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

#6 Mick Foley

Mick Foley has been at the top of both companies.

Mick Foley's runs as WWE and TNA World Heavyweight Champion are complete contrasts of each other. While he was one of the best wrestlers in the world during his WWE days, he had been retired for almost a decade when he decided to join TNA.

TNA cannot be blamed for not giving up the opportunity of having one of wrestling's biggest legends on their program. But by this point, he was just a mere shell of his Mankind/Cactus Jack days and had no business in the ring. But that did not stop TNA from trying to gain some attention by making him their World Champion.

But the plan fell flat and the company took the title off Foley just 63 days later. Thankfully, they did not actually go through with their absurd idea of having the World Championship defended just once a year like the Super Bowl.
