AJ Styles
AJ Styles arrived at WWE two years ago, but he has already achieved much more than other wrestlers in the company. He proved this at Fastlane 2018, where he made history.
The 'Phenomenal' surpassed the 100-day mark as champion. This was enough to make him the 11th wrestler to hold the title for that long.
But the most impressive thing is that he is the third WWE World Champion to achieve this in all of his reigns. The only others who were able to accomplish this were Randy Savage and Bruno Sammartino.
AJ Styles' first reign lasted 140 days, while the second one is currently at 125 days and counting. The goal is to hold the title even after WrestleMania 34.
On April 8th, he will face Shinsuke Nakamura. This will be the third mega event for AJ Styles, but the first one where he enters as champion.
