The Last Time Is Now. It's the name given to the tournament in which 16 wrestling giants have been competing to be the one opponent in John Cena's final fight before retirement.
And that final fight is now - Saturday night - in Washington DC, bringing the curtain down on an illustrious career that has seen the American become one of wrestling's biggest and most bankable stars.
In the 8,570 days since his debut, Cena has clinched 17 world titles and coined the iconic You Can't See Me catchphrase - but the 48-year-old's impact goes far beyond that.
If you were to pose the question who is John Cena?, depending on who you ask, the answers might vary from legendary WWE (World Wrestling Entertainment) superstar, to successful film actor, while some will say he's Mr Make-A-Wish.
Since his 2002 debut, there's been an evolution in his own wrestling character - transitioning from ruthless aggression rookie, to a Doctor of Thuganomics rapper, and eventually a heroic character known for a Never Give Up attitude.
Despite criticism from some fans of his in-ring ability, with occasional chants of you can't wrestle through the years, there's no doubt that he's an exceptional wrestling talent, says Brandon Thurston, editor and owner of wrestling website, Wrestlenomics.
Cena's journey has also included significant charitable contributions, most notably through the Make-A-Wish Foundation, where he holds the Guinness World Record for the number of wishes granted.
Explaining his reasoning at the time, he told of the physical toll wrestling had taken on his body as he nears his retirement. With his final match approaching against Gunther, there's no time limit, ensuring fans will witness a memorable conclusion to Cena's wrestling story.
