Goro Goro no Mi (Ruki)

Introduction
The Pika Pika no Mi is a Logia-type Devil Fruit that allows the user to create, control, and transform into light at will, turning the user into a Light Human (光人間 Hikari Ningen). It enables the user to move at the speed of light and transport him/herself by means of reflection. "Pikapika" is an onomatopoeia of glimmering or shining light.

Strengths and Weaknesses
The fruit's major strengths, like other Logia types, allows the user to become the element they control. In this case, Borsalino is able to transform into light. Borsalino is able to utilize light-based attacks that range from shooting laser beams from his hands, fingers, or feet (capable of causing massive explosions), to partial transformations that enable light-speed physical attacks; all of them being very devastating. He is also extremely accurate, being able to hit the key to Ace's handcuffs from a far distance.[3] Borsalino has shown trained reflexes that allowed him to avoid damage even in a surprise attack. He is also able to avoid normal attacks by turning into light and allowing the attack to pass through him completely like most Logia users. Borsalino is also able to do planned travel at the speed of light[4][5] and is able to reflect himself to any desired location.[6] Due to this fruit's power, Borsalino is possibly the fastest man in the world (as nothing is faster than the speed of light).

Silvers Rayleigh has used Haki to suppress the power of the Devil Fruit, nullifying Borsalino's intangibility, and allowing him to divert his attacks, as well as cut him with a sword. Also, considering it is light-based, his attacks and abilities can only travel in direct, straight lines, however, it has been shown that they can be reflected off surfaces to go around corners (Yata no Kagami), though said technique takes time to prepare and as such he can be stopped by a fast enough opponent (as Rayleigh managed to slice through the beams). It could be noted that Borsalino takes much more time than the speed of light to charge his lasers, and he even allowed Zoro to be rolled away from his charged kick. However, this could also be because of Borsalino's laid-back personality, because he is shown firing two lasers through Marco the Phoenix immediately after charging his in the Battle of Marineford. Other than that, the user is also affected by the standard Devil Fruit weaknesses.
