9. Evangelous Goussis
A former middleweight champion in kickboxing, Evangelous Goussis was also briefly a professional boxer. The Australian has become infamous for his criminal record which is definitely one of the craziest on this list. Goussis was heavily involved in the Ozzie gangland scene and served time in the 90s for drug trafficking and attempted murder.
In 2008, he’d be charged with shooting two Melbourne gangster in the head. He was sentenced to life in prison with a chance of parole after 33 years. What a crazy guy.
