Galactic Federation mothership

The Galactic Federation mothership is a Galactic Federation-operated spaceship seen at the beginning of Metroid: Other M. It features a quarantine room, empty training room and meeting room. While these locations are not revealed as part of a mothership in the game, its status was confirmed in issue 59 of Official Nintendo Magazine on page 76.

Samus Aran is seen being rehabilitated in the quarantine room after her ordeal on Zebes. She awakens to the voice of the Head Quarantine Officer and enters the training room to test her skills at the officer's direction. After this is done, Samus enters the meeting room to report the destruction of the Metroids, and Zebes. The meeting room is guarded by a Retinal 10 Scan. After this, she departs the mothership. Unbeknownst to her, fragments of the baby were removed from her Varia Suit during her surgery, and then used by the ringleaders aboard the BOTTLE SHIP to clone Metroids.
