Jordan Ballor is less than thrilled with the evangelical bandwagon to baptize Superman as yet another in a long line of literary and pop-cultural Christ figures. Maybe it is a bit uncritical and perhaps a bit overdone. But I have to take issue with Ballor when he suggests that Superman is more reminiscent of Nietzsche's Ubermensch than he is of the Son of Man.
Having read my share of Superman comics through the years and having taken in many, many pop manifestations of the character, one thing is clear: Superman is not Nietzschean. Although he has all the power in the world, he has a prevailing morality that trumps his own power. A perfect example of the anti-Nietzschean aspect of the comic Superman is that he has virtually always refused to kill, even when a villain richly deserves it. He is also the type of fellow, who though often indestructible, has always been ready to sacrifice himself for his friends (and everybody else).
There are a couple of examples that go against the grain. For instance, in the lamentable Superman IV, our hero drops any pretense of respect for democracy and imposes his will on the globe when it comes to nuclear weapons. He simply throws them all into outer space. No word on whether he then intended to police every border where the Soviets might have had tanks ready to roll! I would argue this Superman is a version (a lefty-liberal Greenpeacey type) of the will-to-power superman, but he is an exception that virtually all fans would excise from the legend. Another example occurred in a graphic novel tracing out alternative worlds with a Superman. In one of the alternate planes, he sets himself up as a king. Pretty logical, eh? But again, this was the authors' funnin' around and not setting up a new idea of the hero.
