The Chykka was a massive dragonfly-like creature that lived in the Dark Torvus Bog on Dark Aether. It is fought in Metroid Prime 2: Echoes as the Guardian of Dark Torvus Temple.

The creature was born as a larva, and soon cocooned itself to turn into the Chykka Adult. If the Chykka Adult is exposed to the poisonous water of Dark Aether, it will transform into the Dark Chykka, which can hatch mutated Chyklings.

Defeating it earns Samus the Dark Visor.
