When Ben 10: Alien Force premiered on Cartoon Network in April 2008, it marked a bold evolution for the franchise. Gone were the summer road trip vibes and the 10-year-old Ben Tennyson. In its place was a darker, more serialized story featuring a 15-year-old Ben, who had hung up the Omnitrix for five years. The world had moved on, but a new alien threat—the High Breed—forced him to reunite with his estranged cousin Gwen and his former rival, Kevin Levin.
