Batman VS Gunsmith
Gunsmith got his name after building a gun and silencer out of materials bought from an airport electronics store. Kinda reminds me of that moment when Captain Cold rebuilt his cold gun using materials from a hardware store – this was during the Forever Evil event.
As impressive as Gunsmith’s skills are, Batman makes short work of him. Gunsmith’s no where near the caliber of the more deadlier Deadshot and Deathstroke, both of whom Batman’s defeated in the past.
