Ok, I think I put this topic under the right form so here's the deal, I just have theory about the Mask/Toa of light.
I actually believe that The Toaa of light is mysterious and no one knows who he is. EXCEPT for Takua! I believe that Takua is a Matoran most all of the time and then when he puts on the mask of light he becomes the 7th Toa! I mean it makes sense. And when he takes it off he changes back to a Matoran state. I just wanted other people's oppinions but that is my theory. Tell me what you all think about it!
