Neutral Chaos Evolution
The Light Chao
First of all, you must reincarnate your Chao at least twice. When this is done, you must then give the Chao ONE of EVERY animal (Yes, all 21 animals - NO CHAOS DRIVES).
Note: When making a Light Chao, make sure it stays neutral for evolution by using a mixture of Hero and Dark characters to care for it.
When it evolves it will be a Light Chao!
