Aku Aku is the spirit of an ancient witch doctor who appears as a sentient, floating wooden mask. He looks over the Wumpa Islands as their benevolent protector and the Bandicoot family as their father figure. He has magically protected Crash over the years with his special powers and gives him important advice when the situation calls for it.
From Crash Bandicoot 3: Warped up to Crash Twinsanity, Aku Aku is voiced by Mel Winkler. In the games starting with Crash of the Titans, he is voiced by Greg Eagles.
