Level 55 - Aku Aku

Crash Bandicoot is a series of platform video games published by Activision after first being developed by Naughty Dog and published by Sony Computer Entertainment. Initially created by Andy Gavin and Jason Rubin, the series was developed for its first four years by the video game company Naughty Dog. Since then, the series has been given to numerous developers. The series centers around the conflicts between a mutated bandicoot named Crash Bandicoot and his creator, Doctor Neo Cortex. Crash acts as the main playable character of the series, though other characters have had occasional player access, most notable Coco Bandicoot and Doctor Neo Cortex. Out of the numerous characters in the series (numbering over sixty), only a few have significantly contributed to the story of the series.
 

Aku Aku is the guardian of the Wumpa Islands and the father figure of Crash and his friends. He is voiced by Mel Winkler in his English speaking appearances up to Crash Twinsanity, and by Greg Eagles in Crash of the Titans and Crash: Mind over Mutant. He is voiced by Kenichi Ogata in the Japanese versions of his speaking appearances up to Crash Twinsanity. Aku Aku is the spirit of an ancient witch doctor encased in a floating, wooden mask. When he sensed Crash's mission to stop Doctor Cortex, he scattered copies of himself throughout the Wumpa Islands in an effort to aid him in his mission. Whenever Crash possesses an Aku Aku mask, he will be shielded from one enemy attack or contact. Collecting three Aku Aku masks gives Crash temporary invulnerability from all minor dangers.
