In his WWE career, AJ Styles has won the WWE Championship, three times the United States Championship and once the Intercontinental Championship, making him the only wrestler in history to have held at least one world title in WWE, NWA, NJPW and TNA.
His second reign from WWE Champion, which lasted 371 days (from November 7, 2017, to November 13 2018), is the eighth longest in the history of the title and the longest in the history of the SmackDown roster (exceeding the previous record of 280 days by John "Bradshaw" Layfield).
Styles is considered one of the best wrestlers of all time, so much so that he was in the first place of the PWI 500 in 2010 and was named by the same magazine as the best wrestler of the decade 2010-2020. In an interview with Sports Illustrated, AJ Styles spoke about his Boneyard match with The Undertaker at Wrestlemania 36.
AJ Styles on The Undertaker
“I found out I was going to be working The Undertaker right before the Saudi show [in February]. I was like, ‘Finally, I get an opportunity to learn from a guy like The Undertaker.’ I was super excited about it.
I was so jealous of guys that got to work him. For me, to be able to learn from the best, it was a blessing. There were definitely some crazy moments. Undertaker had to get stitches after he busted his arm open. That just added to the match, to be honest with you.
Just being there and doing that particular match was awesome. And I don’t know if everyone knows how long it actually took. We started around eight o’clock, and we didn’t get finished ‘til about 4:30 in the morning.
It was basically a movie, so we needed to get cameras in the right spot and walk through some stuff that was going to happen. I have a lot more respect for actors after working on those fight scenes" - AJ Styles explained on WrestleMania 36.
“I didn’t know I was going to be up all night. Nobody really knew how long this was going to take, so how do you prepare for something you don’t know? But it all worked out. It was difficult to stay up that late, but we pumped each other before the fight scenes.
Undertaker and myself, we did our fight scenes in one take. That’s all it took. But at one point, Undertaker had his scene with the minions, so we were waiting for our spot to come up. The waiting, that part was long, but it was still good. The way it all turned out was unbelievable" - he added.
