Chaos Chao

 are rare and hard-to-get Chao. It has a different form depending on whether it is Hero, Dark, or Neutral. They are called Chaos Chao because they have eyes like the Sonic Character, Chaos.

Getting a Chaos Chao
Getting a Chaos Chao is hard, but rewarding. First, the Chao must undergo two evolutions. You have to be kind to it so that it will reincarnate and evolve twice again. Then, if you are nice to it again, it will reincarnate again. If you can manage to get through these steps, then evolve it twice for the final time and it will be a Chaos Chao.

Neutral Chaos Chao
The Neutral Chaos Chao, often called the Light Chao, has the largest resemblance to Chaos. It has arms like Chaos, and the eyes that look most like them. Also, Chaos has two "spikes" drooping from the back or its head. The Light Chao has them from the sides. Instead of a round ball, the Light Chao has a ball of shining light at the tip of its point, hence "Light Chao."

Hero Chaos Chao
The Hero Chaos Chao is often called the Angel Chao. Instead of two bumps for its point, has two floppy ear-like things that hang down. Its halo is also see-through. Its eyes are blue. Its chest becomes an orange shade instead of yellow, the the tips of its hands and feet as well as its ear-like things have raspberry tips. It looks like an Angel, hence "Angel Chao."

Dark Chaos Chao
The Dark Chaos Chao, often called the Devil Chao, is the Chaos Chao that looks the least like Chaos. Its crest turns yellow as well as its eyes. It gains devil horns, and hanging spikes from its head; the tips of the hanging ones look like they are lava. This color also goes for the tip of the hands. Its feet turn purple. It resembles a devil, hence the name "Devil Chao."
