Syrus Truesdale, known as Shō Marufuji(丸藤翔Marufuji Shō) in the original Japanese language version, is a fictional character in the Yu-Gi-Oh! GX anime and manga series. In the English version, Syrus is voiced by Wayne Grayson, while Masami Suzuki takes the role in the Japanese version. A decent duelist, though hindered by a great deal of self-doubt, Syrus' journey toward strengthening himself provides sharp contrast to protagonist Jaden Yuki's active determination.
