Superman has been in continuous publication for over 80 years, and DC Comics has tried everything imaginable to keep readers coming back month after month. Supes started off just leaping tall buildings and shrugging off bullets, but eventually he became so omnipotent that he could fly through space unaided and hang out in the heart of the sun. He spent decades pursuing Lois Lane before finally marrying her.1 He lost his powers, got them back, got different powers, lost those, and so on. He died once or twice, although nobody in comics ever really dies. Hell, at one point they even gave the Man of Tomorrow a mullet. Back in the ‘90s, he looked like a flying Billy Ray Cyrus.
How else can you make Superman interesting? You turn him gay. Well, sorta.
