I don't remember the lore for anything I loved as a kid before superheroes. Except maybe Ghostbusters, but there wasn't much "lore" there lol. Transformers, Sonic, Power Rangers, Teenage Mutant Ninja Turtles....I remember loving those to death, but if you quizzed me about the lore, I'd utterly fail. I feel like "lore" and world-building is only something that starts to matter to us in our fictional faves as we grow up, so we only keep up with it IF we keep enjoying that property as we age. As kids, we're pretty much just focusing on the funny characters, flashy visuals and sense of adventure. Or maybe that was just me lol.
