Aku Aku is a good-hearted and peaceful being, but at the same time, he knows when to take important matters (like saving the world) seriously. He is kind and has helped Crash, Coco, and Crunch throughout many of the games, and acted as a father to them. He is also obedient to the rules of his superiors "The Ancients", mysterious beings who strangely have never been seen. He also seems to understand what Crash is saying, often translating for him. Like his brother, he seems to dislike not having a body, but not to the same extent.
