Is there anything else than a hero chao and a devil chao?

Yes, there is the four Neutral Chao. Hardest chao for beginners. You must keep a chao normal, so it won't be too Hero chao or too Dark chao. So raise it with both hero and dark characters. The chao will turn into a weird color. IF it is not white or not dark color. Also while doing that give them lots of drives. Animals will ruin the looks of these chao. Don't pet it to much, if you do, switch characters to make it even. You any Chaos Drives, There is four different types of these chao, swim, power, run, fly, each one very different. Remember, try to keep the chao at the blue color! Until it evolves!

NOTE: This prosses takes as long as a normal chao to evolve, take your time. If your chao is hero or dark. Then it was too hero or too dark. These chao is HARD to get, be careful!! Don't feed it to much, let the chao feed itself.

Also there is a Angel Chaos Chao (My Favorate), Neutarl Chaos Chao and Devil Chaos Chao. You can find out how to get these further in the questions and answers section.
