Frost

Kourimaru (氷丸 Kōrimaru) / Frost - Thunder's tag duel partner against Syrus and Tyranno. Unlike Thunder, he valued victory above all else, and was not above eliminating his partner from the duel. He was sealed in a mirror by Sarina when she no longer had any use for him, but was freed alongside the other Light Brigade duelists after Jaden and Aster defeated her. The "Kouri" portion of his name in the Japanese version is derived from the word "kōri" (氷), meaning "ice." In the English version, he has a Hispanic accent.

[edit] Card list Frost plays an Ice deck, supported by tag duel-exclusive cards. His tactics are less upfront than his partner's in that he utilizes cards such as Mobius Castle and Mobius Glacier to weaken his opponents' monsters, then destroy them through the attacks of Mobius the Frost Monarch.
