5 things John Cena has never accomplished in his WWE career

John Cena. Some fans love him, some fans loathe him, but one thing fans can't deny is that he has had an extraordinary career. Debuting on SmackDown in 2002, the Massachusetts native quickly rose through the ranks of WWE, winning his first championship at WrestleMania 20.

Winning his first world title a year later, Cena has become a 16-time World Champion, a record tied with Ric Flair. Even out of the ring Cena has thrived, becoming a poster boy for WWE and recently focussing on a growing acting career.

But despite all this success, there are some things Cena hasn't done. For one reason of another, even one of wrestling's biggest heroes hasn't been able to do it all Here are five things John Cena has never accomplished throughout his WWE career.

#5: Pinning the boss

John Cena is yet to pin the Chairman of WWE, or make him tap out.

John Cena may have been the name and face of the WWE for the better part of a decade, but that doesn't mean he always saw eye-to-eye with the company's chairman Mr McMahon.

In fact, in his two separate matches where Big Match John has faced the boss of all of WWE, he hasn't fared too well. In their first match, Cena did beat McMahon, though didn't look like a winner, as he only won via Disqualification after being assaulted by McMahon's son-in-law, Triple H.

Meeting again in 2010, McMahon pinned the 16-time World Champion on RAW, though again had a bit of help. After it was clear Cena would demolish him, McMahon quickly made the bout a No-Disqualification handicap affair, and with Cena outnumbered, even the WWE's Superman was no match for the chairman of the board.

#4: Intercontinental Championship

The prestigious title is just one of the few championships that have alluded Cena.

Gold and John Cena go together like Mick Foley and thumbtacks. Over his many years in WWE, Cena has held an astounding 16 World Championships, a reign only tied by the legendary Ric Flair.

Not only that, but Cena is also a former United States Champion and Tag Champion, but it is the prestigious Intercontinental Championship that has alluded him. To be fair, when Cena moved to RAW which showcased the title in 2005, he was already a main eventer, bringing the WWE Championship with him.

The IC title being absent from his trophy case also means that Cena lacks the Grand Slam, something that must be in the back of Cena's mind. Nothing is ever set in stone in WWE, so we'd be mighty careful if we were Intercontinental Champion Finn Balor right now...

#3: A successful Money in the Bank cash-in

Cena won the 2012 RAW MITB Ladder match, but lost when he cashed-in.

At the Money in the Bank 2012 pay per view, John Cena made history (again), when he became the latest man to be hailed as Mr. Money in the Bank. But a few days later, Cena would make history in the worst possible way, becoming the first man to cash-in the contract and lose.

Meeting WWE Champion CM Punk on RAW 1,000 in July, Cena hoped to add to his litany of world championships, at the expense of the Best in the World. That was until the Big Show arrived, costing Cena the match and the title due to a disqualification.

Since then, a small handful of Superstars have failed upon cashing-in, but Cena's name will always live on as the first to do so, an accolade nobody wants.

#2: King of the Ring

The last King of the Ring was Wade Barrett in 2015.

Though the last few winners of the King of the Ring tournament amounted to very little, there was a time when the crown was a huge deal. A simple elimination tournament, the contest would see who was the best on the roster, and saw plenty of careers rise to prominence thanks to the crown.

After all, the list of former Kings is a true who's who of wrestling, including Bret Hart, Triple H, Brock Lesnar, Kurt Angle, and 'Stone Cold' Steve Austin. An elite list, it is shocking that Cena's name isn't on it.

To be fair, the last year the King of the Ring had a pay per view (2002), was the same year John debuted on SmackDown, and by the next time a tournament was held (2006), Cena had already established himself as the face of WWE.

#1: Outlast The Undertaker's WrestleMania match streak

The Deadman has a total 26 WrestleMania matches compared to Cena's 15 matches.

Though The Undertaker's WrestleMania winning streak may be a thing of the past thanks to Brock Lesnar, the Deadman does boast another record at the event. Appearing at an incredible 26 WrestleManias, the Deadman holds the record for the most matches at the showcase of the immortals.

Unfortunately for Cena, this will take some serious catching up to, as since his debut at Mania 20, John has competed at 15 WrestleManias, with his last match being last year against the Phenom himself.

For Cena to topple this mighty record, he would need for The Undertaker to retire now, and to wrestle at WrestleMania each year, every year until WrestleMania 47 in 2031. With Cena now being more of a part-time Superstar, we don't see this record being broken anytime soon.
