Song lyrics Ben 10 Theme Song by Ben10

The started when an alien
Device did what it did
The stuck itself upon his
Wrist with secrets that it hid.
Now he's got super
Powers, he's no
Ordinary kid
He's Ben 10! (Ben 10!)

So if you see him you
Might be in for a big suprise
He'll turn into an alien
Before your very eyes
He's tiny, creepy,
Fast, and strong, he's
Every shape and size
He's Ben 10!(Ben 10!)
Taken from AlbumSongAndLyrics.com
With all new powers
He's on the case
Fighting off evil from
Earth or space
He'll never stop till he
Makes them pay
'Cause he's the baddest
Kid to ever save the day
He's Ben 10! (Ben, Ben!)
