Segata Sanshiro
One of the manliest characters on the gaming world, on the WHOLE fucking world, Segata Sanshiro isn't nearly as famous as Chuck Norris, because unlike him, Segata is a real badass, not an attention whore.
Originally created by SEGA to market the fucktastic Sega Saturn on Japan, where its sales were much higher than Playstation sales for some time. Srsly.
