The Kanohi Komau was the Mask of Mind Control, a Kanohi that allowed the user to influence the mind of a single target, convincing them to perform a series of basic commands. However, the Kanohi could not allow a subject to violate their moral code and was ineffective against fully robotic organisms and some types of Rahi. The Komau also allowed the user to deliver a powerful Psionic pulse that temporarily left a target in a semi-conscious state.
