The repellant is seen in The LEGO Batman Movie as part of the Caped Crusader’s arsenal, but he didn’t have any problem with Dick Grayson touching it, as he deemed it “useless.”
There are a number of Batman ’66 references sprinkled throughout The LEGO Batman Movie, and we’ll discuss some more of them later in the list, but arguably the most notable recurring one is the Bat Shark-Repellant, that infamous spray used against a toothy adversary in the 1966 Batman movie.
How wrong he was, as later during the movie’s climactic conflict, Dick, now Robin, successfully used it against Jaws.
See, having the repellant came in handy after all!
