The Light Brigade
The Light Brigade, known in Japan as the Four Monarchs (四帝, Yon Tei), is a group of assassin duelists in Sarina's service. All four Members decks are centered around a "Monarch". In addition, each member of the Light Brigade possesses some sort of element-based power. T-bone and Blaze are shown to travel through earth and fire, respectively, and the four seem to be responsible for using the Duel Spirits of the Monarch cards to create a barrier.
The Light Brigade is introduced as Duel Academy students go on a field trip to Domino City. There, Frost and Thunder duel and kidnap Tyranno Hassleberry and Syrus Truesdale. T-Bone later duels Jaden Yuki and loses.
