7 Wrestlers who have been World Champion in both WWE and TNA 

#2 AJ Styles

The Face that Runs the Place

Styles might arguably be the greatest wrestler of his generation. And when he won the WWE Championship at Backlash in 2016, it was the culmination of lifelong a journey for wrestling greatness. When Styles does end up hanging up his wrestling boots, he will surely go down as one of the all-time greats.

Styles was known as 'Mr. TNA' back when he was with the company and he was truly the heart and soul of the brand. TNA has surely not been the same since he left in 2013. During his time there, he won their World Championship on five occasions and in all honesty, the company misused most of the time. He was never the 'face of the company' that he should have been.

After leaving TNA, he would go on to wrestle for Ring of Honor and NJPW, before shocking the world and joining the WWE. His debut at the 2016 Royal Rumble is surely one of the greatest moments in the history of the event.

Styles' fans would have been justified in fearing that he would have much success in the company but they have been proved completely wrong by Styles. He has won the WWE Championship on two occasions and has currently held on to the title for over 300 days in his second reign.
