The series follows the adventures of sixteen-year-old Ben Tennyson, wielder of the Omnitrix, an extremely powerful watch-style device that allows Ben to change into a multitude of various aliens; each with their own special abilities and skills. The storylines alternate between that of eleven-year-old Ben (one year after the original series) and sixteen-year-old Ben (a few months after Ben 10: Ultimate Alien). After Gwen leaves for college and Kevin leaves to be closer to her, Ben gets a new partner, a rookie by-the-book alien plumber named Rook Blonko (surname first). On a mission to explore a secret underground alien city named Undertown, Ben explores the quirkier side of things in the alien underground and discovers that enemies from his past are looking for a rematch.
Five years ago, Ben Tennyson faces off with a new enemy,a red Galvanic Mechamorph, Malware. Five years later, Kevin and Gwen leave when Gwen takes early enrollment in an Ivy League college, and Kevin moves to be near her. Ben is forced to fight crime alone, but Grandpa Max (Magister Tennyson – the commander of the Earth-base's Plumbers) gives him a new partner, rookie Plumber Rook Blonko. Ben and Rook end up in their first team-up when Mr. Baumann's store is targeted for destruction by three alien criminals (Bubble Helmet, Fistina, and Liam) as part of their protection racket. An intergalactic hunter named Khyber watches Ben from the shadows.
