In addition to all of the above I recommend The Dragon Prince on Netflix, there’s a few LGBT characters on there, a couple if which play very prominent roles in later seasons. Season 4 drops off in quality a bit but it picks back up in season 5.
Star Trek Lower Decks has a bit of representation too, and you don’t need to like Star Trek to enjoy it.
The last episode of Ghost and Molly McGee nods to one of the big supporting characters being lesbian or bi.
Craig of the Creek is for younger audiences but has a bunch of lgbtq characters, including a lesbian kiss scene! It’s very good at all sorts of representation.
One of the main characters in The Great North is gay and out. It’s a fairly chill comfort show I’d say but different from the ones above.
The main protagonist of Dragon Age: Absolution is a lesbian but that’s not specifically a central part of the story.
There’s a bit of representation in Vox Machina, but be warned it’s quite violent and bloody at times. Same for Castlevania but my god that was an amazing show. There’s even a MMF sex scene, but I won’t give away much more on that.
Those are some that come to mind for now but I’m certain there’s more. Enjoy!
Edit: I just noticed you didn’t list Adventure Time. If you liked all of the cartoons you listed you -must- watch Adventure Time! There’s a wee bit of lgbt rep in there too.
Lots of things I’m really interested in are looked down on by other adults I know. I love animation but it’s seen as something for kids. I love video games, but that’s for teens, incels and nerds. And I love birdwatching, but that’s for boring old people. Oh and also whatever my ADHD is making me hyperfocus on at any given moment. I could talk about any of those topics for ages, but more often than not people aren’t interested, so I keep it to myself.
