John Cena is about a month away from celebrating his 10-year WWE Anniversary.
During that time, Cena has been pitted up against some of the WWE's finest.
However, there are only a select few that helped mold Cena into the star he is today.
Like him or not, Cena will go down in history as one of the biggest stars, if not the biggest, in WWE's history.
Cena has been the face of the company since it transitioned from the "Ruthless Aggression" Era to the PG Era and managed to transcend his character to fit the WWE's needs.
Ultimately, without these feuds Cena may not have been able to shine and show the WWE that he is here to stay.
