|This article is about a/an villain headquarters in Power Rangers in Space, the last installment in the Zordon Era.|
The Dark Fortress was the space-traveling lair of Astronema and her crew. It was armed with Satellasers that made Astronema's Monsters grow. It also had a large complement of Quantrons and Velocifighters on board. It was mostly seen hidden in a pocket dimension that alternated between a purple background and a blue background due to Sentai Footage. The Dark Fortress was capable of not only space travel, but atmospheric travel as well.
Astronema's private scheming room was next to the main control room; it perhaps also doubled as her bedroom. In one part of the Dark Fortress, Astronema had a pet monster known as Skruddly, which often tortured Elgar when he annoyed her.
Astronema held command over the Dark Fortress throughout most of Power Rangers in Space, though Darkonda briefly held command in "Dark Specter's Revenge". The Dark Fortress was last seen on Earth, after it was commandeered by Andros in "Countdown to Destruction".
