Big match John has had a ton of memorable feuds over the years. He has faced the best of the best and not many have been able to get one over on the The Champ. Everyone from Shawn Michaels to Triple H and CM Punk to Roman Reigns have all gone one-on-one with the Leader of Cenation. Hall of Fame calibre stars such as Undertaker and The Rock have tussled with WWE's resident Superman.
There are some men who haven't taken a swing at the 16-time Champion yet, though. Some of WWE's biggest names have never had a feud with Cena. Whether it is because they are new to the roster or because it just hasn't been on the cards, he just hasn't had it out with some of these men. To be clear, for the purpose of this list, having a match doesn't qualify as a full feud. Let's get to the count down.
#5 Shinsuke Nakamura
Cena vs Nakamura did take place on an episode of SmackDown Live in 2017. The match was to crown a number one contender for Jinder Mahal's WWE Championship. John lost to The Artist, who is now on his way to a WrestleMania main event after winning the Royal Rumble. He could step up and be Nakamura's very first challenger after Nakamura claims the gold.
Shinsuke and Cena could be old school vs new school. WWE gave us a glimpse of this back in the Royal Rumble, when Cena, Orton and Mysterio faced off with Balor, Nakamura and Reigns. Nakamura could strengthen his claim as the new 'face that runs the place' while Cena can try and prove he can still hang with the new era.
The two could have multiple show stealing performances and the leader of Cenation could bring a lot of passion to this feud. Nakamura claiming that he doesn't view Cena as a real threat could make The Champ attempt to step his game up even more.
#4 Bobby Roode
The Glorious One vs the face that runs the place. Expect some really intense promos from these two guys in the feud. Roode can begin the feud as a face, but eventually after losing to Cena, he completely snaps. Him working as a heel against Cena would be gold. These two have a mic presence that most others just don't, and you hear it through the promos they cut.
Neither man is a slouch in the ring either and can have some truly entertaining matches together. With both men growing in age at this point in their careers, it is best for them to get this feud going as soon as possible. This program can send the Glorious One straight from the middle of the card into the main event scene.
#3 Samoa Joe
John Cena and Samoa Joe have a well documented past as they started out at the same place together. They later took extremely different career paths that eventually led them here and finally, these two can lock it up inside a WWE ring. Cena being a free agent allows him the flexibility to go between the brands and make it possible for him to gear up for a major feud with Joe. To spice things up, Joe can be the Intercontinental Champion coming into this feud.
These two portray completely opposite characters and seeing them square off on the mic or in the ring would be interesting to observe, with Joe brutalising Cena and forcing him to dig deep and find his fire to fight back against the Samoan submission machine.
When the dust settles and these two are finished waging war on each other, Cena can raise the Intercontinental Championship high.
#2 Braun Strowman
These two men are so over that seeing them clash just makes sense. It will be a true clash of the titans when these two collide. Strowman dispatched of Cena pretty easily in the Elimination Chamber and that could be incorporated into the feud, playing up how much of an underdog Cena would be against the Monster among Men. Having wrestlers and announcers giving Cena no shot to slay the monster could put him in a place we haven't seen. He himself may not believe he can beat Strowman.
Strowman could absolutely destroy Cena and that could force him to start thinking of retirement. During a leave of absence for Cena, Strowman becomes Universal Champion. This would motivate John to come back to face Srowman again; win, lose, or draw he would give the monster his best shot.
A desperate Cena trying to scratch and claw his way past the most unstoppable force WWE has ever seen, sounds like a great feud. Passion is Cena's strong suit and seeing him on the brink of retirement may just give us the peak of his performance.
#1 Finn Balor
A final passing of the torch is always required before retirement and if Balor's run in NXT is any indication of his potential as the face of a brand, he is the perfect fit as the final torch-bearer. The Demon King can roll into this feud as a heel who has used the numbers game to get ahead.
He and the Balor Club can beat down the 16-time World Champion and tell him it is time for him to pull the curtain and take his final bow. The feud can see the first ever Universal Champion constantly go over Cena with assistance from Gallows and Anderson.
Eventually, Balor runs into AJ Styles, another bullet club alumni, who tells him not to go down this path. Styles tells him that if he wants the torch, he has to take it from Cena by himself, with no outside help. This leads to Balor dropping his Club and eventually going at Cena alone. Cena gets bested by the Demon on the 'grandest stage of them all' and rides off into the sunset, having faced all of WWE's top guys.
