Tia Halibel is an Arrancar who formerly held the position of Tres Espada in Sosuke Aizen's army. Her aspect of death is sacrifice. After Aizen's fall, she became the de facto ruler of Hueco Mundo, but later suffered defeat at the hands of Yhwach and was captured by the Wandenreich. Halibel is a cold and calculating fighter, but behind her outward detachment lies a deep concern for those close to her. She refuses to gain power at the cost of others' lives, preferring to fight in a group rather than alone. Her loyalty to her faction, the Tres Bestias, is boundless, and she is ready to avenge them. In battle she uses water, controlling it through her resurrección Tiburón. Despite the cruelty of the world of the Hollows, Halibel has preserved her own principles and sense of justice.
