Legendary Kanohi

Legendary Kanohi were very powerful Kanohi that controlled fundamental forces of the Matoran Universe. They were far more powerful than other Great Kanohi. Unlike normal masks, which became useless if cracked, Legendary Kanohi gave off small amounts of their power when cracked. Legendary Kanohi were usually too powerful for Toa to control for very long.

Known Legendary Kanohi
The only known Legendary Kanohi were:
 * The Ignika, the Mask of Life
 * The Vahi, the Mask of Time

Trivia

 * Despite having a different power level, Legendary Kanohi still bore the title 'Great', like Great Kanohi.
 * Unlike other masks, touching the Kanohi Ignika would result in disaster unless one was destined to hold it, like Matoro.
