Area 8, previously known as Phase 9 in Nintendo Power, is the ninth and final area explored on SR388 in Metroid II: Return of Samus and its remake, Metroid: Samus Returns.


In Return of Samus, Phase 9 begins with narrow tunnels winding upward to a massive open cavern. These tunnels have pools of an unidentified liquid. If Samus steps in certain pools, she will fall through fake ground and be dragged down to the bottom of the tunnel network. The massive cavern is home to several Septoggs, which can assist Samus traveling to the top. There, she will find the apparent ruins of a Chozo settlement, containing a Big Energy Ball and Missile Battery; a destroyed Chozo Statue that once held an Ice Beam; and the entrance to the Metroid nest. A secret exit in the Queen Metroid's lair will return Samus to the destroyed Chozo Statue, allowing her to recharge her energy and missiles before returning to the fight.

In Samus Returns, Area 8 is an odd ecosystem containing green webbing; pulsating fungi-like vegetation; a yellow liquid flowing from odd formations in the ceiling; large spikes; and other substances found exclusively in rooms occupied by Metroids. This suggests that Metroids warp their environment to resemble their preferred habitat.

Despite this area being the main hive of the Metroids, most of it seems to be synthetic and artificial. Glass tubes and temple-like structures can be seen throughout Area 8, strikingly similar to those from the Chozo laboratory in Area 7. Many guardian robots such as Autracks and Gunzoos can also be found in this area in the remake. This might be heavily hinting on the existing connection between the Chozo and their creations, the Metroids.

Once Samus enters the Metroid nest in Morph Ball mode, she passes underneath a single Metroid Egg in a cavern, and then her Metroid Detector suddenly reacts to the presence of Larva Metroids. In both games, a tense and unsettling music track plays as Samus enters the Metroid nest, which changes once she detects the Larva Metroids and proceeds to hunt them down. In Return of Samus, the previous song continues playing at a higher pitch; in Samus Returns, a sped-up techno remix of the Tourian theme can be heard instead.

After exterminating these Larva Metroids and the Queen Metroid itself, Samus discovers the Metroid Egg and witnesses it hatching, giving birth to an Infant Metroid known as the baby. As it imprints on her as its mother, Samus chooses to take it with her back to the Surface, through a tunnel that gradually shifts from Area 8's aesthetics to the Surface's terrain. As it orbits around her, the baby carves out otherwise-indestructible crystals blocking the way. In Return of Samus, the tunnel is completely empty; in Samus Returns, there are many weaker enemies and item expansions along the way. This sets in motion the events of Super Metroid and subsequent sequels.

Samus ReturnsEdit


  • In Metroid II, the Ice Beam is the only item here because it is required to defeat the Metroids in the area. In the room containing it, the Chozo Statue supposed to hold it is broken, with the head being nearby. The Item Sphere containing the beam is right behind it. It is possible that the Metroids, perhaps the Queen herself, were aware of the item being held by the statue and knowing the danger it posed for them, attempted to destroy it.
    • As the Ice Beam is a standalone beam option acquired once in Area 1, this Chozo Statue does not exist in Metroid: Samus Returns.
  • Area 8 is the most depicted area of SR388 in other media and games, as it is featured in flashbacks of the baby hatching.
