So I was thinking...what exactly is protodermis? I don't know that the bionicle universe is even constructed in the same way as ours (atoms, molecules etc) but if it is, then is protodermis an element, a compound or a name for a group of elements? Everything in the MU is made of it, even the 'elements' themselves so it must be able to come in many different forms like carbon. Anyway, tell me what you think... -Silo
