Air of Dark Aether

Dark Atmosphere is an obstacle in Metroid Prime 2: Echoes that appears only in Dark Aether.

Role
The toxic atmosphere of Dark Aether is the primary danger in the dark dimension and will begin to burn any being that is not protected from it or is not a denizen from Dark Aether.

When Samus steps into the atmosphere unprotected, her suit will begin to corrode and make a fizzing noise, and will take damage rapidly, at 5 units of damage per second. While in the toxic air, the screen will periodically flash in a faint yellow and the Threat Assessment meter will immediately reach its highest level unless Samus seeks shelter in Light Beacons that are placed all throughout Dark Aether. The Dark Suit once acquired will protect Samus from the atmosphere, reducing the damage rate to only 1 unit per second. Once the Light Suit is acquired, however, Samus will be completely immune to the burning air, and the Threat Assessment meter will no longer trigger.
