You can get a Shadow Chao by making your Chao into a Dark/Running/Running type.
Pet it and feed it with the Dark Characters - Shadow, Eggman, or Rouge to turn it Dark.
The most important part is to give it Green Chaos Drives or animals that raise its Running stat. When it evolves, it should be a Dark/Running type. (This would be its firstevolution!).
After your Chao evolves, keep raising its Running. If you notice it will start to look like a Shadow Chao after awhile, then it will be a Dark/Running/Running type.
Hope this helps! :]

first choose shadow the hedgehog then get allot of green chaos drives it will evolve but you have to give it more chaos drives(green)then the green on it will turn red and you will have a shadow chao.
There is sonic, tails, knuckles, amy, rouge, eggman, shadow, chaos zero, tikal, dark chao, normal chao, metal sonic. So that would be 12 characters.

This is how to get a Shadow chao in Sonic Adventure 2 step by step. 1. Hatch a chao egg with Shadow, :Note: the egg shouldn't be from the Black Market at the Kindergarten: 2. Give the chao green chaos drives as Shadow. 3. Pet the chao as Shadow and cuddle with it as Shadow often. 4 Once the speed level is 10 or 15, raise the stamina to level 5, 10, or 15. 5. Wait for the chao to evolve and hopefully, you get a Shadow chao! (I did!)
Sonic Advance 1, 2 and 3 (Gameboy Advance) have chao gardens which are small and not very great, but Sonic Adventure (Dreamcast), Sonic Adventure DX (GameCube), Sonic Adventure 2 (Dreamcast), Sonic Adventure 2 Battle (GameCube) all have chao gardens where you can do the most things and raise your chao the best and most effective. Sonic Adventure 2 Battle is the most convinient and shows you all you need to know about a chao, and it's a really good game to raise them in by using animals (and Chaos Drives) as a means of training them. Sonic Advance 1 and 2 can connect up to Sonic Adventure 2 Battle and Sonic Adventure DX via a Gameboy to GameCube link cable and you can exchange chao with.
