The Angry Beavers was by far my favorite.

Also loved Harvey Birdman: Attorney at Law.

Oh! Courage the Cowardly Dog

I loved Cow and Chicken. The Red Guy was the best, I loved how he had lil butt cheeks you could see and went by names like “Mr Pants”.

The last one that I can think of is probably Gundum Wing, although I watched a lot of Flinstones reruns growing up as well. Almost everything in both of them went way over my head as a kid.

So Hysteria was a bit hit and miss in terms of how enjoyable it was, but it did land at a time when I was able to record from TV and use it to aid some school presentations. Every single time the teachers would ask where I got this from.

Avatar: The Last Airbender. I could rave about it all day.

Also Gravity Falls like @swordgeek@lemmy.ca said.

I never watched Justice League much as a kid, but my wife re-introduced it to me as an adult and it’s a pretty great mix of kid-friendly superhero stories with fairly mature themes and plotlines.

Additionally, a less awkward term than “kidult” is just “family entertainment”. Shows/movies/books that can be enjoyed by a wide spectrum of ages.

Do The Powerpuff Girls fit in this category? Really gory and with some inappropriate themes especially since they’re supposed to be little kindergarten age girls. Loved the show, I occasionally watch an episode as an adult.

Was also a fan of Billy and Mandy, nice to see that one as the post opener.

As for other shows, as a kid I loved watching Aeon Flux and I am still not sure wtf was going on in some of those episodes.

Moral Orel is another great show, smart and witty, although I discovered it as an adult.

Invader Zim

I still come back to this every once in a while. I loved the dark humor plus the childish humor mixed with some adult humor though I don’t feel it was on the same level as other shows of the same time as I’ve rewatched it, which has surprised me.

Adventure Time.

Gravity Falls. A masterpiece of storytelling, wrapped up in family-friendly horror.

Btw, if you’re still into animated shows, there’s a few communities around for them.

General animation:

!adult_animation@lemmy.world

!animationafter30@lemmy.world

Japanese animation:

!anime@ani.social

Give’em some activity if you’re wanting to share and talk about some animated stuff you’ve been checking out!

Star Wars: Clone Wars, it has super inappropriate war crimes.

Probably Animanics, though I was grown up before I watched that. Before that, I suppose Beavis and Butthead and even Simpsons were considered edgy.

Mega Babies

Horrifying and the theme song is straight out of your worst nightmare but its part of our history lol

Futurama - though I expect that’s showing my age.

Ren & Stimpy
