- Wrecked Ship
When Phantoon came in control of the Wrecked Ship, he possessed souls of the ancient Chozo who perished there. Multiple victims have been massed together into the Coven, which writhes and howls. Tormented by Phantoon, their ghosts were transformed into evil spirits that haunt the depths of the ship, seeking out the living to enact their malice. Trapped between dimensions, Coven will appear in this world, then disappear and move to a new location. When Samus defeated Phantoon, these lost souls were finally released.
Coven will mysteriously appear, then disappear and float towards Samus’ position. While they reappear, you have a short period of time to get away, or you will take damage. They have a large amount of HP, but can be easily destroyed with Power Bombs. Conserve your Super Missiles for the fight with Phantoon.
Coven was mistranslated as "Covern" in the US Manual from the Japanese "Koben" (コーベン). A coven is an assembly of witches, especially a group of 13.
The Metroid: Other M concept art for Phantoon confirmed that the Wrecked Ship is of Chozo origin, even though the Coven looks like it is made of human faces.
