Maurício Miguel Pereira, commonly known as Maurício "Behring" or "Maurição da Hunter" (Maurição of Hunter / Hunter's Maurição) was one of the top jiu jitsu figures of the late 1990's and early 2000's decades, be it a promoter/sponsor (through his Hunter Fightwear brand), as an athlete (who conquered medals at the Brazilian Nationals and Pan American Championships) and as an instructor having helped the development of athletes such as Fabrício Werdum, Márcio Corleta, Mário Reis, Rodrigo Munduruca and many more. His tragic death in 2006 shone light onto a highly controversial aspect of Brazilian law which deems a trained martial artist a "cold weapon", allowing the use of deadly force with a firearm in claims of self defence against such an individual. He was also often mentioned as "Maurição da Hunter", which literally translates to (Hunter's Maurício) due to his well known jiu jitsu brand "Hunter".
