John Cena has more Extreme Rules(ER) experience than almost anyone on the WWE roster.Cena has been around since theERpredecessor —One Night Stand— which gave birth to the now-infamous "If Cena Wins We Riot" sign that has been copied and parodied ever since.He's been involved in everything from a standard Extreme Rules Match to a Triple Threat Steel Cage Match, and has faced a variety of opponents from The Great Khali and Ryback to Brock Lesnar and Batista.

It was recently announced that John Cena plans toreturn from injury atMonday Night RAW on Memorial Day. But John Cena has been known to heal quicker than doctors anticipate, and the WWE creatives loves to throw the WWE Universe for a swerve.

Will John Cena be atWWE Extreme Rules 2016? It's highly unlikely. But as Vince has always liked to say: anything can happen in the WWE.

What follows is the first part ina series of Extreme RulesRésumé articles in which we take a look at a current or former WWE Superstar's history at Extreme Rulesand what their past experiences might tell us about that same (or a similar) competitor atWWE Extreme Rules 2016 on May 22.

Extreme Rulesrecord

Counting his 3One Night Stand appearances, John Cena is 6-3-1 at WWE's annual hardcore event.

He had a five-year undefeated streak between 2007 and 2011.

Through the years, he's seen such stipulations as Extreme Rules (2), Last Man Standing (2), Falls Count Anywhere, First Blood, Submission, Steel Cage, Triple Threat Steel Cage and even a Russian Chain Match.

Of his 10 matches, 6 of them were for WWE gold.

On five occasions, Cena competed atExtreme Rules/One Night Standfor the WWE Championship. Four times, he left with the belt. Last year, Cena successfully defended the WWE United States Championship at ER.

Main event matches

Like most PPVs of the last decade, John Cena has main evented exactly half of theONS/ER shows in which he's competed.

The most notable of hisERmain events was his 2012 bout with Brock Lesnar, marking the return of the Beast Incarnate to WWE competition.

His match with Lesnar was the last time Cena headlinedER. Had it not been for his injury, would Cena be competing for the WWE World Heavyweight Championship in two weeks?

Worthy competition

Not everyone that John Cena has faced atExtreme Rules is headed for the WWE Hall of Fame. Beating The Great Khali or Ryback isn't exactly something to write home about, and John Morrison won't go down as a WWE Legend. Guys like Rusev and Bray Wyatt still have a few things to prove.

But the rest of his opponents make a pretty impressive list of former WWE Champions: The Miz, Rob Van Dam, JBL, Big Show, Batista and Brock Lesnar.

Most extreme moment(s)

While Cena may be the biggest star in the company, he's not exactly known for being "extreme." The bloodiest match he's ever had atERwas against Brock Lesnar in 2012. The most memorable match, however, may have been against Rob Van Dam atOne Night Stand in 2006. RVD successfully cashed in Money In The Bank in front of the ECW hometown crowd.

It was also atER 2011 that John Cena announced to the entire WWE Universe that Osama Bin Laden had been killed by Seal Team 6.

Predictions forWWE Extreme Rules 2016

While it would certainly be a huge shock for the WWE Universe, there's no reason to expect that John Cena will be atWWE Extreme Rules. But this year, as the WWE tries to make Roman Reigns the next John Cena, could Cena's history give us an idea as to what Reigns can expect?

Of the five times John Cena walked intoERwith a WWE title, he left with the title four times. Of the five time John Cena headlinedER,he won three matches. I think the safe bet is that Roman Reigns defeats AJ Styles atWWE Extreme Rules 2016, as the WWE builds towards a feud for the rebirth ofWar Games.

WWE Extreme Rules 2016airs live on the WWE Network on May 22.
