Superman wouldn't be a threat to anyone in Skyrim, since Superman got his powers by having his Kyrptonian DNA absorb the radiation from the Earth's yellow sun. It is already proven that if he instead landed on a planet with a red sun that he wouldn't have any powers. With that in mind, know that the sun in Mundus does not have radiation at all, as it is just pure magic (which we have already established is Superman's weakness) pouring from Aetherius into Mundus. Therefore, in Skyrim, Superman would have no powers at all, and would be lucky enough to not instantly die upon exposure to it.

But if we're going to pretend otherwise, then Wabbajack would be the best course of action, since at best it would instantly kill and at worst it would turn him into a Dremora, which would still be significantly weaker.
