Ben 10 Season 4 Episodes
Season 4 Episode Guide
15 Episodes 2007 - 2008
In the fourth and final season of the animated adventure series, Ben Tennyson keeps up his hero act with help from the Omnitrix, a special watch-like device capable of temporarily turning him into 10 different aliens.\ Alongside his grandfather Max and cousin Gwen, Ben keeps the universe safe from various alien clans who are fighting for control of the universe. He faces familiar foes---Vilgax, the Forever King and Dr. Amino---throughout the season while also encountering new troublemakers, including a corrupt road crew that steal the Tennyson RV, and a mob boss who's holding a woman hostage until her mutant sons come up with the ransom. The Plumbers, a secret organization of which Grandpa Max was once a member, continue to protect humans from alien threats as well. The group's work hits close to home, however, when a Plumber (and a Tennyson relative) decides to marry an extraterrestrial from the Sludge alien clan, with whom the Plumbers have been feuding. The regular voice cast features Tara Strong, Meagan Smith, Paul Eiding, Dee Bradley Baker, Steven Jay Blum and Jim Ward.
