I was aware of most of that. I was under the impression that the Inika's Kanohi were changed by their Toa transformation. It's not that the masks themselves change, but rather their masks are swapped when transforming into Toa be the powers-that-be. I mean, if the Ignika can change a Toa's current mask, then so can a combination of a Toa Stone and the Red Star's presence.
