My friend and i were playing sonic AD Battle 2 last night and when he was in his chao garden, one of his chao's started to evolve (covered by the egg like shell) only when he came out, he was neither hero or evil. He then took it to the doctor and under its status it said instead of child, Normal type. and instead of being hero or dark it was Neutral. The ball above his head is still a normal ball, the one that he was born with. Is this a sign that he will evolve into a Chaos (Kaos) Chao? Please tell me it is because if it is then i will finaly be able to witness the evolution of a chaos chao. This was a dream i have had since i got Sonic 2 and i really want one. does anyone know the answer to this?
