Ben 10: Ultimate Alien (formerly called Ben 10: Evolution and Ben 10: Ultimatrix[1]) is the third iteration of the Ben 10 franchise and the sequel of Ben 10: Alien Force (formerly called Ben 10: Hero Generation). It premiered on April 23, 2010. The art and story styles in this series is similar to Alien Force. The series follows 16-year old Ben and Gwen along with 17-year old Kevin. The series premiered in the United Kingdom, Australia, Asia, Middle East and Latin America on 10/10/2010 at 10:00 A.M. on Cartoon Network. This is also the day a marathon of the episodes came on with a contest for the 10/10/10 event in America. This series is followed-up by another sequel series called Ben 10: Omniverse.


Ben's secret identity has been revealed to the world and he is now an international mega-star super hero, loved by kids all-over the world, but distrusted by many adults such as reporter Will Harangue. Armed with a mysterious, more powerful Omnitrix called the Ultimatrix, Ben will face being hunted by rogue alien threats, human mercenaries, and assassins hired by opposing adults. Ben will be in places he has never been before; such as the Forge of Creation. The main enemy of the first season is named Aggregor who is after the "Ultimate Prize."
