HistoryĪncient Chao had different features to the lovable creatures known in modern times, but they weren't all that different. They have been around in the Sonic world since at least early tribes of guardian echidnas, if not since the creation of the Chaos Emeralds, or closely after or before. They are known for their ability to mutate if cared for correctly. A Chao (pronounced 'Tchah-oh') is a small, usually harmless creature with a notoriously short lifespan and an ability to rebirth itself if it was treated correctly and not abused.
