Rousimar Palhares is a Brazilian mixed martial artist. A professional competitor since 2006, he has competed for the Ultimate Fighting Championship (UFC), World Series of Fighting (WSOF), Fight Nights Global (FNG), and Konfrontacja Sztuk Walki (KSW). His nickname Toquinho (Portuguese pronunciation: [toˈkĩɲu]) Portuguese for "little tree stump" comes from his short, stocky, heavily muscled build and the low success rate his opponents have had in grappling him down to the canvas. Palhares is primarily known for his powerful ground game. Of his 16 submission victories 12 have come from leg locks. He is also known for his refusal to release submission holds when either the opposing fighter has signaled submission or the referee has called a stop to the bout, causing him to be fired by the UFC and WSOF. Palhares however is also known for his aura of invincibility as his only defeats were disqualifications. His dirty fighting style, however, can also be seen as a source of inspiration and something new in the sport; for example, the Diaz Brothers who openly have a kind of friendship with Palhares and Nate Diaz citing him as his top 3 inspirations for fighting along with Mike Tyson and Earnie Shavers.
