Phaz-Ing

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.

Trivia
