Gemini Laser (ジェミニレーザー Jemini Rēzā?) is Gemini Man's Special Weapon. It was based on the "reaction element" (反応素子 "reaction element"? no official translation, alternatively "response component/device") discovered by Dr. Light. The Gemini Laser shoots a blue energy beam that reacts to the opponent's thoughts, and it reflects when it hits substances that do not have thoughts, like walls.
