Superman

Why it matters

This is the cleanest early source for the superhero template as mass culture knows it. Cape, chest symbol, secret identity, impossible strength, city-saving goodness—that whole package radiated outward for decades. That alone gives it a big case. But the extra push comes from language: kryptonite escaped the story and became a normal word for “the thing that weakens you.” That is huge for a work’s survival in ordinary life. I keep it just outside the upper band because a lot of the public image was amplified by later film and TV, but the source is still doing the heavy lifting.
