Kraa-nui

Maybe some masks are just duds. I think that combining disks with any number of combinations would lead to some being down right useless, some being legendary, or some being in between. Also there would be many masks with slightly similar powers just rearranged a bit. And I just realized maybe not all kanohi are created equally, there could be varying degrees to their manufacturing, which would lead to some having parts of other kanohi powers. Only some thoughts.

I'd like to point out, the mask of creation, as shown in the video, is on a pedestal, not possessed by anyone, and elevated to being even more legendary than it was. Wondering where this would put Artahka. Just something to think about.

I was thinking about this recently, and thought they were created to aid in matoran labor, like the ussal crabs. Also they would be part of an ecosystem inside of mata nui, which is some what important.
