Welcome to Ben 10 page

Ten-year-old Ben Tennyson, his ten-year-old paternal first-cousin Gwen Tennyson, 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 finds an alien pod on the ground. When he examines it, he finds a mysterious, watch-like device, called the Omnitrix. 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 Kevin 11 and Vilgax fought Ben.

Ben 10 Theme Song


The theme song of Ben 10 was sung by Moxy. In the First and Second Season Ghostfreak was the ninth alien in the theme song. Cannonbolt replaced Ghostfreak as the ninth alien in the Third and Fourth Season.


  • 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!)


  • Ben and Gwen's hostile fights

One thing to take note of for the intro is that European theme songs play at one pitch higher than North American Theme Songs. Examples: Spanish Intro (North American Spanish) Spanish Intro (European Spanish) This series has the most amount of voice actors out of all the three current series. This series debuts the most number of aliens in any series with a total of 23 (and 5 mentioned) debuting whereas Alien Force features 12 new aliens and Ultimate Alien features 10.

Recurring lines in the series are: "Should be?", "Oh man!" and "It's hero time!". This is the only show in the series with a theme song with words. Ghostfreak was replaced by Cannonbolt in the theme song from season 3, due to Ghostfreak's escape.

A remixed version of the theme was played in Ben 10: Race Against Time.

By the end of the series Ben had a total of 20 aliens he could turn into; including Eon.

In Norway, Sweden and Denmark, episode 22 and 23, 24 and 25, and 27 and 28 switched place. Monster Weather becomes episode 33, Super Alien Hero Buddy Adventures becomes 34, Under Wraps becomes 35, and The Unnaturals becomes 36. Also in episode 36 the credits at the beginning of the episode is shown before the opening theme. Also, Goodbye and Good Riddance and Ben 10: Race Against Time was aired before Ben 10 vs. the Negative 10 (Part 1) and 2 and Secret of The Omnitrix were aired between the third and fourth seasons. In the latest reruns, the theme song has been shortened (except, for some reason, in the episodes The Negative 10: Part 1 and 2).

  • The current airings on Boomerang have now gone back to the original theme song's length.

In Poland, episodes 52, 51 and 50 (Goodbye and Good Riddance and Ben 10 vs. the Negative 10) was switched, Goodbye and Good Riddance was episode 50, Ben 10 vs. the Negative 10 part 1 was episode 51 and part 2 of this episode was 52. By the end of the series, and by the time half of the Alien Force series ended, some people were confused if some of these episodes were canon. Since some of the season 3 and 4 episodes were not according to the story. Some of the aliens like BenViktor were confusing people because in Alien Force, Azmuth said every alien DNA sample were collected in to the Omnitrix/Ultimatrix in the whole Milky Way Galaxy, confusing because the Anur System was part of their galaxy, but it is possible that Anur Phaetos, Transyl, and Khofos along with Luna Lobo were in a dimension and as mentioned in Alien Force, no one that travelled there has ever came back to tell stories about it until Ben's Team went to it in Ben 10 Alien Force: Vilgax Attacks In Heroes United, Rex makes his own theme song similar to Ben's.
