After shooting his own right arm as a result of brain-hacking, Batou is fitted with a new DNA-matched prosthetic arm with a shotgun hidden inside. He is depicted as being tougher than in the other "Ghost in the Shell" incarnations, when he is seen to shoot two live grenades and survive the blast, and withstand a substantial leap down the shaft of the Locus Solus factory ship. In both films, Batou carries a gun dubbed a "Jericho 942," based on the real Jericho 941 made by IMI but chambered for .50AE. In "Innocence", he is also seen with a compact S&W pistol and a small semiautomatic shotgun. The "Innocence" prequel novel, "After the Long Goodbye," notes that Batou's S&W pistol is chambered for the .40 S&W cartridge.
