Let's say the movie General Zod succeeded in turning earth into Krypton(all humans are dead), but the codecs and Superman gets vaporized somehow. It's forever lost to him. Zod has a few women on his team. The females also have the same goal of repopulating. Why not have them birth babies? I don't think they would to mind since they all care about this one goal. I know it would be natural birth, but Zod could brainwash the children to be anything he wants.
Did he have one woman on his team? I can't seem to remember.
