He's about the most definite person I know. With him, good is good, evil is evil, and there's no room for any middle ground.
He's also incredibly masculine – not just in his physique, but in his manner, his attitudes, everything. It's easy to seen why Lois is so besotted with him.
And singular – yes, he's that, too, and not just because he's the last member of his species. That dignity of his, that passion for righteousness, would stand out even on a planet full of Kryptonians.
Yes, that's Kal in a nutshell. Definite, masculine, singular.
No wonder his surname's El.
Disclaimer: DC Comics took all the rights to Superman, without even considering if I would want to use it. Shameful, but there it is.
Author's note: Before you ask, the narrator of this story isn't meant to be anyone in particular – although I think it becomes rather interesting if you imagine that it's Faith.
