Try "Superman" instead.

I'm not a historian, and I've wondered whether the historical background for the comic (conceived in the early '30s I think?) included some of the racial overtones that were more pervasive at the time. I don't know how influential Darwin and Galton were scientifically at the time, but even if they weren't current in scientific circles (which I kind of doubt), certainly it's hard to ignore that the ideas were "in the water" so to speak.
