The O-Part spear belonging to Dofuwa Longinus. In the normal state initially shown, it can create sonic booms by piercing the barrier of air, and can even diffuse aerial attacks like Kirin's Air Fang. In its activated state, the spear changes shape and can control light. Known abilities with it are Infinite Light World, which creates a dome that reflects light from every direction so that everyone within cannot see anything, and Longinus Spear, where Dofuwa can become a being of light with his spear to attack his opponents. As seen by Amidaba's use of her Rainbow O-Part, Dofuwa can also revert to his human form after use of this attack.
