General Episodes Cast

Ben 10, later known as Ben 10 Classic or Classic Ben 10, is an American animated series created by the group Man of Action and produced by Cartoon Network Studios. The pilot episode And Then There Were 10, aired on December 27, 2005, as part of a sneak peek of Cartoon Network's Saturday morning lineup.

This series was followed-up by three sequels called Ben 10: Alien Force, Ben 10: Ultimate Alien, and Ben 10: Omniverse, and was later rebooted.


Ten-year-old Ben Tennyson, his ten-year-old paternal first-cousin Gwen, and their paternal Grandpa Max start their summer camping trip. Ben goes stomping off into the woods after another fight with Gwen, whom he is not happy to have along on the trip, and is almost crushed when a meteor crash lands, only to discover it’s an alien cargo pod. When he examines it, he finds a mysterious, watch-like device, called the Omnitrix. As Ben reaches inside the pod for it, the device attaches permanently to his wrist and gives him the ability to transform into a numerous variety of alien life-forms, each with their own unique powers and abilities. Although Ben realizes that he has a responsibility to help and save others with these new abilities at his disposal, he is not above a little ten-year-old super-powered mischief now and then. Along with Gwen and Max, Ben embarks on an adventure to fight evil, both extraterrestrial and earthly. Ben has faced lots of villains including villains fighting together in a team or a partner once such as when Vilgax and Kevin 11 teamed up to destroy Ben and steal the Omnitrix.

Theme Song

The theme song of Ben 10 was sung by Moxy and written by Andy Sturmer. In the first and second seasons, Ghostfreak was the ninth alien in the theme song. Cannonbolt replaced Ghostfreak as the ninth alien in the third and fourth seasons.


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!)

Armed with power, 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!
Ben 10! (Ben 10! Ben 10! Ben 10! Ben 10! Ben 10! Ben 10!)
