If I were to ask you about Superman’s magic, you’d probably talk about his ability to fly, his super strength, the lasers he can shoot from his eyes. You may go from there to his invincibility and perhaps some of his lesser (and more inconsistent) powers. But if we stick with those four, we’ve got a pretty strong setup for what Superman is capable of doing.

However, is this what makes Superman interesting?

I’d put forth that it is not. There are lots of people with magic powers who can fly and who are invincible. There are a lot of strong, fast, or smart people. What makes Superman interesting, then? Two things: his code of ethics and his weakness to kryptonite.
