| Chaos Chao are immortal versions of the Chao. I hate that they stick with only one design(or 3, 1 for Dark, Neutral, and Hero), so that means they won't get a custom design as per how you would normally do it. I don't believe their colors can be slightly changed either.
Anyway, Chaos Chao, I believe, aren't even appearable in Sonic Advance(nor sure about Advance 2, though), as your Chao just looks like a basic Chao via the design of Black, Light Blue, and White(Dark, Neutral, and Hero respectively). I haven't played Sonic Advance 1 in a long time, so I forget how the Hero Chao's colors worked. |
