The Utility Belt is the iconic storage device used to house most of Batman's Gadgets like the Batarang. The exact contents of this belt are not known because Batman usually changes it to suit his needs. His uncanny ability to carry unusually appropriate tools is legendary. Batman's enemies are especially interested in the utility belt as they believe it will give them an advantage over him, but the belt's pockets are locked and only Batman knows how to open them. Occasionally, the utility belt is depicted as having defense mechanisms such as electric shock or stun gas in order to prevent tampering.
