The Imperial Fortress is the mobile capital of the Imperial Alliance. It is the Imperial Alliance's homeworld of Gelma modified into a roving space fortress. It is where both the Imperial Master and the Imperial Council reside.
History[]
Following Commander Makara's failure to destroy X-Bomber and capture the F-01, the Imperial Master decided to capture Lamia himself and directed the Imperial Fortress to head towards Earth's solar system.
Once the Imperial Fortress had arrived in Earth's solar system, the Imperial Alliance began a massive assault on Earth with the goal of crippling the Earth Defense Forces and killing Lamia before she could awaken as the F-01. During the battle, the crew of the X-Bomber attempted to attack the Imperial Fortress in the Dai-X, but the Imperial Master shot them down with a beam fired from the Imperial Fortress.
Although the Imperial Alliance was able to destroy half the Earth Defense Forces, they were unable to stop Lamia from awakening as the F-01, leading her to head to the Imperial Fortress to confront the Imperial Master and put an end to the fighting. The fight between the two saw the Imperial Fortress being destroyed and the Imperial Master disappearing along with it.
