ProtoSteel

"Lewa yanked on the chains. They were made of protosteel, one of the hardest substaces in the universe, and so thick that even Pohatu would have a hard time breaking free by sheer strength alone."

- Narrator, Shadows in the Sky

Protosteel is the hardest known substance in the Matoran Universe, a rare type of Metallic Protodermis.

==History ==

Like all other forms of Protodermis, Protosteel was made by the Great Beings. Toa of Iron were given the ability to create and control the substance.

Protosteel has been used rarely, due to the difficulty in working with it. Artakha is one of the few known to be able to work with the substance, and create things out of it. It was also used in the Order of Mata Nui's experiments with the members of Ehlek's species.

Makuta eventually evolved from solid Antidermis into gaseous Antidermis encased inside Protosteel armor. They later hired the Nynrah Ghosts to alter their armor to take advantage of the Makuta's new form.

==Properties ==

Protosteel is the hardest known form of metal in existence in the Matoran Universe, and is conductive to electricity. It is extremely hard to work with, and only several beings within the universe can deal with it, including the Nynrah Ghosts and Artakha.

Because of its durability, there are only a few known ways of destroying or damaging Protosteel including:


 * Another Protosteel object
 * A type of armor-eating virus
 * Tren Krom's and the Shadowed One's disintegrator eyebeams
 * Pridak's teeth (formerly)
 * The heavy doorway between Mangaia and Metru Nui's dome
 * Intense laser/heat beams
 * A Visorak Keelerak's Rhotuka Spinner
 * A Toa of Iron using his control over metal to destroy it
