I’d rather sleep with Batman than Superman but I’d also prefer Clark Kent to Bruce Wayne. I’m not entirely sure why, honestly.
See, this is interesting, because I’ve actually got some thoughts on why that might be. You’ve selected the two real personas. Bruce Wayne died that night when he saw his parents die, and Batman was born. The Bruce Wayne the public sees today is an act, just Batman acting stupid, spoiled, and irresponsible because no one would make a connection between Batman the genius and Bruce the spoiled oaf.
Similarly, the Clark Kent persona is Superman’s true persona. He really is a big awkward goof, and when he’s Superman, he’s just acting cocky and badass so people don’t realize that (for lack of a better word) mild-mannered Clark Kent is really the Man of Steel.
I just thought that was interesting, that you prefer each of their real personas to their fake ones. Here’s the real test, though: Batman or Clark Kent?
