Mike Tyson was known for his ferocious and intimidating boxing style, as well as his controversial behavior inside and outside the ring.

He was trained by Cus D'Amato, who became his legal guardian after Tyson's mother passed away.

Tyson's early career was marked by a series of quick knockouts, earning him the reputation of a fearsome puncher.

In 1992, Tyson was convicted of rape and sentenced to six years in prison; he was released on parole after three years.

After his release, Tyson returned to boxing and regained the WBA and WBC titles, but his career declined following the losses to Holyfield and Lewis.

Beyond boxing, Tyson has appeared in various films and television shows, authored books, and performed a one-man show about his life.
