Since we seem to be talking about favorite cartoons from the past. How many watched the Disney produced show
Gargoyles which first aired back in 1994.
An excellent blend of magic and science fiction. Gargoyles tells the story of a race of creatures that by day turn to stone but by night awaken to fight and protect the people they care about.
In ancient time, Goliath (the main hero) and his clan protected a castle. One day they are betrayed by some of their human friends and many of the clan are destroyed. Only a few survived and fin themselves placed under a curse that keeps them asleep for 1000 years. Waking up in modern day New York, their story continues.
Much like Batman:The Animated Series-this show would often get dark and deal with more adult situations then your average afternoon cartoon. Topics such as racism , homelessness and gun violence were dealt with often with realistic aspects.
People could get seriously hurt, even die. Characters where complex and underwent serious development.
Coupled with that, Gargoyles would have everything from magic, to aliens, to mutants and outcasts. In the end, the show formed a comic book style universe that could compete with anything Marvel or DC put out.
Wonderful designs and animation.
The only thing that might put people off is that the show did have a strong continuity to it. While there were plenty of stand alone episodes, its best to start with the first episode and work your way through the show in order.
