The Kanohi Kromi is the Mask of Memory. It enables the user to remember anything he/she has forgotten from his past experiences and events. For example, when using the mask you could remember any of your experiences since birth. The mask does not give an image of the event and it does not allow the user to learn anything. The Great version of the mask is also able to alter one's memories, like making someone forget something, or remember something they did not experience.
