The Galactic Imperial Army Zone are the main antagonist faction of Chikyuu Sentai Fiveman. They are an army of aliens that travel across the Universe attacking planets so as to complete a ritual which will award their leader immortality.
The Imperial Army is led by Galactic Empress Meadow, a mysterious entity who appears as the head of a woman in the sky to give orders to her subordinates. Zone's forces operate from their flagship, Vulgyre (in reality, the de-facto leader of Zone), which is capable of dispensing smaller ships called Vulgols.
Zone utilize the galactic credit Dolyen as their currency, which has an exchange rate of 100 Yen or 0.66 U.S.D. They also celebrate the holiday "Topsy Turvy Day", where Zone's Commanders take orders from their nominal subordinates.
