Every Ben 10 Animated Series, Ranked Worst To Best

Ben 10 has had a total of five animated shows featuring the titular hero and his alien alter-egos, but not every show has been a success. The original Ben 10 first aired in 2005 on Cartoon Network and immediately became a hit with young viewers who loved the idea of a kid hero who could transform into a variety of super-powered aliens. Along with his cousin Gwen, his grandpa Max, and some friends who appear in later series, Ben Tennyson uses the power of the Omnitrix to save the universe from evil forces time and time again.
