Chaos 0

Chaos 0 is a Projector+ exclusive morph in Sonic Projector: RP.

Chaos 0 is from Sonic Adventure and its subsequent re-release Sonic Adventure DX: Director's Cut.

Background
Chaos is an immortal, god-like creature composed entirely of concentrated energy. It is the guardian god of the Chao and their friends, and it has the ability to change form for each Chaos Emerald it receives.

The original guardian of the Chaos Emeralds and the Master Emerald, Chaos watched over a Chao colony in ancient times until an attack from the Knuckles Clan led to it being consumed by a fury that threatened to destroy the world. However, it was sealed in the Master Emerald before it could succeed.

After millennia of imprisonment, it was released by Dr. Eggman in a plot to conquer the world. Despite initial cooperation however, Chaos turned on Eggman and tried to destroy the world, but was calmed by Sonic and departed for places unknown.

Since then, Chaos only appears in times of great crisis.
