'Ben 10' is a popular TV series produced by 'Cartoon Network Studios'.

The series follows the life of a boy, Ben Tennyson, who acquires the ability to transform into 10 aliens with the use of a device called the 'Omnitrix'. Although there are 10 original 'Ben 10' aliens, as the series progresses, more aliens are added to the 'Omnitrix'.

There are several parts to the 'Ben 10' franshise: the original 2005 series, 'Ben 10: Alien Force', 'Ben 10: Ultimate Alien', 'Ben 10: Omniverse', the 2016 'Ben 10' TV series, and even the live action TV series on Cartoon Network. Apart from this there are films and video games in the 'Ben 10' franchise.

The number of aliens in 'Ben 10' increases with each addition  to the series, starting off with 10 'Ben 10' original aliens and building up to more than 57 aliens in 'Ben 10: Ultimate Alien' and 'Ben 10: Omniverse'.  

Kevin Levin is the new enemy of Ben 10 with Vilgax being in the Null Void. Kevin Levin possesses the Antitrix, a variant of the Omnitrix, that allows him to access aliens of Ben 10 in their altered versions. Gwen Tennyson is one of the characters in 'Ben 10' who plays the role of the wife of Ben 10.
