When superheroes make the transition from comics to TV animation, it's always interesting to hear what kind of theme music they get. Songs with lyrics that explain who the heroes are can be fun, but they can also go awry. Instrumental tracks can be boring if you're not careful, but if they're well-executed, they can do a great job of creating just the tone you want for your cartoon.
I've put together a chronological list of nine memorable theme songs from TV superhero cartoons. Obviously I can't include them all, but I expect to see in the comments which of your favorites I've left out.
