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.
There is sonic, tails, knuckles, amy, rouge, eggman, shadow, chaos zero, tikal, dark chao, normal chao, metal sonic. So that would be 12 characters.
