im trying to make a chaos chao, and as i read through some of the articles from game faq, one of the article says that to make a chaos chao, the chao has to remain neutral until the final evolution. But if i have a chao that turned into a hero and it reborned as a neutral chao with white color, will that make any difference? Is it necessary for the chao to stay neutral all the way?
No. A chao can have any alignment during any of its lives and still become a Chaos chao.
