The Triple Barrel Grapnel is a multi-fire blaster that is able to fire up to three darts at once. It features the use of a system similar to a Nerf intelligent air restrictor that allows it to fire all darts loaded in the muzzle, whether it is full or not. A small Batman logo can be seen on either side of the blaster.
