Tremy holds the title of Sagitta Silver Knight within Sanctuary's hierarchy. His pivotal narrative action involves firing the god-killer arrow directly into Athena's heart. This act ignites the central conflict of the Battle for Sanctuary storyline and imposes a strict twelve-hour time limit on Athena's survival. Following the arrow strike, Tremy engages the Bronze Knights in combat but suffers defeat. During this confrontation, he divulges the critical information that only the Grand Master possesses the power to remove the arrow, establishing the necessity for the protagonists' perilous journey through the Twelve Temples. His actions and subsequent defeat define his role as an antagonist aligned with the corrupt Sanctuary leadership under the Grand Master. Information regarding Tremy's origins, training, motivations beyond his mission, or character development across the Saint Seiya franchise is unavailable. His appearances occur solely within the Battle for Sanctuary narrative arc of the 3DCG animated series. The character does not appear in the original 1986 anime, subsequent OVA series like Saint Seiya: The Hades Chapter, any animated films, or spin-off manga such as Saint Seiya: Rerise of Poseidon or Saint Mariya.
