It started when an alien device did what it did

It stuck itself upon his wrist with secrets that it hid

Now he's got superpowers he's no ordinary kid

He's Ben 10, Ben 10

So if you see him you might be in for a big surprise

He'll turn into an alien before your very eyes

He's slimy, creepy, fast and strong

He's every shape and size, he's Ben 10

Armed with 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 day

Ben 10

Armed with powers he's on the case
