I hate the trope where a superhero is portrayed as the only or first hero in their universe. For example, in Sam Raimi’s Spider-Man and The Amazing Spider-Man movies, Peter Parker is literally the first and only superhero. The Arrowverse did the same thing, making Oliver Queen the first vigilante, and in Superman & Lois, Superman is the only superhero who exists.

Personally, I’ve never liked that approach because, in the comics, superheroes and metahumans have been around for centuries. James Gunn’s Superman even acknowledges this, saying metahumans have existed for about 300 years — which lines up with the comics and the main Marvel 616 universe.

I see Superman as the “Michael Jackson” of superheroes — he’s the archetype, the most iconic and influential, but not the first. There were plenty before him. That’s one reason I’ve always had an issue with the Arrowverse implying heroes only appeared after the particle accelerator explosion in The Flash.
