The World Heavyweight Championship was introduced in 2002, and it was first won by Triple H. In all, there would be 55 different reigns, with 25 different superstars winning it at some point.

But the World Heavyweight Championship was retired at the 2013 TLC: Tables, Ladders & Chairs pay-per-view. That night, Randy Orton defeated John Cena, and both the World Heavyweight and WWE Championships were unified into one: The WWE World Heavyweight Championship.

It's already been six years since the World Heavyweight Championship was retired by WWE. But it's always a fun time to look back and reflect on the belt's history, so let's take a look at how the final 10 World Championship reigns stack up against one another.

10 10. Big Show (First Reign) 

Big Show defeated Mark Henry in a chairs match at the 2011 TLC pay-per-view to become the new World Heavyweight Champion. However, Henry attacked Big Show following the defeat, and Daniel Bryan took advantage of the situation by cashing in his Money in the Bank contract.

Bryan scored the easy pinfall over Big Show to become the new World Heavyweight Champion, meaning the latter's reign lasted no more than a couple of minutes. Nothing to see here.

9 9. John Cena

Cena may be tied with Ric Flair for the most World Championship reigns with 16, but his final run with the the World Heavyweight title in 2013 wasn't anything spectacular nor memorable.

He defeated Alberto Del Rio at the 2013 Hell in a Cell pay-per-view to win the title. Following a couple of successful defenses, Cena faced Randy Orton at the TLC pay-per-view, with the winner becoming the unified "WWE World Heavyweight Champion."

Cena lost the match to Orton, thus ending his World Heavyweight Championship reign at just 49 days. With that, the Viper held the notion as the final champion in the title belt's history.

8 8. Dolph Ziggler

Alberto Del Rio was the World Heavyweight Champion entering the Apr. 8, 2013 episode of Monday Night Raw. But it all came to an end when Dolph Ziggler used his Money in the Bank contract cash-in to become the new champion.

Ziggler unfortunately suffered a concussion and couldn't wrestle for a large portion of his title reign. He defended it against Del Rio at the 2013 Payback pay-per-view, but Del Rio emerged victorious to win back the Championship. With that, Ziggler's reign ended at 69 days.

7 7. Big Show (Second Reign)

Less than a year after Daniel Bryan destroyed his World Heavyweight Championship dreams, Big Show was able to redeem himself at the 2012 Hell in a Cell pay-per-view by defeating Sheamus. It marked the second World Heavyweight Championship of his storied career.

Big Show was able to defend the title against The Celtic Warrior at the TLC pay-per-view several weeks later. Other title defenses ended via disqualification rulings, but Big Show finally dropped it it to Del Rio on the Jan. 8, 2013 episode of SmackDown.

Big Show's run as champion was over at 72 days, and he would never win the title again.

6 6. Alberto Del Rio (First Reign)

As noted above, Alberto Del Rio ended Big Show's second run with the title. And the former's second go as World Heavyweight Champion went a lot smoother than the Big Show's previous reign.

Del Rio successfully retained his title by defeating Big Show at Royal Rumble and Elimination Chamber. He also conquered Jack Swagger at WrestleMania 29 to keep the title reign going.

However, Del Rio's run ended when Ziggler cashed in his Money in the Bank contract on the Apr. 8 episode of Raw, ending his reign at 89 days.

5 5. Mark Henry

The World's Strongest Man clashed with Randy Orton for the title belt at the 2011 Night of Champions pay-per-view, and Henry was able to come out on top to capture the World Heavyweight Championship for the first time in his career.

Henry would keep the title for 91 days, but he finally lost it to Big Show at the aforementioned 2011 TLC pay-per-view. Of course, Big Show's reign ended right then and there once Bryan cashed in his MITB contract.

4 4. Daniel Bryan

With a successful cash-in, Daniel Bryan won the World Heavyweight Championship for the first time in his illustrious career. This set the stage for Bryan to pull off an unexpected but epic heel turn, and he continued his program with the Big Show over the next couple of months.

Bryan was able to remain champion following an Elimination Chamber match at the 2012 pay-per-view. However, Bryan's superb 104-day run as the champion ended when Sheamus defeated him at WrestleMania XXVIII.

3 3. Alberto Del Rio (Second Reign)

Del Rio's original run as the World Heavyweight Championship wasn't terrible by any means, but his second one certainly went much better than the first.

As noted earlier, Del Rio defeated Dolph Ziggler at the 2013 Payback pay-per-view to regain the World title. Del Rio had numerous successful title defenses, against the likes of Ziggler, Christian (at SummerSlam) and Rob Van Dam.

However, Del Rio's incredible 133-day run came to an end when John Cena took him down at the 2013 Hell in a Cell pay-per-view. Del Rio never regained the World Heavyweight Championship.

2 2. Randy Orton

Randy Orton became the final World Heavyweight Champion in WWE history when he defeated Cena at the 2013 TLC PPV. The WWE and World title belts were unified that night, making Orton the "WWE World Heavyweight Champion."

Orton had an extremely successful run as the champion, holding it for 161 days. This included successful title defenses at Royal Rumble against John Cena and at the Elimination Chamber.

The Viper thendefended his title against Batista and Bryan in a triple threat match at WrestleMania XXX. Bryan became the new champion after getting Batista to submit to his Yes Lock. This ended Orton's run as the first WWE World Heavyweight Champion at 161 days.

1 1. Sheamus

Sheamus defeated Daniel Bryan at WrestleMania XXVIII (in just 18 seconds) to win the World Heavyweight Championship. Few could have expected it at the time, but Sheamus would embark on one of the longest reigns in the championship's history.

The Celtic Warrior was able to retain the title at several pay-per-view events against top-tier opponents like Bryan, Chris Jericho (at Over the Limit) and Alberto Del Rio (SummerSlam as well as Night of Champions).

Sheamus' spectacular 210-day reign would conclude when Big Show took him down at the 2012 Hell in a Cell pay-per-view. But Sheamus knew not to cry because it was over, but to smile because it simply happened. What a title run it was.
