How do you get character chaos in sonic adventure 2 battle

Here's a way 2 make some character chaos: Sonic Chao: Get a regular chao and give it green drives w/sonic until it evolves.make sure it's neutral. Shadow Chao: Do the same thing as the sonic chao but with shadow.make sure it's dark. NiGHTS Chao: Make a regular chao a Neutral Fly/Fly type. Super Sonic Chao: Same as Sonic Chao but with a yellow,shiny yellow(i think is the best color for this)or gold. Hyper Shadow Chao:same as Shadow Chao but with a white,shiny white(might be the best),or some kind of white two toned.
