No. 7: Mike Tyson

Once dubbed "The Baddest Man on the Planet," Michael Gerard Tyson took the boxing world by storm in 1986 when, at 20 years old, he defeated Trevor Berbick to become the youngest man to win a world heavyweight title.

But a year after losing his title belt in 1990 to 42-to-1 underdog Buster Douglas, Tyson was arrested on a rape charge. He was convicted in 1992 and served three years in prison.

After his release from prison in 1995, Tyson returned to the ring, eventually regaining a portion of the heavyweight title before losing to Evander Holyfield in 1996. In their much-anticipated rematch a year later, Tyson shocked viewers by biting off a piece of Holyfield's ear, earning him a disqualification.

Tyson, now 42 and retired from professional boxing, earned a reported $300 million throughout his career.
