I’m seeing that “science says Superman should be black” article circulating again, and my guys, no it does not. Science says Superman cannot exist, that’s the only thing it’s saying. He can be any color the artist wants; he was created by two white Jewish men, so that’s what he looks like. Can he be black? Absolutely, why not? It’s a comic, he can be anything.
But really, think about it: if he’s black, with all the beautiful melanin that he deserves, do you really think that would lend itself to absorbing sunlight? With all the mechanisms that use melanin to keep that from happening? Really? If anything he should be white-white, to absorb all that sunlight and have it stored, untouched by melanin keeping it from his cells. So don’t try and use too much pseudo science to justify a MoC Superman. Absorbs sunlight, flies because of Earth’s lower gravity, blah blah blah, etc. That’s the only justification needed: because you want him to be.
