The Dark Knightâs goal is to not only seek vengeance for his parentsâ death but to strike fear into the hearts of all criminals. In many Batman stories such as Dennis O'Neilâs âThe Man Who Fallsâ, Bruce Wayne exhibits chiroptophobia (fear of bats) and conquers that fear by placing the same terror into wrong doers. Batman uses this fear into one of his gadgets thatâs more rare than many realize: the Sonic Bat Call. Created by Frank Miller and David Mazzucchelli, this Batman devise debuted in the 4 issue arc âBatman: Year Oneâ in Part Three, originally published in Batman (Vol 1) 406 in 1987. In order to create a chaotic diversion and escape the attacks from the Gothamâs SWAT team, on the heel of his boot Batman presses the ultrasonic signal button which calls live bats from his Batcave to fly to his exact location (panels 1-3). The young Caped Crusader uses this opportunity to ride away from the GCPD and onlookers such as Selina Kyle (panel 4). Millerâs âYear Oneâ was a clear and heavy influence for Christopher Nolanâs 2005 film âBatman Beginsâ. Just as in Mazzucchelliâs intense panels, in the film this bat calling device is located in the Caped Crusaderâs boot heel, as a form of protection and cover for Batman during a getaway (panel 5). In the animated film adaptation of Batman: Year One, this comic plot is brought to life as well. Although not rarely used within the Batman mythos, the Sonic Bat-Call reinforces the shadowy image of the bat and the Batman himself. We will discuss more of Batmanâs arsenal in our session tomorrow so stay tuned and thanks for following History of the Batman! âđŒđđŠđđŹ
