Mike Tyson
Tyson was and still is one of the most intimidating men on the planet. The former heavyweight champion demolished opponents during his heyday. But he also lived on the edge and is a polarizing figure. One of his wildest suspensions came after he bit off a large chunk of longtime rival Evander Holyfield’s ear.

The Nevada Athletic Commission banned him for 15 months because it was gloriously illegal. Meanwhile, Tyson spent a lot more time outside of the ring because of a rape conviction. He also admitted that he used a fake penis to manipulate drug tests because he often fought while high (via CBC).
