From Metroid Wiki
Dark Water is a toxic liquid prevalent on Dark Aether, first referred to by A-Voq. Both the Varia Suit and Dark Suit are susceptible to its damaging effects. Only the Light Suit offers protection sufficient to completely negate its effects.
- "The waters of Dark Aether are foul and venomous. Avoid them if you can." —A-Voq (Metroid Prime 2: Echoes)
- "Samus's Notes:
The suit is fully resistant to the effects of Dark Aether.
The suit is also invulnerable to the effects of dark water. You can move through it without being impeded.
The Light Suit is able to access the Luminoth energy transport system. You can ride these beams of energy between regions on Aether." —Samus's Notes (Metroid Prime 2: Echoes)
- "Morphology: Dark Shredder
Darkling-possessed flying plantform.
Durable plantform gains strength from Ing possession. Immune to dark water.
The hardy Shredder is a favorite possession target for Ing that dwell near dark water. Dark Shredders can lurk in the venomous liquid indefinitely, patiently waiting for prey. When agitated, it will emerge and begin to fly toward its foe. They are very resilient, but can be eliminated with concentrated weapons fire." —Metroid Prime 2: Echoes Logbook "Dark Shredder" (Metroid Prime 2: Echoes)
- "Morphology: Chykka
Flying insectoid Guardian.
This light creature can be stunned, especially by dark energy. While stunned, look for weak spots to target.
The Chykka has rapidly aged to its adult form. It will attack by firing high-powered bursts of dark water at rapid speed. If frustrated, it will attempt to dive and ram you. Most of the Chykka's body is vulnerable to weapons fire, but scans indicate that such fire will only stun it. When stunned, however, four weak spots will appear. These spots are vulnerable to attack; target them to damage the enemy." —Metroid Prime 2: Echoes Logbook "Chykka" (Metroid Prime 2: Echoes)
