I say Admiral Kizaru from one piece. Kizaru possesses the power of the Pika Pika no Mi, meaning 'glimmer' or 'light,' a Logia-type Devil Fruit. As a Logia-user, he is able to let objects pass through him and reconstruct his body from energy particles. He is capable of moving at the speed of light, and all of his attacks are based on the element of light; such as firing energy blasts from his fingertips or feet with extreme precision. His power is very destructive, causing huge explosions and easily destroying buildings. He also has the ability to reflect himself, essentially moving from one location to the next at the speed of light, making him the fastest man in the world. He can also make an energy sword out of pure light, which can stand up to heavy "Haki" based attacks; as seen when he was fighting Silvers Rayleigh. Kizaru has named several of his abilities after the three great treasures of Japan.
