Thunder (character)

Thunder, known in Japan as Ikazuchimaru (雷丸) is Frost's tag duel partner against Syrus and Tyranno. 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 "Ikazuchi" portion of his name in the Japanese version is derived from the word "ikazuchi" (雷), meaning "lightning."

Deck
Thunder plays a Thunder deck, supported by tag duel-exclusive cards. His tactics are more upfront than his partner's in that he utilizes cards such as Rampage Condenser and Lightning Talisman to inflict damage directly, rather than through battle.
