8. The Batarang
One of the most iconic Batman gadgets ever; the Batarang has taken many forms and shapes over the years. Some versions had ropes attached and some had computerized aiming systems. Regardless of their shape and function, there isn't a Batman film in existence that doesn't showcase the latest version of this legendary gadget. Personally, I love the version above which is more like a throwing star. Since Batman was trained in several martial art forms, a throwing star type of weapon makes the most sense.
