Ivan – Died in 2017

Popularly known as the Russian Bear, Ivan Koloff was a fierce Canadian wrestler who was best known for his appearances in the World Wide Wrestling Federation. The greatest achievement he had in his career was when he won the WWF World Heavyweight Championship. After he decided to leave the ring, he was just useful if someone wanted to organize a WWE-themed wedding. Unfortunately, Ivan took his last breath back in 2017 and passed away at the age of 74. The cause of his death was said to be liver cancer.
