Eclipse Ophiuchus (オフィウクス Ofiukusu), "The Snake Charmer" (蛇遣い Hebizukai), is the Eclipse form of the Celestial Spirit Ophiuchus whose Gate is referred to as the "13th Gate". Her key is currently owned by Yukino Agria, but the contract was severed, causing Ophiuchus, along with the rest of the Zodiac, to rebel. However, what Ophiuchus truly desires is to grant the rogue Celestial Spirit King even more power by stealing the life force of the twelve Eclipse Zodiac Spirits.
