Season 2 Episode 27 – Catch a Falling Star
Charmcaster and Darkstar team up to destroy Ben, Gwen and Kevin.
Taking place a few weeks after where Ben 10: Alien Force leaves off, Ben 10: Ultimate Alien follows the now sixteen-year-old Ben. The Omnitrix has been destroyed and Ben must learn to master the secrets of the new Ultimatrix, a gauntlet-like version of the old Omnitrix that not only gives him access to all of his original powers and abilities, but also allows him to evolve his alien forms into even stronger and even more powerful versions - ultimate forms. The second season features more self-contained stories rather than employing an overall storyline, although a real storyline is developing with the appearance of the mysterious but dangerous Old George and the extradimensional demon Lucubra.
