The Mother Ship was recognizable for its purple, enormous and bulky appearance, coupled with relatively short, sturdy wings. Along with areas built into the ruins of Chozodia, a docking bay was constructed containing Space Pirate Fighters. When ships entered or left the Mother Ship, a door in the front would open, resembling a mouth or beak. Scan images aboard the Frigate Orpheon in Metroid Prime feature the ship as being shaped similarly to the Mother Ship, implying that they are of the same model. The ship replaced the Space Pirate Flagship depicted in the Metroid Manga.
