Yu-Gi-Oh! episode 145: "A New Evil - Part 1"
Grerimo, known in Japan as Grimo, is a member of Doma, appearing only in the Waking the Dragons story arc. His name is never spoken in the English anime, but it was confirmed by Seto Kaiba's voice actor Eric Stuart that his official dub name is "Grerimo".
Grerimo is Rafael's subordinate. He defeats Rex Raptor and Weevil Underwood and captures their souls. After Rafael, Valon and Alister steal the Egyptian Gods from Yugi Muto, they give "Obelisk the Tormentor" to Grerimo, who proceeds to challenge Yugi using it and "The Seal of Orichalcos".
Yugi manages to defeat him, though Grerimo's soul is absorbed by the Seal. It is unknown what officially became of Grerimo's soul at the end of the arc though it was most likely released as every other soul captured on-screen by the Seal was set free.

Grerimo uses a Warrior Deck. His strategy focuses on swarming the field with his warriors, utilizing the effects of Magic Cards that Summon Tokens. Combined with the ability of "The Seal of Orichalcos" that allows the player to use his Magic & Trap Card Zones as Monster Card Zones and "The A. Forces", he can Summon many powerful monsters very quickly. This strategy works well with "Obelisk the Tormentor", giving him enough monsters to Tribute for both its Summon and effect.
