Hello. I'm the Great Matragon, long time Bionicle fan and forum lurker. Well, this has a little bit of history behind it. You see, not only am I a Bionicle and Lego fan, I'm also a Transformer Fan. I even have a Transformers-based Webcomic, called Transformers Nexus. But you may not be interested in such facts, so allow me to explain further.
You see, some issues of my comic don't focus on the Transformers at all. Rather, they focus on other characters in their crazy little universe. And, for anybody who wants to know why I bring this up, that includes the Toa Mata, whom you may recognize from the first known Bionicle Saga, and are widely considered fan favorites.
However, having biomechanical beings that look more like robots then anything else can be a little confusing for both the crowds that walk the streets and those readers not 100% familiar with the franchise. So, to compensate, I gave these Toa a little trick other then masks that do stuff and elemental manipulation. That trick is the ability to assume human shapes so they can fit in better with the crowds. Like Kamen Rider... in reverse, or something.
Anyway, enough about that, here're the bios for these amazing redesigns (Matter of Opinion.)
