Joe Gravano is a mob boss in Starling City. He is wanted by police for 39 counts of murder, racketeering and smuggling.
Gravano was kidnapped by Cupid, despite usually being heavily guarded, and tied up in a Sherwood Florist greenhouse to lure The Arrow. He was hooked up to a bomb around his chest, but The Arrow was able to cut a tripwire holding him up and throw the vest away, before forcibly making it explode away from them. He expressed his unusual happiness to see the vigilante, having been saved by him, but The Arrow simply knocked him out.
