I always liked the opening for the Beetlejuice cartoon about 200x more than I liked the actually show.
Some other cartoons with awesome openings: Superjail! and Metalocalypse.
I remember the Beetlejuice cartoons then I remember a little bit of at some point I don't know which channel but they made Back to the Future Animated series

I never did watch Batman: The Animated Series much as a kid, but I do remember coming home everyday from school just in time for the start of Inspector Gadget.
I think the Teen Titans opening would just simply alternate between the two of them. After looking it up, it seems when the Japanese opening is played, the episode is more comedic. And when the English opening is played, the episode is more serious.
