Ben 10: Destroy All Aliens

The events take place after the last episode of the original Ben 10 series, when Ben Tennyson (Tara Strong) has the Omnitrix and a long list of alien forms to switch between. A Mechamorph warrior called Retaliator blames Ben for a wrong he never committed and sets out to destroy every alien he can find. Victor Cook directs, and Ben, with Gwen (Meagan Moore) and Grandpa Max beside him, has to protect every alien form he carries.
