Chao (disambiguation)
Chao are small, cute creatures that appear in Sonic Adventure and Sonic Adventure 2. Depending on how you raise them, they will grow into an Light Chao, Dark Chao, or Normal/Neutral Chao. There is also the Chaos Chao, which is far more powerful then the normal Chao and never dies. The Chaos Chao also come in three different forms: Light Chao (neutral), Devil Chao, and Angel Chao. The only way to make a Chao a Chaos Chao is to have it reincarnated twice, have one of each animal, and have no chaos drives. There are 75 forms in all. Depending how you raise them and what chaos drives/animals will depend on what it grows into. A notable Chao is Cream the Rabbit's Chao: Cheese, which happens to be a Neutral Chao.
In Super Smash Bros. Brawl
A Chao appears as a Sticker and a trophy in the game.
