Chaos was initially good. Sega said his origins was that he was once one of the many chao but mutated into a water creature by the power of the emeralds. Due to the environment around the altar it was suitable habitat for chao. Chaos befriended Tikal and they were buddies.

But when her father Pachacamac tried to take the emeralds by force and harmed his own daughter violently, this caused chaos to be enraged and turn evil. Perfect Chaos was formed so tikal sacrificed herself to be sealed into the Master Emerald along with Chaos. While they were together for millenia, chaos rage did not pass.

When Super Sonic fought Perfect Chaos, Super Sonic managed to neutralise the darkness in Chaos heart making him nice again.

I don't quite understand the intelligence of Chaos. He can be reasoned with but it took Super Sonic knock some sense into Chaos and let go of his 4000 year old tantrum. Maybe he has the IQ to that of a chao or something.
