you either pet it with an evil character or abuse it with a good character
No, it doesn't matter!
Where the chao is raised doesn't matter; it will take the alignment of whoever raises it the most. A good indicator is the wings; if they are dark, your chao is getting more evil, and vice-versa.
YOU COLD-HEATED EVIL PERSON! you gon on to the chao transporter holding a chao and click "goodbye" HE/SHE WILL BE SENT INTO A COLD DARK FOREST AND HE/SHE SHALL BE GONE FOREVER! SERIOUSLY PEOPLE YOU COLD HEARTLESS EVIL DEVIL!YOUR SICK!YOU DISCUST ME!
Either get a two tone grey chao and make him a shadow chao or a two tone blue or sky blue chao and make either of them a shadow chao or a two tone black chao.
Treat it good with both EVIL and hero characters
it takes a little while for chao to get older but you have to care for it and after a while(depending on which character you use hero or evil)then the chao will go to the stage of chao death.
No you can not make a chao age faster
you can't really make a gold chao unless it's ancestors were gold chao.
You can only make hero and dark chao in SAB2. Also Sonic chao are neutral so if you give your chao a lot of run animals you will get a Sonic chao.
You can't make a Chaos Chao look like Sonic, but you can make a regular Chao look like him.
Yes
It just the way the game goes.
