Batman
The Animated Series is well known for challenging the very stereotype of cartoon heroes. There are not many shows that have the same gritty and dark atmosphere, almost limiting itself children, like Batman. The intro theme is a perfect reminder to the revered cartoon show.

Teenage Mutant Ninja Turtles
How is it that you get a lame name for a cartoon and make the name so catchy just by singing the title 3 times? TMNT of course is one of our favourite cartoons and I remember whenever I catch an episode I would put my Michaelangelo mask on. Ah..yes, best memories.

Transformers Season 2
I remember whistling to the theme while I was waiting to watch the film. The season 2 theme song was memorable because it has beat, very catchy, real heroic in a way and it does not sound like robots singing (season 1). The song is stuck in my head for ages!

X-Men
Once, I believed no other cartoon can beat the X-men. Whether it's superman or spiderman, no one can beat the X-men. Whenever the theme song plays on television, it's like a quick jolt in my ears where I will come running to catch one of its episodes. Plus, it makes a really cool ringtone ^^

GI Joe
Ok, why no.1? It just so happens the song rings in my ears almost forever! First of all, it's like the Ultimate patriot song with an awesome 80s feel to it. It's funny, almost laughable, but you got to admit it was memorable. You could feel they are winning, I mean they are throwing Cobra and Destro about!
I bet if you watched the TV series years ago, then watch the Live-Action film years later, I bet the first thing that pop in your head is the theme song. Batman saw Six films with the Dark Knight being the greatest of them, TMNT saw Four films including the CG film, Transformers was recently released last year with its sequel coming in 2009 (that's right, summer next year!) and X-men already saw a Trilogy with the prequel, X-men Origin: Wolverines releasing on May 2009 (woot!).
All of them were made into films with the exception of GI JOE... oh, wait. I forgot ^^
