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, freaky, fast and strong he's every shape and size,
he's Ben 10
(Ben 10)
All new powers he's on the case. Fighting all 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.
