Batgirl also uses batarangs. Nightwing, a former Robin, is known to use his own modified batarangs called "Wing-Dings", which are styled after a bird. Tim Drake, the third Robin, also possesses his own 'R'-shaped shuriken. In an issue of "Teen Titans" (Vol. 3), Drake claims that he hid the costs for shipping a Batmobile from Gotham City to San Francisco in "the batarang budget", which he tells the others is "bigger than you might think". The current version of Batwoman uses foldable S-shaped throwing weapons stored in two sets of three on her gauntlets; these can be removed and thrown by hand, launched pneumatically, or used as forearm-mounted blades. Catman also uses weapons inspired by Batman's and calls them "catarangs". Like Robin, Anarky, an occasional antagonist of Batman, also makes use of shuriken formed after his own gimmick, the "circle-a".
