Tourian

Tourian is the main headquarters of the Space Pirates' fortress on Zebes, and the residing place of the Mother Brain. It is almost completely artificial, with structures largely made of metal materials, and corridors formed through metal pipework. Artificial lifeforms such as Rinkas, Zebetites and automated turrets provide defense and security for the Mother Brain. Surprisingly, while this is indeed the main HQ of the Pirates, there where none to be seen in the NES Metroid, but this is later retconned in Metroid: Zero Mission, where a cutscene shows a Metroid outbreak has occured, killing all Pirate personnel; several dried bodies can be seen throughout Tourian. In Super Metroid, Metroids are once again the main creatures to battle leading up the path to Mother Brain, but whether they broke loose again or were intentionnaly released is never made clear. Also, Space Pirates seem to populate the Tourian sections found behind Mother Brain's command post. Still, the multiplicated Metroids are the main obstacles that make the path to Mother Brain's chamber a very difficult journey.

In the rebuilt Tourian, several native creatures of Zebes reside within a somewhat organic zone of the area, along with the Infant Metroid that Samus brought with her from her mission on SR388. Exposed scaffolding and circuit boards are prominent features in this location, indicating that construction is an ongoing process.

Access

 * Metroid: Defeat Kraid and Ridley to gain access to the Morph Ball bridge, at the end of which is an elevator leading to Tourian.
 * Metroid: Zero Mission: Defeat Kraid and Ridley just as in the original, but this version depicts their statues as gateways. The mouths of these statues will open in the circumstances of actual defeat, giving you a pathway to the main Tourian elevator.
 * Super Metroid: Defeat Kraid, Phantoon, Draygon, and Ridley. A Gold Statue depicts these four beings, and will sink to the bottom of its cave once all four are defeated.

Trivia

 * It is stated by Samus in Metroid (manga) that Tourian is the place where the Chozo and Mother Brain make decisions that influence the Federation.


 * In Metroid: Zero Mission, if the player returns to Tourian after beating Mother Brain, there is a blue-green, highly corrosive liquid that has replaced the lava in Mother Brain's chamber. It is unknown what the substance is or how it got there, but it is severely dangerous to step into, even with the protection of the Gravity Suit. In most probability, it is some sort of waste from the now inactive power systems in the destroyed area. But this same substance is present on board Sector 1 of the BSL Space Station, in the Tourian-like area where you can find Ridley-X.
