Batarang

A batarang is a roughly bat-shaped throwing weapon used by the DC Comics vigilante Batman. The name is a portmanteau of bat and boomerang, and was originally spelled baterang. Although they are named after boomerangs, batarangs have become more like shuriken in recent interpretations. They have since become a staple of Batman's arsenal, appearing in every major Batman television and movie adaptation to date. Recent interpretations of the Dark Knight finds additional motivation to use the batarang as a ranged attack (alternative to firearms, which he rejects outright due to the circumstances of his parents' murder) and is used primarily to knock guns out of an assailant's hand.
