|Anime debut||Yu-Gi-Oh! episode 145: "A New Evil - Part 1"|
Gurimo is a member of Doma, appearing only in the Waking the Dragons story arc of the second anime series.
Gurimo is a bearded man with dark hair, a high forehead and a widow's peak, in addition to a monocle over his left eye. He dresses in a dark sleeveless hooded robe over green-grey clothing.
Gurimo Duels strategically, and appears decently skilled as he was able to defeat both Weevil and Rex at the same time. He shows complete loyalty to the organization to which he belongs. He also appears to like a challenging/skilled opponents, as he called his Duel against Yugi "refreshing" compared to past opponents.
Gurimo's name is drawn from The Three Musketeers' character Grimaud, a servant to Athos, Count de la Fère, who Rafael's name is drawn from.
Gurimo is Rafael's subordinate. In the first episode of the Doma arc, he defeats Rex Raptor and Weevil Underwood and captures their souls. Later, after Rafael, Valon, and Alister steal the Egyptian God Cards from Yugi Muto, they give "Obelisk the Tormentor" to Gurimo, who proceeds to challenge Yugi using it and "The Seal of Orichalcos". By infecting it with the Seal's power, Gurimo even manages to control "Obelisk" without the fatal side effects which usually occur when those deemed "unworthy" attempt to Summon the Egyptian Gods.
Yugi defeats "Obelisk" with "Brave Attack", and later won the Duel with "Diffusion Wave-Motion" and "Dark Magician Girl". Due to losing, Gurimo had his soul absorbed by the Orichalcos.
Gurimo runs a Warrior Deck, focused on a swarm strategy. His monsters' otherwise mediocre ATK are increased by both "The Seal of Orichalcos" and "The A. Forces". His Deck and its swarm ability is also able to take advantage of the fact that "The Seal of Orichalcos" allows him to control up to 10 monsters at once, as he places his more vulnerable monsters in the back row to prevent them from being attacked while his more defensive monsters are summoned to the front row. This strategy also can work well with "Obelisk the Tormentor", as it gives him enough monsters to Tribute for both its Summon and effect. However this strategy can also lead to his undoing, as if multiple monsters are destroyed at once, he takes even more damage, as Yugi proved.
- In the English dubbed anime, Gurimo's name is never spoken out loud, instead mostly being referred to as "the old man" by Alister and Valon. Eric Stuart, Seto Kaiba's voice actor in the dub, once stated that his dubbed name was "Grerimo" , but this was retconned by multiple more recent sources, including Konami's blog, which retain a romanization of his original Japanese name.
