Avengers: Earths Mightiest Heroes theme song:

"Our world's about to break, tormented and attacked, lost from when we wake, with no way to go back. I'm standing on my own, but now I'm not alone. Avengers Assemble! Always we will fight as one til the battle's won, with evil on the run we never come undone. Assembled we are strong, forever fight as one, assembled we are strong, forever fight as one."
