Ben 10: Ultimate Alien

Ben 10: Ultimate Alien is the 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 of yet. Ben has unlocked all of his original aliens and a few new ones thanks to the help of his Future Self. The background also shows clips from both Alien Force and Ultimate Alien episodes.



Trivia

 * It is the first series for Ben to not to start-off with only ten aliens. He starts with 18 aliens, now currently 45 (minus ultimate forms).
 * 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.
 * 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 Brazil the same thing happened.
 * Cartoon Network always mistranslated "Ben 10: Ultimate Alien" as "Ben 10: Alien Force" in the 'coming up next' menu.
 * Three of the episodes (The Forge of Creation, ...Nor Iron Bars a Cage and Ben 10,000 Returns ) shows young Ben, Gwen and Kevin.
 * All of the aliens shown in the opening has moved the Ultimatrix symbol to their chest. This is to make it easier to change alien.
 * An Ultimate Wildmutt toy is going to be in stores in July of 2011 in USA
 * Episodes 1 through 10 were intended be season 1 and episodes 11 through 20 were to be season 2 but it was merged into one season due to Cartoon Network US' schedule but in the UK it was split.
 * Dwayne McDuffie confirmed that the season 2 arc starts at episode 7.
 * All the Ultimatrix Aliens (exception of Alien X, Upgrade, Rath & Buzzshock) will be provided by Dee Bradley Baker
 * It is unknown if there will be a live movie for the series.
