#8: Sonny Liston
Liston radiated intimidation and toughness. Built like a tank, he bulldozed opponents with bone-shattering punches and an unflinching demeanor. He endured a brutal upbringing, prison, and hostility from the public yet remained fearless in the ring. Liston’s willingness to walk through punishment and impose his will made him a feared force.

In 1962, Liston challenged Floyd Patterson for the heavyweight title. Amid heavy criticism and public doubt, he steamrolled Patterson, knocking him out in the first round. That dominant performance under pressure showcased Liston’s toughness — shrugging off outside hostility and proving he could conquer the sport’s biggest stage.
