Ben 10: Ultimate Alien is a sequel series to Ben 10: Alien Force. It premiered on April 23, 2010. The style in this series is different from the Alien Force series. This follows now a 16-year old Ben and Gwen, and 17-year old Kevin. 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". It went under the working title, Ben 10: Evolution.

A new feature in the series is Ben's new car.

Opening
thumb|right|200px|Ultimate Alien IntroThe opening shows all the aliens Ben has ever turned into and the Ben 10,000 aliens, but Dwayne McDuffie has stated that not all of them are unlocked on Ben's current playlist as some think. In the background there are also clips that show some scenes from Alien Force and some from Ultimate Alien. Eon is not present due to the fact that his DNA is no longer in the Codon Stream.

If Ultimate Wildmutt were to apear in the series, a second version of the opening may likely be produced.



Trivia

 * It is the first series for Ben not to start-off with only ten aliens. Now he starts with 18
 * On the Ultimate Alien show page on Cartoon Network Asia (http://www.cartoonnetworkasia.com/minisite/ben10_ua/index.php), when you go to Characters and click on Cannonbolt (the picture shows Ultimate Cannonbolt), the picture of him is from the original series, as you can see that the Omnitrix is on his forehead, and it is clearly the one from the original series.
 * Revealed in the Symbionic Titan premiere by Dee Bradley Baker many new aliens are going to appear that he doesn't even know about.
 * In Mexico, the show premiered in October 10, in a 10 hour marathon (starting at 10 AM), with the first chapter of the series airing at 8:30 PM. In T.V. ads, the "10.10.10." date was shown. (The tenth day of the tenth month of the tenth year of this millennium.) The show was dubbed as "Ben 10: Alien Supremacy" (Ben 10: Supremacía Alienigena) this is because there is no accurate translation of the word "Ultimate" in Spanish, while its predecessor had a much more literal translation.

 * In CN Poland, "Ultimate Alien" is the fifth season of "Alien Force".
