5 WWE Superstars you didn't know wrestled inside the Elimination Chamber

This Sunday, the WWE Universe will enter the devil's playground one more time, as the company hosts the Elimination Chamber pay per view.

Since it's inception in 2002, the hellish structure has led to some classic moments and career-defining performances.

Who can forget Shawn Michaels returning from a career-ending injury to win the first Chamber match or any of Triple H's record-setting four victories inside the structure.

But for as epic as these moments were, there have been plenty of WWE Superstars who have flown under the radar.

Some Superstars, fans may have even forgotten entered the Elimination Chamber, though the pain their bodies feel will no-doubt remind said wrestlers.

Here are five WWE Superstars, you may have forgotten once entered the Elimination Chamber, and how they fared in the barbaric structure.

#5 Carlito

Carlito teamed with the Masterpiece Chris Masters inside the Elimination Chamber, before stabbing him in the back.

When Carlito debuted on SmackDown in late 2004, the young star couldn't have imagined he would end up inside the company's most barbaric match, just over a year later.

A champion of everything cool, Carlito may have been nervous entering the match, and these nerves weren't helped when he was entry #3.

Despite his unfamiliar surroundings, Carlito faired surprisingly well at New Year's Revolution 2006, eliminating both Shawn Michaels, who had won the first Chamber match in 2002, as well as his then-Tag Team partner, Chris Masters.

Making it to the final two, the former United States Champion would eventually have his good fortune ended by John Cena, who surprised his former nemesis with a roll-up, mere seconds after the Masterpiece's elimination, with Big Match John retaining the WWE Championship, he'd quickly lose to Edge.

#4 Vladimir Kozlov

Kozlov faced five World Champions in his Chamber match, though failed to score an elimination.

Kozlov's time in WWE was bizarre, to say the least.

Joining the main roster in 2008 on SmackDown, the powerhouse received a huge push, competing for the WWE Championship on multiple occasions, but never held the gold.

Whilst this push had fizzled out by the end of '08, Kozlov did find himself locked inside the WWE Championship Elimination Chamber match at No Way Out 2009.

Despite being a monster heel though, Kozlov failed to score any eliminations, though it's not hard to see why this is the case.

Locked up with Edge, Jeff Hardy, The Big Show, The Undertaker and victor Triple H, the WWE weren't ready to give Kozlov a huge elimination over any of these former World Champions, and instead, Kozlov was the second man eliminated, after a Last Ride from the Phenom.

#3 Test

Test scored two huge eliminations in the only Extreme Elimination Chamber match in 2006.

Andrew 'Test' Martin had plenty of stop-start pushes in WWE, so it came as no surprise when he was pitched as a big deal in 2006 in the revived ECW.

Entering the land of extreme as a heel, Test dominated over the competition and earned his spot inside the Chamber by defeating former ECW World Champion Tommy Dreamer.

But this was no mere Chamber, as the company touted the first ever Extreme Elimination Chamber, with all four pods holding a weapon as well as a Superstar.

Entering the even more dangerous structure at #4, the Canadian came armed with a crowbar and eliminated both Hardcore Holly and Rob Van Dam.

Being eliminated by Bobby Lashley, Test could only watch on as the Almighty also flattened the Big Show to become the new ECW Champion.

#2 R-Truth

R-Truth's biggest moment inside the Elimination Chamber came when he eliminated King Barrett at the pay per view in 2015.

He may be the current United States Champion (in his second reign), but it's clear that the WWE have never truly seen R-Truth as a main eventer.

Despite a brief flutter at the top in 2011, Ron Killings has firmly remained part of the mid-card, in entertaining and athletic matches.

This is why it will shock many fans to discover that Truth has been in four, yes four, Chamber matches.

Just to put that into context, Truth has competed in more Chamber matches than the likes of Batista, The Undertaker, Daniel Bryan, Jeff Hardy and Roman Reigns.

Whilst he may have never won one, Truth does have an elimination to his name, eliminating King Barrett during the 2015 Chamber pay per view, which saw Ryback capture the vacant Intercontinental Championship.

#1 Santino Marella

Santino somehow found his way inside the Elimination Chamber in 2012.

No-one in their right mind ever thought that Santino Marella would enter the Elimination Chamber.

But in 2012, the Milan Miracle did just that, after he replaced the injured Randy Orton in the SmackDown Chamber match.

Whilst few people believed Marella would win and enter WrestleMania 28 as World Heavyweight Champion, Santino did give it his all when he entered the match at #4

Eliminating Intercontinental Champion, the master of the Cobra would also eliminate Wade Barrett, leaving the match between him and Champion Daniel Bryan.

A former US, Intercontinental and Tag Champion in his own right, Santino was able to hold his own against Bryan, but was eventually caught in the LeBell Lock, with the Milan Miracle having no choice but to tap out.

The most unlikely Chamber entrant, Santino proved anything can happen in the WWE.
