As a ring, Zaruba acts as Sword's darkness sensor and tracker. However, he has a greater role than other incarnations. He's also the key to Sword's motorcycle. Once transferred and activated to the motorcycle, Zaruba becomes the motorcycle and the ride becomes his extended body. When Garo activates his armor, the motorcycle also becomes armored. Capable of melee combat, the motorcycle has a pair of mechanical grappling arms with the physical strength to lift a truck and throw it across the field.
