Vader aka Big Van Vader -- who wrestled in WWE, WCW and all over the world -- has passed away at the age of 63-years-old ... this according to his family.

One of Vader's children tweeted from his account saying, "It is with a heavy heart to inform everyone that my father, Leon White, passed away on Monday night (6/18/18) at approximately 7:25pm."

Adding, "Around a month ago my father was diagnosed with a severe case of Pneumonia. He fought extremely hard and clinically was making progress. Unfortunately, on Monday night his heart had enough and it was his time."

As you may recall, Vader underwent open-heart surgery in March. Vader spoke in-depth with Bill Apter about the surgery before it happened and called himself a “walking time bomb” due to having ten clogged blood vessels.
