Denki's sharpshooting equipment includes a three-pronged Shooter that attaches to his forearm, orange targets contained in yellow clips, and a pair of blue glasses.
In order to utilize his Electrification Quirk without injuring everyone around him, Denki requested Mei and Power Loader to create a way for him to aim his discharges.
The disks fired by the Shooter (called Pointers) will stick to the point of impact. As long as Denki is within ten meters of the target, his electric discharges will be drawn to the Pointer of his choice, concentrating the discharge into a straight line. If he needs to select multiple targets then he can use the dial on the Shooter to select a Pointer and figure out exact locations using the glasses.
