Protodermis

Protodermis was a common substance in Bionicle. It has a silvery, metallic appearance and texture. It was commonly mined by Matoran, for everyday usage. It was essential to life in Metru Nui and other densely populated areas, because it was used to make many intrinsic things, from Kanohi to Widgets. There are a few known types:


 * Solid: Hardly compressed Protodermis in solid form.
 * Liquid: Protodermis in liquid form.
 * Energized: The most exotic type, because it causes bizarre mutations and enhancements in power, that is, if that is the recipient's destiny--they melt and die if it is not.
 * Molten: Super-heated protodermis with lava-like properties that burns anything in its path.
 * Crystalline: This type of protodermis can only be formed in two known ways. If six Toa combine their elements together or by the "The Shadowed One". It is strong enough to restrain a Makuta.
 * Protosteel: An alloy of protodermis, and the strongest of all. In the form of a weapon, it can shred through Makuta armor.
