Jerry Siegel is most famous as the creator/writer of Superman though he created a lot more than just the man of steel. Another comic he created after the incredible success of Supes is a comic he wrote for artist Bernard Baily called the Spectre. Like Superman (or at least the way Siegel originally wrote him), the Spectre is really hard on criminals though instead of having super strength and the ability to leap tall buildings in a single bound, the Spectre was just that, a specter or ghost, that had supernatural powers. Siegel was continually coming up with creative ways to punish evil-doers. And there lies the fun of the strip, the fancifully seditious ways that the Spectre comes up to deal with criminals. In the case of Zor, they both are super powered super-natural beings and so Spectre has work ahead of him.
