Bruce Wayne and his son Damian a pair of experimental jetsuit prototypes. They can provide artificially enhanced strength and endurance as well as short-range flight capability. The prototypes are considered too risky and expensive for operational military use, allowing the Waynes to utilize them for the family's Batman Inc. project. Utility belt and other equipment Batman's utility belt is his most characteristic prop, much like Wonder Woman's Lasso of Truth, or Green Lantern's ring. 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 compartments are locked and only Batman knows how to open them. There have been a few instances where the security has been bypassed: in the Justice League episode "Injustice for All", Lex Luthor managed to open the belt by subjecting it to intense electrical shocks and in an episode of The Batman "The Cat and the Bat" Catwoman stole Batman's utility belt and managed to open the capsules.

The belt is almost always yellow in color, and the look of the belt is usually depicted as having either capsule-like cylinders or military style pouches to store his equipment in. Following DC's 2016 initiative DC Rebirth, Batman's utility belt is depicted as being a black and yellow flat, compartmentalized belt. The array of devices Batman carries have become more complex over time. The simple coiled rope and batarang scaling equipment became a rocket-powered (or compressed-air-powered) grapple gun. The suit has also carried on different occasions a re-breather device, flash and gas grenades, explosives and a detonator, lockpicks, a signaling device for the Batmobile, electronic surveillance equipment (including video camera and monitor), a forensic kit for gathering crime scene evidence, a medical kit, a small toolkit, a homing device, a cache of money and, in early incarnations, a pistol in a holster. On any occasion where Batman anticipates encountering Superman, he has also carried (in a lead case) a Kryptonite ring given to him by the Man of Steel as a weapon of last resort (in some instances, Batman has acquired – or
