|Anime debut||Yu-Gi-Oh! GX episode 65: "No Pain, No Game"|
Mr. Shroud, known in Japan as Monkey Saruyama「モンキー猿山」(Monkī), is a shady duelist manager who introduces Zane Truesdale to underground dueling in order to redeem himself after his chain of failures in the Pro League. Shroud uses electronic devices to pressure duelists in underground dueling. Shroud is pleased when Zane realizes the pointlessness of respecting opponents. However, when Shroud reminds Zane that he was the one who got him where he was, Zane throws him out of his car, firing him.
In the English dub, Shroud has a Southern accent, reminiscent of a carny.
Shroud's Japanese name is a combination of the English word "monkey" and the Japanese word "saru", which means monkey in English.
