Leviathan Doors are a special type of Door unique to Metroid Prime 3: Corruption found in Leviathans, the first being found located in Landing Site Delta. They generally have very little security, with the Guardian of the Leviathan protecting the Phazon Core. The door behind the energy shield is made of four bone plates, presumably part of the Leviathan Seed, and are asymmetrical in appearance. They are similar to Phaaze Doors.
