So, we know that the Bionicle universe shares [at least] some properties, particularly those of physics, with our universe. (Gravity, water (and therefore chemicals, though those aren't really talked about), etc.) And, particularly because of the chemicals part, things can take three forms (not counting plasma, yo), liquid, solid, and gas. We know protodermis can be solid and liquid, but we've never seen it as a gas, that I can think of. Also, we know that things have to be either an element, or a molecule (well, not REALLY, since there are levels below those, but you know what I'm saying). What would protodermis be? I'm tending more towards element, just because of its properties. Also, energized protodermis could be like Prt1- or something like that, which would make it more reactive, probably. So, what are your thoughts on this? Obviously, this is all hypothetical.
