"It started when an alien device did what it did..."Ben 10 is a series of cartoons made by a group called Man of Action (Duncan Rouleau, Joe Casey, Joe Kelly, and Steven T. Seagle) that has aired on Cartoon Network since 2005. It was the group's first collaboration.The series follows a boy named Ben Tennyson who, on the first night of a summer road-trip with his grandfather Max and his cousin Gwen, stumbles across an alien device known as the Omnitrix which bonds itself to his wrist like a watch. Ben finds that the device has alien DNA encoded in it which allows him to transform to a variety of alien species, with their own set of skills. From then on, Ben uses the device to take on any threats that come his way, while causing a few bouts of mischief in the process. As he grows as a hero, Ben learns that he didn't gain the Omnitrix by coincidence and finds that his family has been involved with aliens long before he has.Taken as a whole, the Ben 10 franchise is Cartoon Network's longest-running series with a grand total of 278 episodes across 20 seasons, four made-for-TV movies, 40 shorts, and 1 specialnote as of August 16, 2017.
