It all starts when Ben discovers a strange device, the Omnitrix, that locks itself on his wrist. With “the watch,” Ben has the ability to morph into bizarre aliens like Heatblast, Upgrade, Grey Matter, Stinkfly, Ghostfreak, Ripjaws, Wildmutt and Diamondhead, each with its own set of special abilities, while still maintaining his 10-year-old personality. With these powers, he can play the part of a superhero, righting wrongs, saving the world and getting into some old-fashioned kid-style trouble. Ben and the Omnitrix catch the attention of an intergalactic bad guy named Vilgax who will stop at nothing to get the kind of power that Ben has managed to acquire.

When he’s not tangling with Vilgax’s cronies or other earthbound villains, Ben is traveling the country in his Grandpa Max’s RV. Grandpa Max is a good-humored, open-minded and unsuspecting mentor who wants to put a little more excitement into his grandson’s life by taking him on a cross-country summer vacation. Ben and Grandpa are joined on their road trip by Ben’s cousin Gwen, who is smart, level-headed and not exactly thrilled to be along for the ride. Still, as the voice of reason, she’s invaluable in times of chaos, which is pretty much all the time.

Ben’s main challenges are finding the best way to harness his power and making good decisions about when to summon his inner superheroes. It’s a good thing that his worldly and wise grandfather and shrewd cousin Gwen are there to keep him in check – and bail him out of trouble when he needs it.

Theme Song Lyrics:
It started when an alien device did what it did
And 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!)
(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!
(Ben 10!)
(Ben 10!)

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!

This song is written by Andy Sturmer and is performed by Moxy.
