Command Materia (コマンド, Komando?) are a type of Materia in Final Fantasy VII and Crisis Core -Final Fantasy VII- that allow the character to gain extra battle commands when equipped. Command Materia are yellow.
Command Materia allows the user to equip various commands to use on their menu, which have mostly damaging effects to opponents. All Command Materia have no Status traits when paired with the Added Effect Support Materia, and have the Hidden element when paired with the Elemental Support Materia.
Command Materia are not treated differently from Magic Materia in terms of menu selection. Rather, any command ability equipped to Zack can be used in one of the four ability slots. Command abilities are normally offensive or related to items.
Materia means "matter" or "substance" in Latin, Spanish, and Italian; it also means "subject" in Italian and Spanish, and is the ascendant of Portuguese "Matéria".
