Gurimo

Grerimo, known in Japan as Grimo, is a member of Doma, appearing only the "Waking the Dragons" story arc. His name is never spoken in the English anime; it has been confirmed by Seto Kaiba's voice actor Eric Stuart that his official dub name is "Grerimo".

Biography
Grerimo is Rafael's subordinate in the Japanese anime. He defeats Rex and Weevil and captures their souls. He later challenges Yugi, using Obelisk the Tormentor and The Seal of Orichalcos against him. Yugi manages to defeat him, though, and 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.

Deck
Grerimo uses a Warrior Deck. His strategy focuses on swarming the field with his warriors, taking advantage of The Seal of Orichalcos's ability that allows the player to summon additional monsters to the Field, and then uses The A. Forces to give his monsters a high ATK boost.
