Ben 10!
He's a kid and he wants to have fun
But when you need a superhero,
He gets the job done!
Ben 10!
With the device that he wears on his arm, 
He can change his shape and save the world from harm!
When trouble's taking place, 
He gets right in its face!
Ben 10!
When lives are on the line, 
It's hero time!
Ben 10!
