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 250 aired episodes, 20 unaired but ordered making a grand total of 270 episodes across nineteen seasons, four made-for-TV movies, 10 shorts, and 1 special but that was counted as an episode for Generator Rex as of December 4, 2016.
