Zebetite (also referred to as Zeebetite) is a powerful regenerative ore-like material located mostly in Tourian. It seems to be a powerful source of energy that powers the Mother Brain. In Super Metroid's Tourian, they are not restricted to the Pirate leader's chamber, and can be seen in several rooms throughout the Pirate HQ. The only times Samus has needed to destroy Zebetites is to get to Mother Brain in all of her encounters; although they can be destroyed with Missiles, Zebetites regenerate in a matter of seconds if Samus does not dispatch them quickly (also wasting precious ammuniton), making them excellent shields for protecting the Pirate leader. It is possible Zebetites are somewhat living tissue. They are featured in Metroid, Super Metroid, and Metroid: Zero Mission.
