In Christopher Nolan’s The Dark Knight, he used the grapple gun to catch Heath Ledger’s Joker from falling to his death, and in Batman v Superman: Dawn of Justice it was the first weapon he pulled out of his arsenal while engaging Lex Luthor’s men on his mission to rescue Martha Kent.
Batman’s grappling gun has become one of the most fundamental aspects of his arsenal over the years.
With the character set to return when Justice League finally debuts in theaters, we have a very distinct feeling that the grapple gun will once again factor heavily into his unique style of crime fighting.
Not only does the gadgets allow him to ascend and descend buildings at incredible speeds, but he has also found a number of alternative uses for it in recent movies.
