Somebody Know's how to do a Chaos Chao in Sonic Adventure Dx?
Please i waiting your ask.

Actually, I can help.

What you need to do, is have a chao that has reincarnated twice (I suggest leaving your game on at night). Then, feed it EXACTLY one of each animal, and let it evolve. It takes a lot of time, but it isn't hard.

ok, well!, but doesn´t work if my chao reincarnate 3 times?,
do you know how to make step by step the "spear chao"?
Like what animals give him and others options.

Im not sure what the spear chao is, but ya, as long as your chao has reincarnated twice or more its fine.

This chao:

Do you know?
So, later of gave him the animals, one by species, i don´t give him a dark fruit or hero fruit?, or i give him only chao fruit?

Hmmm....it just looks like a normal colored dark...power? swimming? chao. As for chaos chao, it is actually better to let your chao reincarnate MANY times, training it in all of its stats until it has S in everything, that way when it becomes a chaos chao, it can reach full potential instead of being stuck at low levels.
