Williams (ウィリアムス) is a recurring enemy in the Double Dragon series. A quite common member of the Shadow Warriors, Williams is the first enemy that the player faces in the original Double Dragon. He is notably seen during the opening sequence, being the one who punches Marian in the stomach and carries her away with the rest of the Black Warriors. Williams' techniques include a body blow (the same one he uses on Marian) and a jump kick. In addition to fighting unarmed, he sometimes carries a weapon such as a baseball bat, a throwing knife or a dynamite stick. He also teams up with another enemy Roper.
