This is AJ Styles' first title defense and it might be his last as he takes on two of the best superstars right now.

AJ "The Phenomenal One" Styles is one of the most decorative wrestlers of all time. He wrestled all over the world from small indie promotions to the big leagues. He is best known as a master of offensive innovation. He has the ability to adapt and adjust in any kind of match up against anybody.

However, AJ will face not only one, but two of the best in ring performers right now. First in line is the Lunatic Fringe, Dean Ambrose. Ambrose is one of the charismatic wrestlers right now and he has a rugged style of wrestling. Ambrose held the WWE World Champion until Backlash when the face that runs the place, AJ Styles defeat him in a controversial win.

Ambrose has not forgotten what happened when he and AJ met for the title. Ambrose is one of those guys who is willing to give his body to reach his ultimate goal. But sometimes, him being the "lunatic fringe" gets himself in trouble and being outsmarted by his opponents.

And then there is John Cena, the Champ, the man who took WWE on his shoulders for about a decade. We all know what Cena is capable of and we know his vision is clear in tying "The Nature Boy" Ric Flair's record of being the only two wrestlers recognized as 16-time world heavyweight champion.

So who has the edge on this triple threat match? It depends on how you look at it and it depends on who are you rooting for. If you are going for Ambrose, then you have the right to choose him since he wants retribution and this is his rematch when he lost the title. If you want Cena to win, then I get your point. You want Cena to tie Ric Flair's record and we know Cena will do that, sooner or later.

But don't count out the reigning, defending WWE World Champion. As many superstars have stated, AJ "The Phenomenal One" Styles is unpredictable. His ring brilliance is on top of the chain right now. He is a once in a lifetime performer and he shines brightest on the biggest stage.

Best way to end it? My pick would be AJ Styles retaining the WWE World Champion. We've seen the ratings, Styles can carry Smackdown live and I want to see more of heel Styles. As for the other two, a lot of storylines can be produced after No Mercy. AJ Styles VS John Cena II is a great story on their rivaled history or AJ Styles vs Dean Ambrose: Redemption.

Let us check some of the highlights and the stories building against these three bitter rivals. Each of them were able to execute their finishers, who you got? AA? Dirty Deeds? Or Styles' Clash?
