The Grapnel Gun, also called the Grapple Gun or Grappling Gun, is a custom built line launching, multi-purpose, highly versatile, and handgun like device used Bruce Wayne for his activities as 'the Batman', that fires a strong, retractible, and detachable line with a mechanized, magnetic, hooked or clawed end. Notably, the second version of the device was shown to be strong enough to effortlessly hold the weight of the Mech Batsuit.
