"Neo-Ridley's room" is a metallic room within Sector 1 (SRX) on the Biologic Space Laboratories research station. It appears in Metroid Fusion. This is where Neo-Ridley is fought and defeated.


Neo-Ridley's room is a large metallic vertical shaped room with a red hue at the end of the Tourian-like area of Sector 1 (SRX). The room's purpose is unknown. The floor and walls are metallic and separated into multiple panels, similar to the electronic junkyard found in Sector 5 (ARC). The door featured at the top right of the room locks upon Samus's first entry of the room. To exit, Samus must Space Jump.

It resembles the room in which the original Ridley is fought in his Lair in Super Metroid.


Upon falling into the room Samus finds the corpse of the Ridley clone, replicated after the copy she had seen in Sub-Zero Containment shattered, with an X Parasite escaping. The corpse appears to be inanimate at first before its eyes glow red and it morphs into Neo-Ridley. Samus battles and defeats the X Parasite mimic of her nemesis, and absorbs its Core-X, regaining her Screw Attack ability. After this, she can leave the room.

Connecting rooms[]

The room is entered from a corridor filled with Beta Acid and Rippers, guarded by a Gadora.



  • In an earlier prototype of Metroid Fusion, Neo-Ridleys' room has a more bluish coloration (see gallery below).
