Uranus

Uranus stands among the three Ancient Weapons that date back to the Void Century, the other two being Poseidon and Pluton. Its existence first reached readers through a conversation between Nico Robin and King Neptune, where she noted that three such weapons each carry the name of a god.

As with its two counterparts, Uranus is understood to be a weapon of catastrophic potential, capable of dominating the world or laying waste to it depending on whose hands grip it. Beyond that broad warning, no concrete account of its capabilities has been given.

No wielder of Uranus has ever been identified. Everything about the weapon, its deeds during the Void Century, its design, its location, and its ultimate fate, remains a mystery. Vegapunk and Ivankov suspect that an Ancient Weapon fueled by the Mother Flame destroyed the Lulusia Kingdom, and since Uranus is the only one of the three still unaccounted for, speculation points its way, though nothing has been verified. Its name traces to Uranus, the primordial sky deity of Greek myth and father of the Titans.
