The Kanohi Rua was the Great Mask of Wisdom.
These three Mask powers could only be activated individually as the use of a Kanohi required a link between the mind and the Mask.
Of the three Kanohi used to form it, the Rua took the appearance of a Great Miru.
- A Kanohi Rua cannot exist in Noble form.
- If a Rua was to be removed from the Toa Kaita that was wearing it, the mask would not unmerge until the Toa Kaita did.
