The Guardian Fire Spear was Kakamu's primary weapon which was transformed from his Matoran spear. He used it to channel his powers. It was disintegrated during a battle with Voporak but Kakamu managed to construct another. He used it until his armour exploded. The current Guardian Fire Spear was floating in-between dimensions until it was found by the Fellowship of Kakamu. It is currently in the Realm of Shadows.
