Rousimar Palhares — The Leg-Lock Maniac Who Wouldn’t Let Go

Palhares was a submission specialist—but not the friendly kind. The Brazilian fighter had a habit of holding onto submissions long after his opponents tapped, leaving a trail of broken bodies and torn ligaments. In his final UFC bout, Mike Pierce later said Palhares tried “robbing some of my quality of life”. He was released from the UFC for repeatedly refusing to let go of submissions. He fought like there were no rules—and he made sure everyone around him paid the price.
