Ｑ：Hi!! I'm from Portugal and I love Sonic Games. My question is, do Chao evolve like the Chao of Sonic Adventure? Or they only turn into dark and"hero" Chaos? Ａ：Boa tarde! Thank you for your question. Your Chao will change into "Hero Chao", "Dark Chao" or "Neutral Chao" depending on how you raise your Chao. Then, Chao will grow up into 5 different types just like in the previous Sonic Adventure. "Neutral Chao" will grow up exactly the same as the one in Sonic Adventure. If you want to raise a "Neutral Chao", you need to think which player character is better to raise your Chao. It all depends on how you raise your Chao.
