Boxing star Naoya Inoue, known as "The Monster," has been devouring opponents for over 12 years and is now a four-weight world champion. Regarded by many fans and experts as the finest pound-for-pound fighter on the planet, Japan's warrior-hero has utilized state-of-the-art firepower to score 26 knockouts in 29 straight wins.
While Inoue has appeared in world title fights in the U.S. and the U.K. before, this explosive 32-year-old boxer-puncher made his bones in Japan and is already a millionaire several times over. His sixth-round knockout of Mexico's Luis Nery at Tokyo Dome in May last year reportedly earned him a career-high 1 billion yen (roughly $7 million at current rates).
