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.
No, but I watched it as a kid regardless.
