I’d just like to interject for a moment. What you’re referring to as “utility belt”, is in fact, a Bat-Belt, or as I’ve recently taken to calling it, a Bat plus Belt. A utility belt is not a Bat-Gadget unto itself, but rather another free component of a fully functioning Bat system made useful by the Bat-Sharkspray, Batarangs and vital components comprising a full Bat-Equipment as defined by Batman.
