Generator B is the final exploreable room in Base Sector Zero on Norion. It appears in Metroid Prime 3: Corruption.

Description

During the Space Pirate invasion on Norion, Rundas manages to bring Generator B back online for Samus Aran, who reactivates Generator A and Generator C, in order to activate the Defense Cannon and destroy the Leviathan headed directly for the planet.

Afterwards, when Samus explores the area, the room is overrun with spent Phazon from the invasion. Having ignored the warnings of the Federation Marine standing near the entrance, Samus continues on to the area she has not yet explored. She finds smashed glass containers along the corridors leading to the main generator, hinting that something was kept near the generator, but escaped or was released during the Pirate attack. Inside the room, a Morph Ball tunnel is covered in indestructible brown growths covered in Phazon spikes and spines, which glow brightly as soon as Samus enters, spawning a Metroid Hatcher from the ground.

Its defeat causes the growths to crack and explode, exposing the generator control center, and allowing Samus to move through the tunnel and collect an Energy Cell. Exploration of this room is entirely optional, as only five of the nine Energy Cells in the game are mandatory to obtain the Leviathan Command Codes on the G.F.S. Valhalla, and thus complete the game.
