted less than a minute, and all of a sudden, Batista was the new champion.
There can be little doubt over the most shocking moment in Elimination Chamber history. It was an enormous swerve between some of the biggest stars in WWE history.
Shawn Michaels had been campaigning for a match with The Undertaker for weeks, but Taker kept declining on several occasions, much to the frustration of HBK.
Taker was the world heavyweight champion heading into the show but was to be denied his title by an amazing swerve.
It was down to Taker and Chris Jericho in the final two, but nobody expected Michaels to crawl out from under the ring and drop the champion. Jericho stole a pin and won his third World Heavyweight Championship.
And, of course, Michaels eventually got his rematch. It was a remarkable swerve.
