Initially serving as manager for fellow list member Kimo Leopoldo, Joe Son made his MMA debut in 1994 at UFC 4. After losing to Keith Hackney, Son would move into the film industry, landing a role in the smash-hit comedy Austin Powers: International Man of Mystery in 1997.
Son would return to combat sports in 2002, after signing with PRIDE Fighting Championships in Japan. He would lose both fights in which he took part in the Japanese organisation, and also lose a further bout against Joe Moreira in a contest that was officially recorded as him having submitted due to terror.
It was only years after Son's utter failure of a combat sports career that the true nature of the South Korean's exploits outside the cage were revealed. In 2008 DNA evidence linked him to the rape and torture of a woman in 1990. Son was also later convicted of killing his cellmate and will now spend the rest of his life in prison.
Son's heinous crimes will see him spend the rest of his life in prison, and although it does nothing to repent for his villainous deeds, seeing Keith Hackney battering his ballsack into oblivion at UFC 4 now feels completely karmic.
