Special steel

Special steel (鋼材) is a sturdy material from the Mega Man series that is known to be widely used in armors such as the helmets from Metalls and shields from Joes, and is also used in Mawverne's outer casing. Objects made with this thick material can repel almost any attack. While many robots and objects have similar properties, such as Shield Attackers, Circring Q9, and the Proto Shield, it is unknown if they use the same material.
