I don’t even know why I’m anwsering this……. Anyways, no, Rock do not nor any other reploid. They do not have reproductive devices because they don’t need it, it would be hard for Dr. Light to make a cylindar like thing and make it extend and retract, not considering it is useless and adding weight to Rock. And since all reploids are based on X and X is an improved version of Rock, they do not have it either. In ZX era and afterwards however, some people are created by mixing Reploid and human(not by sexual reproduction because reason above), and they are also called Rockmans since they are human as well, they do have reproductive devices. If you are talking about the EXE and starforce, any net navis do not have reproductive devices, but later on in the star force series they to. net navis do not have it because they are programs, including Saito, who where Netto’s brother but was turned into a program after he died, and since he is a program, he too have no reproductive devices. In starforce, Rockman is a combined character between a human, which have reproductive devices, and a alien, which should have reproductive devices as well, and therefore Rockman should have reproductive device/devices.
