This was a series of scribbles with the theory of "What if the Toa Mata/Nuva became Turaga?" after noticing that the Phantoka Matoran wore noble versions of Pohatu, Kopaka and Lewa's masks (I've been out of the loop with Bionicle for a while, and had just gotten back into it ^^; )
So, to start off here's Lewa, Kopaka and Pohatu.
Then there's Onua, Gali and Tahu. Had to do some redesigning of the masks here as they didn't get official Noble versions. Onua's is a simplified version of his Mistika mask, while Gali's is a mixture of her Mata, Nuva and Mistika masks. Tahu's was done with Turaga Lhikan in mind, with some minor elements of his Mistika form.
I also gave them their Nuva Symbols and silver versions of the Turaga's mechanisms, just for that little bit of distinction.
