Plot

Ben 10: Ultimate Alien takes place a few weeks after the events of the previous series. With the Omnitrix having been destroyed in the series finale of Alien Force, Ben Tennyson, now sixteen years old, must learn to master the powers of the Ultimatrix, a modified version of the Omnitrix which has the ability to evolve Ben's alien forms into much more powerful versions known as "ultimate forms." The series begins with the exposure of Ben's secret identity to the world by J. Jonah "Jimmy" Jones, a young internet conspiracy theorist who deduces his identity by studying alien sightings in Ben's hometown of Bellwood. Ben's exposure polarizes public opinion, with younger fans idolizing him, and adults (particularly news anchor Will Harangue) deriding Ben as a menace to society. Ben is now forced to adjust to a new life that not only involves battling the forces of evil alongside his cousin Gwen Tennyson and his best friend Kevin Levin, but also his struggle against the pitfalls of his new-found fame.
