Triple H has led the tributes from the world of wrestling to Big Van Vader, who died on Wednesday aged 63.
Vader, whose real name was Leon White, was a three-time WCW champion and also enjoyed strong runs in the then-WWF and Japan, where he left a groundbreaking legacy as a big wrestler who performed athletic moves.
"Leon White entertained (and intimidated) audiences all over the world with his size, strength, and agility," said Triple H. "Saddened to hear of his passing and our thoughts are with his family at this time."
Ric Flair, who had one of the greatest Starrcade main event matches against Vader in 1993, said: "Sorry To Hear About The Loss Of Another Great! Rest In Peace My Friend!"
Ken Shamrock made his WWF debut against Vader, and wrote: "Vader was one of the 1st big men to show that big didn't mean limited skills, speed or agility. He was a beast! I had my 1st WWF match with him & was very pleased with his toughness & endurance. My prayers go out to his family & friends."
Michael Hayes said: "So saddened to hear of the passing of Vader. Leon was one of a kind, whether on the grid iron or in the ring. I am proud to have been in the ring with him and lived to tell about it. Deepest sympathies to his family, friends and fans."
Current Raw superstar Bobby Roode wrote on Twitter: "Very sad to hear about the passing of Vader.Had the opportunity to share some time with him a couple years ago before coming to WWE. Happy I had the chance to meet him. Condolences to his family."
Matt Hardy commented on Vader's legacy, saying: "Thoughts & prayers go out to the family & friends of Leon White after his passing. He made an ENORMOUS impact on our industry. Godspeed, Big Van Vader."
Booker T wrote: "Sad to hear about the passing of Vader. He was one of the all time greats. My prayers go out to his family, may he rest in peace."
