Mike Tyson was a beast in the ring in his heyday. Heck, he was a beast even before his heyday.

In this unearthed video, a 15-year-old Tyson absolutely demolishes a poor soul named Joe Cortez during the 1981 Junior Olympic Championship.

The bout lasted nine seconds and shows Tyson's legendary hard, forceful punches that later became a trademark.

Tyson, of course, went on to become the heavyweight champion of the world, which, if you told people would happen after this took place would probably not come as a surprise. This, by the way, was one of two Junior Olympic titles he won.
