Final Omega's chamber

The final Omega's chamber is a room in Metroid II: Return of Samus and Metroid: Samus Returns.

Description
The Chozo Tower is located in Area 7 of SR388, and is explored during Samus Aran's mission to exterminate the Metroids. This chamber contains one of the three remaining Omega Metroids; depending on the order Samus chooses to exterminate them, this room may be home to the last Omega that she faces before progressing onward to Area 8.

In Return of Samus, the final Omega's chamber is a oval-shaped rocky cave with a small lake of the unidentified liquid seen throughout the latter half of Phase 8. This gives it a unique layout that is not seen in the other two Omega Metroids' rooms. A Metroid Husk sits on the left bank of the lake in front of the room's entrance, revealing that the Omega Metroid resides in this cave.

In Samus Returns, the final Omega's chamber is guarded by a Gigadora. Along with the rest of Area 7, it is redesigned as an artificial room in the abandoned Chozo laboratory, with metallic architecture, sparking wires, and a malfunctioning hologram displaying the Morph Ball. Since the Omega Metroid took up residence here, the chamber is now covered with large organic structures formed from Metroid webs. This final Omega Metroid is a unique specimen, with the same color scheme as the evolved forms of Alpha and Gamma Metroids.

In Samus Returns, after the Omega Metroid is killed, Samus can return to the chamber to find it guarded by Gunzoos and an Autoad. These robots are commonly seen throughout the Area 7 laboratory as part of the Chozo security system.

Connecting rooms
In both games, the final Omega's chamber connects (via a Gigadora-covered door in Samus Returns) to a corridor; in Return of Samus, the corridor has bubble-like structures over a pit of liquid and spikes, while in Samus Returns it is heavily expanded and now features an observatory.
