Ben Tennyson is 15 when Ben 10: Alien Force begins. Five years have passed since the original series, and the show treats that gap as the whole point.

The Omnitrix Recalibrates
Cartoon Network premiered Ben 10: Alien Force on April 18, 2008, as a direct sequel to Ben 10 (2005–2008). Set five years later, it takes a darker turn. Ben, now a teenager, once again joins the Prototype Omnitrix and finds it has reconfigured, giving him 10 new alien forms stronger than anything he had before.
The premise holds. Ben, his cousin Gwen and his former enemy Kevin Levin set out to find his missing Grandpa Max, who vanished while investigating the Highbreed plot and left behind only a few cryptic messages.
Yuri Lowenthal Leads the Cast
Lowenthal voices Ben, Ashley Johnson voices Gwen, and Greg Cipes voices Kevin. The casting matters because the show leans on all three.
Gwen is 15 and far more skilled with her magical powers than she was as a child. She can shape energy into ropes, bridges, shields and projectiles. She is no longer fiery or short-tempered, and her concern for Ben reads clearly.
Kevin Levin Switches Sides
Kevin is the better turnaround. A former nemesis, he now works as an alien tech dealer, gets pulled into the Highbreed plot by accident, and joins Ben to make up for what he did. He can absorb the properties of any solid matter he touches, like rock or steel, which gives him greater strength and protection in a fight.
The Working Title You Never Saw
The series was produced under the working title Ben 10: Hero Generation. It was created by Man of Action — Duncan Rouleau, Joe Casey, Joe Kelly and Steven T. Seagle — and produced by Cartoon Network Studios.
Four Emmy Nominations, One Win
It ran three seasons and 46 episodes, ending March 26, 2010. It earned four Emmy nominations and won one, for Outstanding Sound Mixing – Live Action and Animation. A sequel, Ben 10: Ultimate Alien, followed in 2010.
A Lego Line of Alien Figures
There was also a Lego Ben 10: Alien Force line, built around Ben’s alien forms — Spidermonkey, Swampfire, Chromastone, Humungousaur, Jet Ray and Big Chill. The sets used Bionicle parts and let kids build an action figure of one alien each.
That is a merchandising footnote, not a creative one. Six figures is still a decent sign that the aliens read as separate characters.
Where the Hunt Stretches Thin
The darker turn is not a pose. Aging Ben to 15 and giving him a missing grandfather to chase forces the show to slow down, and the Kevin reversal gives it a character who has to earn his place every week.
It was nominated for four Emmy Awards, winning one for Outstanding Sound Mixing – Live Action and Animation.
The weakness is the hunt itself. With 46 episodes across three seasons, the search for Max stretches thinner than the premise can carry.

Growing the hero up works in this show’s favor. It does not always fill the time, but when it works, it works.
