Aku Aku

Aku Aku (Japanese: アクアク) is a witch doctor whose spirit now lives in a wooden mask who guides Crash, his sister Coco, and their friends as they defeat the forces of evil. He has made appearances in every Crash Bandicoot game, although one of them is just a cameo. In the platforming Crash games, from the original up until Crash of the Titans, if 3 masks are found, Crash becomes invincible for a limited amount of time, with Aku Aku being placed on Crash's face during this period. He is the deuteragonist of the series, as well as a father figure to Crash, Coco and their friends.
