However, it should be noted that Pattinson’s Batman can be seen using a grappling gun in a scene from the trailer for The Batman.
In those movies, much like in modern comics, Batman was shown to have a great dislike for firearms, since they reminded him of the gun that fired the bullets which took his parents’ life.
The Batman from the Flashpoint Paradox comic series was a gun-toting vigilante who was secretly Thomas Wayne.
The full ensemble was worn by a stuntman who had donned the bat costume while shooting a scene for the film.
