>>107457360I think you're thinking of the specific Sailor Moon clone brand of magical girl/superhero blend. And that makes sense because that's become its own genre and kind of eclipsed everything else in the popular consciousness, especially in the West. But the magical girl subgenre goes back to the '60s (some people even say the '50s).
Not all of them are superhero comics. Until relatively recently most of them were silly comedies. Think Sabrina the Teenage Witch and Wendy Witch. In terms of what the characters were like, they typically resembled Zatanna more than anything else. Having been influenced by things like Mary Poppins and (especially) Bewitched, they frequently featured girls, often dressed as cute, Halloweeny versions of stereotypical Western witches, who can do basically anything with their magic, generally through some kind of incantation or gesture. Sometimes they mess them up or they have unintended consequences, with comedic results. There are lots of other things they could b, though. It's a very loosely-defined genre.
That said, yeah, I get your meaning. You see a lot of Sailor Moon influence but you'd think they'd be more aggressive about trying to copy it. There were some efforts to get in on the Sailor Moon train early on that didn't pan out, so maybe that sort of explains it.

More recently we've been seeing more, though, as people who grew up with Sailor Moon enter the industry. There were those Amethyst shorts. The new She-Ra and the Princesses of Power has notable influence from Sailor Moon. And of course there's this.
