The WWE icon, who memorably battled Hulk Hogan at WrestleMania 2, died on March 4. He was 61.
The athlete's death was confirmed by longtime friend David Herro on Facebook, and by the WWE.
"Today we lost a Legend and a man I consider family. Rest in Peace Chris," Herro wrote. "We love you. Thank you for believing in me. #KingKongBundy."
Bundy, whose real name was Christopher Alan Pallies, entered the WWE in the early '80s, and later enjoyed a brief acting career, appearing in two episodes of the sitcom Married... With Children as well as the 1988 Richard Pryor comedy Moving.
