Phaz-Ing are amorphous creatures composed of Phazon. They tend to appear only in areas afflicted by Phazon Corruption.
Phaz-Ing possess limited shapeshifting abilities, but they are primarily used for self-defense. They mostly stay in the form of an amorphous mass of liquid Phazon, which is able to move across virtually any surface. When threatened, they will take a solid form and fling a blast of Phazon. They are most vulnerable in this state, as they unable to move until they shift back into liquid form.
- Phaz-Ing resemble the Inglets from Metroid Prime 2: Echoes. In fact, the appearance and behavior of the two creatures is virtually identical.
- It is possible that the Phaz-Ing may be connected to the Ing, though there has been no official confirmation.
